Volvorax gen. nov. is validated instead of invalid Endocoenobium Ingold and E. eudorinae Ingold (in New Phytol. 39: 97. 1940) which were not validly published due to the lack of Latin diagnosis/description. Since the host range was extended to include Eudorina unicocca and Pandorina morum (Canter in Bot. J. Linn. Soc. 91: 95-116. 1995), the species epithet is not preserved, being changed to ‘ingoldii’ to honour the name of Cecil Terence Ingold (1905-2010).

Emerging viral infections such as the zika virus, dengue virus, ebola virus, corona virus are afflicting millions of human populations worldwide. Therefore, the development of new treatments against emerging infectious diseases has become an urgent task. The availability of commercially viable, safe, and effective antiviral drugs still remains a big challenge. Mushrooms are considered as an untapped reservoir of several novel compounds of great value in industry and medicine. Although exploration, and exploitation of the therapeutic importance of fungal metabolites has started early with the discovery of penicillin, mushrooms's pharmacological potential has much less been investigated. This article briefly reviews the antiviral potentials of mushrooms to combat deadly disease outbreaks caused by emerging and re-emerging viruses. Altogether 69 mushroom species with potent antiviral agents and mode of action against prominent viruses such as human immunodeficiency virus, influenza, herpes simplex virus, hepatitis B and C viruses, corona viruses etc. are listed in this study. Further studies are encouraged to discover more novel potent antiviral agents or evaluate already known compounds from those mushrooms with clinical trials.

The Basidiomycota constitutes a major phylum of the kingdom Fungi and is second in species numbers to the Ascomycota. The present work provides an overview of all validly published, currently used basidiomycete genera to date in a single document. An outline of all genera of Basidiomycota is provided, which includes 1928 currently used genera names, with 1263 synonyms, which are distributed in 241 families, 68 orders, 18 classes and four subphyla. We provide brief notes for each accepted genus including information on classification, number of accepted species, type species, life mode, habitat, distribution, and sequence information. Furthermore, three phylogenetic analyses with combined LSU, SSU, 5.8s, rpb1, rpb2, and ef1 datasets for the subphyla Agaricomycotina, Pucciniomycotina and Ustilaginomycotina are conducted, respectively. Divergence time estimates are provided to the family level with 632 species from 62 orders, 168 families and 605 genera. Our study indicates that the divergence times of the subphyla in Basidiomycota are 406-430 Mya, classes are 211-383 Mya, and orders are 99-323 Mya, which are largely consistent with previous studies. In this study, all phylo-genetically supported families were dated, with the families of Agaricomycotina diverging from 27-178 Mya, Puccin-iomycotina from 85-222 Mya, and Ustilaginomycotina from 79-177 Mya. Divergence times as additional criterion in ranking provide additional evidence to resolve taxonomic problems in the Basidiomycota taxonomic system, and also provide a better understanding of their phylogeny and evolution.

The aim of this study was to describe the incidence of contamination of pharmaceutical products by melanized fungi and to consider control measures in relation to bioburden and cleanrooms. This study reviews and analyses pharmaceutical product recalls and offers incidence rates of fungal detection from a typical cleanrooms. The recalls include some serious cases which resulted in the loss of life. Of different types of fungal contamination incidences some of the most damaging have been due to melanized fungi (‘black mould’), such as Exserohilum rostratum. The focus of the article is with melanized fungi. The study concludes that, from the review of recent pharmaceutical product recalls, fungal contamination is either increasingly common within cleanroom environments or the accuracy of sampling and the level of reporting has risen. The prevalence of melanized fungi in pharmaceutical facilities rests on specific virulence factors particular to these types of fungi, which are outlined. The article identifies a gap in the way that such fungi are screened for using available cultural methods. The article provides some control strategies, including assessing the suitability of disinfectants and biocides, for reducing the risk of melanized fungal incidences within the pharmaceutical facility. Understanding the fungal risk to pharmaceutical products remains a poorly understood and often overlooked aspect of pharmaceutical microbiology. This article helps to identify this risk and offer some guidance to those involved with pharmaceutical products manufacture in relation to bio-contamination control strategies.

