Gymnopilus purpureosquamulosus Høil. (Agaricales, Basidiomycota): a new distributional record from India

Abstract

Abstract:Gymnopilus purpureosquamulosus Høil (Strophari aceae) is reported for first time from India. A comprehensive description, a photograph, and comparisons with morphologically similar and phylogenetically related species are provided.

Five New Species of Gymnopilus from Xizang Autonomous Region of China and Surrounding Areas

“…Gymnopilus dilepis can differ by its convex to plano-convex pileus with ruby to violet brown squamules, bigger basidiospores (6–7.5 × 4.8–6 µm), shorter and thicker cheilocystidia (20–30.2 × 8–12 µm) [ 12 , 42 ]. Gymnopilus purpureosquamulosus differs in having brown–purple to purple pileus with a central depression, a surface covered with reddish violet squamules and lamellae that turn grey with KOH and FeSO 4 , and bigger basidiospores (7–8 × 4–5.5 µm) [ 18 ]. Gymnopilus dunensis can differ by its pileus, covered with greyish squamules when young; bigger basidiospores (8.5–10.7 × 4.9–6.6 μm) and basidia (24.9–29.4 × 8.5–9.7 μm); and the fact that it is gregarious in small groups on sandy soil [ 19 ].…”

“…Later, Guzmán-Dávalos (1995) established a section, Macrospori Guzm.-Dáv (1995: 119) to Gymnopilus , which contains species characterized by large spores and a lack of an annulus [ 7 , 11 ]. Recently, morphological examination combined with molecular phylogenetic analysis has been widely used to study this genus and describe new species from different parts of the world [ 2 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ].…”

“…The alignment obtained to explore the phylogenetic relationships of the new species of Gymnopilus was based on the taxonomic sampling employed by [52,53] (Table 2). The ITS region was aligned using the online version of MAFFT v. 7 [54][55][56].…”

First contribution to the genus Gymnopilus (Agaricales, Strophariaceae) in Paraguay

“…The species have pantropical distribution. Zimbabwe (Høiland 1998), Nigeria, Italy, Switerland, Panama (Guzmán-Dávalos et al 2003, India (Acharya et al 2017) and Brazil .…”

“…Gymnopilus purpureosquamulosus is characterized by having the pileus covered with pointed and erect scales in the center, adpressed towards the margin, reddish, lilac, reddish brown when fresh, and purple when dry, ellipsoidal to oblong basidiospores, with subacute apex, the cheilocystidia of varied forms, lageniform, utriform, cylindrical to fusiform, with claviform, rounded to globose apex. (Høiland 1998;Guzmán-Dávalos et al 2008;Acharya et al 2017). Høiland (1998) indicates that G. peliolepis (Speg.)…”
