A New Lichenicolous Fungus from Garhwal Himalayan Region of Uttarakhand, India

Acta Botanica Hungarica, 2021

Sphinctrina pertusa Falswal A. is described as a new species of lichenicolous fungus from India. It is characterised by eight non-septate, broadly ellipsoidal, uniseriate, ascospores with olive green tint and irregular ridge like ornamentations. This fungus is growing on known lichen host Pertusaria but differs from five closely related species i.e., S. anglica, S. leucopoda, S. tubaeformis, S. turbinata, S. paramerae with different taxonomic characters. A detailed comparative analysis with non-septate closely related species is provided.

New Records of Lichen Taxa from the State of Kerala, India

Cryptogam Biodiversity and Assessment, 2022

The present paper deals with 11 new records of lichens under 7 genera and 6 families, for the state of Kerala in India. The species are Bacidia personata, Chrysothrix chlorina, Cryptothecia candida, Cryptothecia emergens, Cryptothecia nilghiriensis, Letrouitia aureola, Ochrolechia africana, Pertusaria coronata, P. quassiae, P. subdepressa, and Phyllopsora manipurensis. Brief descriptions of these taxa were provided to facilitate their identification.

Lichen-forming and lichenicolous fungi of the Western Ghats, India

The biota of lichen-forming and lichenicolous fungi occurring in the Western Ghats were analyzed utilizing recent publications. The study revealed the occurrence of 1617 taxa of lichen-forming fungi (or lichens) with 1597 species, 19 varieties, 2 subspecies, 1 forma. The lichenicolous fungi were represented by 28 species. As the lichenicolous fungi are fewer in number and unexplored groups, the emphasis is given to lichens in the present communication. A total of 251 lichen taxa are endemic, of which, 129 are restricted in their distribution to the Western Ghats only. The lichen biota of Western Ghats is dominated by crustose lichens with 1117 taxa while foliose and fruticose forms represent 393 and 107 taxa. All the lichens taxa reported belonged to phylum Ascomycota and are dominated by Graphidales and pyrenocarpous lichens with 404 and 224 taxa, respectively. Graphis, Graphidaceae, Lecanorales and Lecanoromycetes are the most speciose genus, family, order and class in the region with 78, 210, 421, and 1288 taxa, respectively. As many as 1231 lichens in the region preferred to grow on bark only while 50 taxa shared substrates such as bark, rock, and soil. This region also represented a good diversity of cyanolichens (117) which are known indicators of moistness in the forests. Similarly, a study indicated that some parts of the Western Ghats are healthy and undisturbed by the presence of 88 foliicolous lichens. Several species of lichens are rare in the Western Ghats, and among them, at least five of them are not collected for a long time and are suitable for inclusion in the Red Data Book. Among different states, Tamil Nadu, Kerala, and Karnataka represent maximum number of lichens represented by 963, 783, and 658 taxa, respectively. The lichens of Western Ghats show their affinities to the lichen biota of northeastern India and

Additions to the bibliography of Indian lichens in the years 2018 and 2019

Cryptogam Biodiversity and Assessment , 2020

This communication is in continuation with "Bibliography to the Indian lichens from the year 2010 onwards" published in a special volume of this journal by Joseph et al. (2018). Here a total of 146 research articles, books and chapters published during the years 2018 and 2019 are listed. The list also includes some of the references missing in the previous list. It is interesting to note that the range of publications during this period included all aspects of lichenology, starting from taxonomy to bioprospecting and lichenized fungi to endolichen and lichenicolous fungi. The missing publications, if any, in this list will be included in the forthcoming volume of the journal.

An enumeration of lichens from the Bageshwar district of Kumaun Himalaya, Uttarakhand, India

The paper, lists 361 species of lichens belonging to 89 genera and 35 families from the Bageshwar district of Uttarakhand. The study is based on the published literature and specimens in the herbarium of National Botanical Research Institute, Lucknow (LWG). Dhakuri and Khati areas, situated between 2683 2210 m have the highest diversity of lichens represented by 215 and 172 species, respectively. Lichen, families Parmeliaceae with 23 genera and Physciaceae with 8 genera are the dominant families in the district. Among the different lichen genera, Cladonia with 22 species and Heterodermia with 18 species exhibit their dominance in the area. Trees bear a luxuriant growth of lichens and particularly Quercus, Pinus, Alnus and Cedrus exhibit the maximum diversity of epiphytic lichens in the district.

The newly reported species from Assam are Alyxoria apomelaena, A. culmigena, A. varia, Caloplaca pseudisteroides, Cryptothecia striata, Diorygma rupicola, Dirinaria papillulifera, Flavoplaca citrina, Graphis sundarbanensis, Herpothallon echinatum, Lecanographa rufa, Letrouitia muralis, Myriotrema clandestinum, Opegrapha discolor, Parmotrema crinitoides, Phaeophyscia hispidula, Porina eminentior, P. interstes, P. mastoidella, Pyrenula submastophora, P. thelomorpha, Rinodina oxydata, Synarthonia bicolor, Zwackhia bonplandii, and Z. viridis. Brief descriptions of these additional lichen taxa from Assam are provided to facilitate their identification.

New addition to the Lichen flora of Uttarakhand, India

2016

The present paper revealed the occurrence of nine lichen species from Uttarakhand for the first time. The species belong to six families (Cladoniaceae, Lecanoraceae, Parmeliaceae, Peltigeraceae, Physciaceae, Verrucariaceae) and represents four growth forms of lichens found growing on soil, rock and soil over rock. Brief moropho-taxonomic details of all the nine species have been provided with their ecology and distribution.
