Fungal biodiversity profiles 21–30

The authors describe ten new taxa for science using mostly both morphological and molecular data. In Basidiomycota, descriptions are provided for Botryobasidium fusisporum sp. nov., B. triangulosporum sp. nov., Cantharellus hydnoides sp. nov. and Hydnum aerostatisporum sp. nov. in Cantharellales; Lactarius rahjamalensis sp. nov. and Russula pseudoaurantiophylla sp. nov. in Russulales and for Mycena paraguayensis comb. nov. in Agaricales. In Ascomycota and hyphomycetes, descriptions are provided for Colletotrichurn eryngiicola sp. nov. (Glomerellales), Corynesporella indica sp. nov. (incertae sedis) and Repetophragma zygopetali sp. nov. (Microthyriales)

Thelephora sikkimensis sp. nov. (Thelephoraceae) from the Eastern Himalayas (India)

Thelephoroid fungi are abundant ectotrophic symbionts in temperate forests worldwide.The state of Sikkim, in India, constitutes a hot spot of fungal diversity due to the occurrence ofmany ectomycorrhizal tree species. Collections of a stipitate thelephoroid species were found underCastanopsis hystrix in the district South of this state. Molecular and morphological analyses supportthe placement of these collections as a monophyletic unit that is proposed here as Thelephorasikkimensis sp. nov. This species is characterized by its pileate-stipitate basidiomes; zonate-hairypileus surface, papillate-odontoid hymenophore and large basidia [35?65 (infrequently up to 125)× 7-9 μm]. Morphological details of this new species are presented along with its phylogeneticaffinities estimated on nrITS-based analyses.Fil: Das, Kanad.
