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

Abstract

Gymnopilus is characterized by its ferruginous-yellow basidiomata and lamellae, ferruginous spore print, ellipsoidal basidiospores with warty and rough ornamentation, and lacking a germinative pore. Here, novel data on the Gymnopilus species of Paraguay is presented, macro and microscopic morphological characteristics, distribution, and ecology are described, and a taxonomic discussion is provided. Gymnopilus imperialis is recorded in the Alto Paraná Department, G. lepidotus in the Central Department, G. luteofolius in the Cordillera Department, G. peliolepis in the Paraguarí Department, and G. purpureosquamulosus in the Central Department and Boquerón, all as new records for Paraguay. Photographs of the fresh basidiomata and some microscopic structures such as basidia and basidiospores are attached.

Immunomodulatory Effect of Polysaccharides from the Mushroom-Forming Basidiomycete Gymnopilus imperialis (Agaricomycetes, Basidiomycota)

“…The wild mushrooms studied were collected in April 2016 in an Atlantic Rainforest remnant in Southeastern Brazil (Iporanga, São Paulo: S24°33.51′, W48°43.54′, elevation 500–530 m). The morphological data used for taxonomy were based on notations from fresh and dried basidiomata and compared to previous descriptions [ 48 , 49 ]. The remaining basidiomata were deposited at Herbarium SP at the ‘Instituto de Pesquisas Ambientais’ (IPA, Saão Paulo, SP, Brazil) under the number SP513080.…”

“…A single dataset was generated from alignment conducted in MAFFT 7 ( (accessed on 25 July 2022)) [ 52 ] with auto strategy, and including 91 sequences of Gymnopilus species, most of them previously generated [ 1 , 7 , 8 ] and recovered from a BLASTn search ( (accessed on 25 July 2022)) against the NCBI GenBank database based on the newly generated sequence in this study. Additionally, an ITS sequence from an authentic G. imperialis from Paraguay [ 48 ] was kindly provided by M.G. Campi for comparison and then deposited at GenBank under the accession code OP094030.…”
