Penicillifer diparietisporus: a New Record from Field Soil in Korea
A fungus was isolated from field soil collected from Daegu, Korea. The colony of the isolated fungus showed short, branched, and light to dark yellow pigments with hyaline, yellowish red to orange brown aerial mycelia. In addition, the fungus produced solitary to aggregated perithecia, ovoid to pyriform, short neck, and asci as well as biseriately arranged ascospores. Phylogenetic analysis using the internal transcribed spacer region and translation elongation factor 1-α sequences and morphological characteristics identified the isolated fungus as Penicillifer diparietisporus, which belongs to the family Nectriaceae. To our knowledge, this is the first report of Penicillifer diparietisporus in Korea.
Identification and nomenclature of the genus Penicillium
Studies in Mycology, 2014
Penicillium is a diverse genus occurring worldwide and its species play important roles as decomposers of organic materials and cause destructive rots in the food industry where they produce a wide range of mycotoxins. Other species are considered enzyme factories or are common indoor air allergens. Although DNA sequences are essential for robust identification of Penicillium species, there is currently no comprehensive, verified reference database for the genus. To coincide with the move to one fungus one name in the International Code of Nomenclature for algae, fungi and plants, the generic concept of Penicillium was re-defined to accommodate species from other genera, such as Chromocleista, Eladia, Eupenicillium, Torulomyces and Thysanophora, which together comprise a large monophyletic clade. As a result of this, and the many new species described in recent years, it was necessary to update the list of accepted species in Penicillium. The genus currently contains 354 accepted species, including new combinations for Aspergillus crystallinus, A. malodoratus and A. paradoxus, which belong to Penicillium section Paradoxa. To add to the taxonomic value of the list, we also provide information on each accepted species MycoBank number, living ex-type strains and provide GenBank accession numbers to ITS, β-tubulin, calmodulin and RPB2 sequences, thereby supplying a verified set of sequences for each species of the genus. In addition to the nomenclatural list, we recommend a standard working method for species descriptions and identifications to be adopted by laboratories working on this genus.

Ninety six samples of water collected from Dal Lake, Kashmir at eight different sites for a period of one year from April 2010 to March 2011 were tested for the presence of Penicillium species. Five different species of the said genus were isolated from the samples by serial dilution technique. Out of total 122 fungal colonies isolated, five species of Penicillium viz, Penicillium olivicolor, Penicillium commune, Penicillium chrysogenum, Penicillium funiculosum and Penicillium dimorphosporum were obtained. Among the isolated species P. funiculosum was the most abundant (28.7%) followed by P. chrysogenum (27.04%), P. dimorphosporum (23.77%), P. olivicolor (16.40%) and P. commune (4.09%). Maximum percentage of fungal colonies (27.7%) was observed at site PKB followed by TBN (21.13%), DLG and GB (13.15%) each, NL (8.45%), BHN (7.04%), HB (5.63%) and BD (3.76%).

Three new species of penicillium
Mycopathologia, 1978
Three new species of microfungi belonging to the genus Penicillium Link ex Fries are described and illustrated. All but one have been isolated from the atmosphere of las Palmas, capital city of the island of Gran Canaria (Canary Islands, Spain). They clearly differ from all species of the genus described so far and are, therefore, described and proposed as new species: Penicillium hispanieum sp. nov., Penicillium grancanariae sp. nov., and Penicillium palmensis sp. nov.
Seven new species of Penicillium and a new variety of Penicillium novae-caledoniae Smith
Mycopathologia, 1981
Seven new species of Penicillium Link ex Fries and a new variety of Penicillium novae-caledoniae Smith are described and illustrated. Four of them have been recovered from the air in Madrid, Spain, one from beech leaves litter in a beech forest near Nancy, France, two from sandy soils in Madrid, and one from an andosol in the Spanish Province of Navarra. They clearly differ from all species of the genus described so far and are, therefore, described and proposed as new taxa:
A taxonomic study of the Penicillium chrysogenum series
Antonie van Leeuwenhoek, 1977
The taxonomy of the Penicillium chrysogenum series is reconsidered. On account of the observations of the available type strains and numerous isolates mainly obtained from food products, Penicillium notatum Westling, P. meleagrinum Biourge and P. cyaneofulvum Biourge are placed in synonymy with P. chrysogenum Thom. Synonymy and variability of the species are discussed.
Systematic and Applied Microbiology, 1990
This first study by the Subcommission on Penicillium and Aspergillus Systematics is concerned with the status of the closely related species Penicillium glabrum, P. spinulosum, P. purpurescens, and P. montanense. Thirty five isolates tentatively identified as these species were studied as unknowns by the eight members of the Subcommission. Characters studied included traditional morphology and gross physiology plus secondary metabolite profiles, isoenzyme patterns and DNA restriction enzyme fragment length polymorphism. The various approaches provided consistent identifications for most isolates, indicating that the four species could be separated satisfactorily and should be maintained. Statistical models based on morphological and gross physiological data indicated that five characters were of value in distinguishing the species. These were conidial wall texture, colony diameters on Czapek yeast extract agar and 25% glycerol nitrate agar, phialide width and vesicle diameter. Practical aspects of differentiating these species are also discussed.

Several species of the genus Penicillium were isolated during a survey of the mycobiota of leaf litter and soil in Colombian Amazon forest. Five species, Penicillium penarojense sp. nov. (type strain CBS 113178(T) = IBT 23262(T)), Penicillium wotroi sp. nov. (type strain CBS 118171(T) = IBT 23253(T)), Penicillium araracuarense sp. nov. (type strain CBS 113149(T) = IBT 23247(T)), Penicillium elleniae sp. nov. (type strain CBS 118135(T) = IBT 23229(T)) and Penicillium vanderhammenii sp. nov. (type strain CBS 126216(T) = IBT 23203(T)) are described here as novel species. Their taxonomic novelty was determined using a polyphasic approach, combining phenotypic, molecular (ITS and partial β-tubulin sequences) and extrolite data. Phylogenetic analyses showed that each novel species formed a unique clade for both loci analysed and that they were most closely related to Penicillium simplicissimum, Penicillium janthinellum, Penicillium daleae and Penicillium brasilianum. An overview of the phylogeny of this taxonomically difficult group is presented, and 33 species are accepted. Each of the five novel species had a unique extrolite profile of known and uncharacterized metabolites and various compounds, such as penicillic acid, andrastin A, pulvilloric acid, paxillin, paspaline and janthitrem, were commonly produced by these phylogenetically related species. The novel species had a high growth rate on agar media, but could be distinguished from each other by several macro- and microscopical characteristics.
