Revision of the genera Agrocybe and Cyclocybe (Strophariaceae, Agaricales, Basidiomycota) in Argentina

Agrocybe is characterized by the collybioid to tricholomatoid basidiomata with rusty to dark spore-print, a hymeniform pileipellis, and basidiosspores with a reduced to broad germ-pore. Recently, the species with reduced germ-pore were segregated to Cyclocybe. The knowledge of these genera in Argent...

Recently, the species with reduced germ-pore were segregated to Cyclocybe. The knowledge of these genera in Argentina is scanty, although they have been partially studied in the country, but there is not a field that deals exhaustively with it. Macro- and micromorphological characters of specimens obtained in the feld and from different national herbaria (BAFC, CTES, LIL, LPS) were analyzed. Cultivation techniques were used to obtain basidiomata, allowing for a macro- and micromorphological study of fresh developing basidiomes. We concluded that in Argentina there are, so far, 14 species of Agrocybe (one of them with 3 varieties) and two of Cyclocybe including to C. wrightii, which is proposed as a new combination. Sixteen species are described and a key to the Argentinian species of Agrocybe and Cyclocybe is proposed. Agrocybe se caracteriza por sus basidiomas collibiodes a tricholomatoides, esporada con coloraciones ferrugineas a oscuras, pileipellis himeniforme y esporas con poro germinativo. Recientemente, las especies con poro germinativo reducido fueron segregadas a Cyclocybe. El conocimiento de estos géneros en Argentina es escaso, aunque hay estudios parciales de varios micólogos, no hay un trabajo que lo trate exhaustivamente en forma conjunta. Se analizaron caracteres macro y micromorfológicos de especímenes colectados y de diferentes herbarios nacionales (BAFC, CTES, LIL, LPS). Se utilizaron técnicas de cultivo para obtener basidiomas, lo que permitió un estudio macro y micromorfológico de material fresco en desarrollo. Concluimos que en Argentina hay, hasta el momento, 14 especies de Agrocybe (una de ellas con tres variedades), y dos especies de Cyclocybe, incluyendo a C. wrightii, la cual es propuesta como una nueva combinación. Se describen dieciséis especies y se propone una clave para las especies argentinas de Agrocybe y Cyclocybe. 2025-12-05T11:11:36Z 2025-12-05T11:11:36Z 2020 Artículo Niveiro, Nicolás, Uhart, Marina y Albertó, Edgardo Omar, 2020.