Jimtrappea guyanensis gen. sp. nov., Castellanea pakaraimophila gen. sp. nov., and Costatisporus cyanescens gen. sp. nov. are described as new to science. These sequestrate, hypogeous fungi were collected in Guyana under closed canopy tropical forests in association with ectomycorrhizal (ECM) host tree genera Dicymbe (Fabaceae subfam. Caesalpinioideae), Aldina (Fabaceae subfam. Papilionoideae), and Pakaraimaea (Dipterocarpaceae). Molecular data place these fungi in Boletaceae (Boletales, Agaricomycetes, Basidiomycota) and inform their relationships to other known epigeous and sequestrate taxa within that family. Macro- and micromorphological characters, habitat, and multi-locus DNA sequence data are provided for each new taxon. Unique morphological features and a molecular phylogenetic analysis of 185 taxa across the order Boletales justify the recognition of the three new genera.

The rhodopolioid species of Entoloma (subgen. Entoloma) in Norway are presented. The rhodopolioid clade consists of tricholomatoid or collybioid, rarely omphalinoid, ectomycorrhizal species. Altogether 24 species of the rhodopolioid clade... more

The rhodopolioid species of Entoloma (subgen. Entoloma) in Norway are presented. The rhodopolioid clade consists of tricholomatoid or collybioid, rarely omphalinoid, ectomycorrhizal species. Altogether 24 species of the rhodopolioid clade were recorded and verified by rDNA ITS sequence data, of which 10 are here reported as new to Norway, including three apparently undescribed species. Four different eco-geographical elements can be distinguished from our material; (i) the southern (boreonemoral) Tilia-Quercus-Corylus element, (ii) the boreal-arctic-alpine Salix-Alnus-Betula element, (iii) the arctic-alpine Salix(-Dryas) element, and (iv) the boreal Betula(-Picea) element. All 24 species are commented in the taxonomic part, arranged according to the five well-supported clades from phylogenetic analyses.

Trichoderma is a cosmopolitan fungus abundantly present in fertile soils and is well known for its mutualistic and endophytic relationship with other plant bodies. The diversified species of trichoderma have been well described in literature for its biocontrol capacity and its key role in health and plant growth. The species of trichoderma varies in different soils and could only be identified after specific procedures. The present study was designed to investigate the various species of trichoderma in wheat fields of central Punjab area of Pakistan which consists of 19 districts. Three soil samples from each district of central Punjab have been isolated to determine the prevalence/diversity of various Trichoderma species. The samples were grown on complete media to isolate various species of fungi. The isolated species were then analyzed further on minimal media for the production of Trichoderma species. The result revealed the presence of Trichoderma in all samples. The morphological characteristics led to the identification of five species of Trichoderma in all samples. The most prevalent strains occurring in some districts of Punjab were Trichoderma Harzianum (84%) followed by Trichoderma viridae (63%), Trichoderma reesei (52%), Trichoderma koningii (31%) and Trichoderma Hamatum (26%). The district wise the most prevalent species is Trichoderma harzianum it is found in 6 districts with maximum prevalence in 3 districts i.e Hafizabad, Mandi bahuddin and Sahiwal. While the least prevalent species found to be was Trichoderma Hamatum having occurrence in only 2 districts named Faisalabad and Khanewal. The study showed the presence of different strains of trichoderma in all districts of central and upper Punjab region of Pakistan. The present study validated the presence of Trichoderma species in major districts of Punjab regions and also speculates its mutualistic role in different soils.

