Data from: Morphological and phylogenetic evidences unveil a novel species of Gyroporus (Gyroporaceae, Boletales) from Indian Himalaya
Repeated macrofungal forays to East district of Sikkim followed by morphological and phylogenetic studies of collected wild mushrooms revealed an undescribed species, proposed here as Gyroporus paramjitii. This species is featured with hemispheric to plane dark brown to brownish orange pileus, concolorous or darker stipe, snow white to pale yellow pore surface which is immutable when bruised, 2- to 4-spored basidia, reniform to elliptic basidiospores, presence of pleurocystidia and cheilocystidia, absence of caulocystidia, trichoderm pattern of pileipellis and stipitipellis with encrusted erect hyphal elements and occurrence under Castanopsis sp. Macro- and micromorphological details coupled with phylogenetic analyses (based on nrITS and nrLSU data) are presented for this taxon
Gliophorus glutinosus sp. nov. (Hygrophoraceae, Agaricales) from Eastern Himalayan region of India
An interesting species of the genus Gliophorus (sect. Glutinosae), collected from Sikkim Himalaya in India, is described here as G. glutinosus sp. nov. after thorough morphological examination and phylogenetic analysis. The species is mainly characterised by its strongly glutinous basidiomata throughout, particularly on the twisted stipe, decurrent lamellae with glutinous edge, gelatinised cheilocystidia, presence of pleuropseudocystidia and absence of clamps in hyphae of the pileipellis. This communication includes detailed morphological description, illustrations, comparison with the allied taxa, nrITS based phylogeny of this novel taxon and a key to the species under Gliophorus sect. Glutinosae

First records of Tylopilus glutinosus Iqbal Hosen (Boletaceae) from Shorea robusta-dominated forests in tropical India: morphological description and phylogenetic estimation
During the routine survey for exploring the hidden macrofungal wealth of tropical Sal (Shorea robusta Roth) forests in West Bengal and Jharkhand (India), we found a specimen similar to Tylopilus plumbeoviolaceous (Snell & E.A.Dick) Snell & E.A.Dick. After careful morphological observations and phylogenetic analysis, the species was found to be conspecific with Tylopilus glutinosus Iqbal Hosen, a recently established taxon from Bangladesh. We report T. glutinosus for the first time from India and provide a detailed description, figures, a multigene phylogenetic analysis, and comprehensive comparisons with similar species. A distributional map is also provided

Morphological and phylogenetic evidence for two new Lactarius species (Russulales, Basidiomycota) from India
Lactarius ferruginascens sp. nov. and L. indoaquosus sp. nov. are described from the East and South districts of Sikkim, a small Himalayan state in India. Macro- and micromorphological descriptions coupled with the illustrations and nrITS-based molecular analyses are given for both species. Lactarius ferruginascens is a species in L. subg. Plinthogalus with striking features such as a sticky pileus surface caused by the ixohymeniderm structure of the pileipellis, watery white latex which is turning rusty brown on the lamellae and the occurrence under Abies sp. in the subalpine mixed forest. Lactarius indoaquosus is a new representative of L. subg. Russularia with completely transparent and unchanging latex and is furthermore characterized by basidiospores with a zebroid ornamentation, the absence of hymenial macrocystidia and the occurrence under Castanopsis sp. in the temperate broadleaf forest. Both species are illustrated and compared with related taxa
