Gymnopilus pholiotoides (Agaricales, Basidiomycota), um novo registro inesperado em uma área urbana no Brasil

Abstract

Gymnopilus pholiotoides Murrill is discovered for the first time from Brazil. The Brazilian specimen is characterized by the orange tones then yellowish cream color in older basidiomes, pileus surface cracking into areolate appressed squamules when mature, presence of a fragile membranous pendant annulus, basidiospores (7.1-) 7.6-9.2 (-9.7) × 4.6-5.6 µm, absence of pleurocystidia, and presence of scattered caulocystidia. Description, discussion, drawings, and photographs of the sample are provided. Furthermore, a comparison with the type specimen of G. pholiotoides was made.

“…Gymnopilus P. Karst. is a genus of mostly lignicolous agaricoid mushrooms with about 200 mainly lignicolous species (He et al 2019;Wijayawardene et al 2020), of which 23 are known in Brazil (Fabrini & Wartchow 2020;Fabrini et al 2022). From the Amazon region, the following Gymnopilus taxa were reported: G. marasmioides (Berk.)…”

“…Following our investigations of Gymnopilus in Brazil (e.g., Silva-Junior & Wartchow 2015;Fabrini & Wartchow 2020;Fabrini et al 2022), we begun to analyze exsiccates of Gymnopilus included in the unpublished thesis made by Aguiar (1984) and deposited in the INPA Herbarium (Thiers, continuously updated). One of them corresponds to an interesting material provisionally named as "Gymnopilus violaceus I.J.…”