Cortinarius is the largest genus of ectomycorrhizal fungi worldwide. Recent molecular studies have shown high levels of morphological homoplasy within the genus. Importantly, DNA phylogenies can reveal characteristics that have been either over- or underemphasized in taxonomic studies. Here we sequenced and phylogenetically analysed a large set of pan-European and North American collections taxonomically studied and placed in Cortinarius sect. Bicolores and sect. Saturnini, according to traditional morpho-anatomical criteria. Our goal was to circumscribe the evolutionary boundaries of the two sections, to stabilize both the limits and nomenclature of relevant species, and to identify described taxa which, according to our current understanding, belong to other lineages. Our analysis resolves two clades: /Bicolores, including 12 species, one of which is new to science, and /Saturnini, including 6 species. Fifteen binomials, traditionally treated in these two sections based on morphology, do not belong to the above two phylogenetic clades. Instead, six of these latter are clearly placed in other clades that represent sect. Bovini, sect. Sciophylli, sect. Duracini and sect. Brunneotincti. The presence or absence of blue pigments and the detection of specific odours emerge as clearly misleading taxonomic features, but more surprisingly, spore size and ecology can be misleading as well. A total of 63 type specimens were sequenced, 4 neotypes and 2 epitypes are proposed here, and 1 new combination is made.

An intensive recollection of Ascomycetes was carried out within the best-known preserved Mexican tropical montane cloud forest patch dominated by Fagus grandifolia subsp. mexicana. This relict tree species has a fragmented and restricted distribution in the mountains of eastern Mexico. Other Mexican endemic Fagaceae species show dominance in this forest patch. Historically, records of Ascomycetes fungi in this type of forest are scarce. The present study found 170 specimens belonging to 61 species, of which 30 are new records for the state, while 10 species are cited for the first time in the country. Most of the recorded Ascomycetes species are intimately associated to Fagaceae tree species (Fagus and Quercus). From these, many are endophytes belonging to the Order Xylariales, while others grow on decaying wood, fallen branches, leaves and/or litter (possibly mycorrhizal). This interesting close relationship between fungi and Fagaceae trees must be studied and analyzed.

Talaromyces verruculosus, T. aculeatus and T. apiculatus are the only Talaromyces species that produce conidiophores with ampulliform phialides, which taper into very thin necks and have rough walled, globose conidia. In this study, we introduce five new species with similar micromorphological features, but were found to display unique macro-morphological characters. Talaromyces australis (CBS 137102 T) is distinguished by its restricted growth on CYA at 25 and 37 C (16e24 mm; 9e13 mm) and red pigments produced on most media. Talaromyces kendrickii (CBS 136666 T) is distinguished by its inability to grow on CYA at 37 C. Talaromyces veerkampii (CBS 500.78 T) grows rapidly on MEA (38e42 mm) and colonies on YES has a bronze green reverse. Talaromyces fuscoviridis (CBS 193.69 T) colonies have dark green reverses on MEA and commonly produces red exudates on other media. Talaromyces stellenboschiensis (CBS 135665 T) grows faster on CYA at 25, 30 and 37 C (40e45 mm; 48e53 mm; 35e40 mm) than the others. Morphological findings were supported by both multigene phylogenetic analyses and the extrolites produced by these species.

— Eight nomenclatural novelties (new names and new combinations) are proposed in Amanita: A. albopulverulenta, A. congolensis, A. flaccida, A. lavendula, A. neomurina, A. neoneglecta, A. persicina, and A. reidi-ana. The plate associated with the protolog of A. nivalis is the name's sole syntype and must be the lectotype of A. nivalis. The improperly designated neotype of A. nivalis is proposed as an epitype of that species. A lectotype is proposed for A. mappa var. lavendula.

Coltriciella sonorensis is described here as a new
species from Mexico. It is characterized by pleuropodal,
flabelliform basidiomes, rounded to elongated or daedaloid
pores, a well-developed sub-hymenium, and oblong to
cylindrical basidiospores, slightly attenuated towards the apex.
The specimen was collected on soil in an open Quercus stand
in mixed Quercus–tropical deciduous forest in the Sierra de
Álamos–Río Cuchujaqui Biosphere Reserve, Sonora, Mexico.
From a phylogenetic perspective, the species appears to be
related to C. oblectabilis, also occurring in Mexico.

Binderoboletus segoi gen. and sp. nov., Guya-naporus albipodus gen. and sp. nov. and Singerocomus rubriflavus gen. and sp. nov. (Boletaceae, Boletales, Basidiomycota) are described from the Pakaraima Mountains and adjacent lowlands of Guyana. Xeroco-mus inundabilis, originally described from the central Brazilian Amazon and based solely on the type collection , is redescribed from numerous collections from Guyana and transferred into Singerocomus. These boletes occur in Neotropical forests dominated by ectomycorrhizal trees in the genera Dicymbe (Faba-ceae subfam. Caesalpinioideae), Aldina (Fabaceae subfam. Papilionoideae) and Pakaraimaea (Diptero-carpaceae). Three of the species were repeatedly found in a multiyear sporocarp survey in Dicymbe cor-ymbosa-monodominant forest. Macromorphological, micromorphological, habitat and multilocus DNA sequence data are provided for each species. A molecular phylogenetic analysis based on a large taxon set across the Boletaceae justifies erection of the new genera.

The genus Inonotus is considered polyphyletic of which the recognized genera are Inocutis, Inonotus s. str., Inonotopsis, Mesularia, Onnia, and Pseudoinonotus. Twenty-four species of the genus Inonotus s.l. were studied in this work based upon the examination of 304 specimens deposited on the Herbaria ENCB, MEXU, BCMEX, IBUG, XAL, NY, BPI, and ARIZ. In Mexico, we found 24 species, corresponding to 5 of the 6 genera segregated. Four of these species are new records: Inocutis rheades (Pers.) Fiasson and Niemelä, Inonotus arizonicus Gilb., I. porrectus Murrill, and I.
quercustris M. Blackw. and Gilb. Furthermore, I. rickii􀀃􀀋 in North America. A key to identify the Mexican species of Inonotus s.l. is presented.

Most of the species of myxomycetes from Mexico are well documented, but their patchy geographical and temporal distribution responds to the individual efforts carried out in different areas of the territory over time. As such, even for well-studied areas, new projects can substantially increase biodiversity-based information. The present study constitutes an update of the myxomycete catalog of the state of Veracruz, carried out from an intensive study in a section of Abies religiosa at the Cofre de Perote National Park. The methodology consisted in field collections, complemented with a laboratory isolation process using diverse substrates from different locations. The study was carried out in two years (2018-2019) and in two seasons (dry and rainy). A total of 30 taxa were identified, out of which, 21 species were not previously known for the state of Veracruz, increasing the number of myxomycetes known in such state to 168 species, making it one of the most diverse states in Mexico, with approximately 45% of the known species in the country.

Phylloporia rzedowskii and Phylloporia ulloai,
both collected in tropical forests of the Sierra of the
Huasteca Potosina, San Luis Potosi, Mexico, are described
as new species. The main critical morphological features
that characterize them are the pileus shape, the pore
diameter, the basidiospores shape and size, and, possibly,
their ecology, such as the host relationships (specificity/
preference). Both species also form distinct clades in
phylogenetic analysis based on partial DNA sequences data
from the nuclear ribosomal LSU. An identification key for
10 species reported from the Americas is proposed.

Brandrud T. E., Dima B., Liimatainen K. & Niskanen T. (2017) Telamonioid Cortinarius of the C. puellaris group from calcar-eous Tilia forests. – Sydowia 69: 37–45. Four species belonging to the Cortinarius puellaris group are presented, including the two new species C. biriensis, C. subpu-ellaris and the recently described C. puellaris. Based on type studies, it is shown that the fourth species in the group should be named C. intempestivus (=C. cristatosporus). The species co-occur and are all studied mainly from SE Norwegian calcareous Tilia forests, but at least some of them also occur in Quercus(-Carpinus) forests in temperate-mediterranean areas of C-S Europe, and are apparently widespread and much overlooked. These are all tiny, small, ochre-redbrown telamonioid cortinarii with strongly to spiny ornamented spores. Phylogenetically, the taxa are well-distinguished by 8 to 22 ITS differences. Together with two taxa only known from ectomycorrhizal ITS sequences, they constitute an apparently well-supported clade with uncertain affinity.

In this study, PCR fingerprinting using the universal primer T3B was applied to distinguish among clinical and environmental species of the Sporothrix complex, Sporothrix brasiliensis, S. globosa, S. mexicana, S. pallida, S. luriei and S. schenckii sensu stricto. The T3B fingerprinting generated clearly distinct banding patterns, allowing the correct identification of all 43 clinical and environmental isolates at the species level, what was confirmed by partial calmodulin gene sequence analyses. This technique is reproducible and provides the identification of all species of the Sporothrix complex with sufficient accuracy to be applied in clinical mycology laboratories as well as in epidemiological studies in order to obtain a better understanding of the epidemiology of sporotrichosis.

This study documents the first register of Boletus luridellus (family Boletaceae) in the states of Nuevo León and Tamaulipas. Pure cultures were obtained in vitro; synthesis of mycorrhizae was achieved with Quercus fusiformis, and fruiting bodies were produced under greenhouse conditions for the first time. This species forms mycorrhizae with Quercus fusiformis, Q. polymorpha and Q. canbyi, in its natural environment. This species has a good potential for inoculation of oak seedlings in order to obtain better seedling growth under greenhouse conditions in northeastern Mexico, where oaks are currently planted in urban gardens, parks and new urban developments. This symbiosis is interesting because it occurs in a dry geographic zone where temperatures are high during the summer. Boletus luridellus is reported to be an edible species that grows well and produces sporocarps on a yearly basis (another experiment) in the gardens of the School of Forest Science in Linares, Nuevo León. Resumen Se presenta el primer registro de Boletus luridellus (Boletaceae, Boletineae) para los estados de Nuevo León y Tamaulipas, México. Se identificó la especie y se obtuvieron cultivos puros in vitro, se midió el crecimiento en dos medios de cultivo, se obtuvo la síntesis de micorrizas en plántulas de Quercus fusiformis y se regristra por primera vez la producción de esporomas de esta especie en condiciones de invernadero. En las entidades citadas, B. luridellus forma ectomicorrizas con Quercus fusiformis, Q. polymorpha y Q. canbyi, porque tiene potencial para producción de plántulas inoculadas de encino en vivero o invernadero, en el noreste de México, donde se utilizan frecuentemente para arborizar áreas urbanas, parques y nuevos fraccionamientos. Dicha simbiosis es de interés porque ocurre en una zona geográfica donde las temperaturas son altas durante el verano y el hongo puede inducir resistencia a sequía y mejorar crecimiento de las plantas. Se ha comprobado que Boletus luridellus crece bien en campo y produce esporomas cada año en los jardines del campus de la Facultad de Ciencias Forestales en Linares, Nuevo León, además se cita como comestible en la literatura especializada. Palabras clave: Boletaceae, Boletus luridellus (Murr.) Murrill, cultivo puro, producción de frutos, síntesis de micorrizas, Quercus fusiformis Small.

A new combination, Laurobasidium hachijoense, is proposed to accommodate Exobasidium hachijoense from Japan, producing aerialroot-like galls on stems of Cinnamomum japonicum. This combination is based on the presence of a gastroid-like sporulation on the surface of the galls, and is supported also by the host-plant specialization and molecular data.

Cortinarius koldingensis is described as a new species based on several collections from a small area in Denmark. Sequence data from the ITS marker places it in the Sulfurini group of the large Calochroi clade of Cortinarius subgenus Phlegmacium, along with C. sulfurinus and two North American taxa. It is phylogenetically distinct from the other species in the Sulfurini and differs from C. sulfurinus by several deviating morphological characteristics. The species has been collected on several occasions over the last 15 years from only one Danish locality. Despite extensive molecular screening of numerous possible conspecific specimens, including holotype and comparison with all publicly available ITS sequence data from specimens and environmental DNA alike, no match with specimens from elsewhere has been encountered, and we hypothesize that the species is rare in Europe.

Coltriciella sonorensis is described here as a new species from Mexico. It is characterized by pleuropodal, flabelliform basidiomes, rounded to elongated or daedaloid pores, a well-developed sub-hymenium, and oblong to cylindrical basidiospores, slightly attenuated towards the apex. The specimen was collected on soil in an open Quercus stand in mixed Quercus–tropical deciduous forest in the Sierra de Álamos–Río Cuchujaqui Biosphere Reserve, Sonora, Mexico. From a phylogenetic perspective, the species appears to be related to C. oblectabilis, also occurring in Mexico.
