= Pholiota baeosperma Singer , Sydowia 7: 217, 1953. Fide Horak (1967).

Neotype (designated here): — ARGENTINA, Tierra del Fuego: Est. Nueva Argentina , ad terram in silvis sub Nothofago antarctica , 11 Feb. 1950, leg. R. Singer M 180 ( LIL!).

Distribution and ecology:— Growing on humus of Andino-Patagonic forest from South America, from Tierra del Fuego to Neuquén provinces ( Spegazzini 1887a, Singer 1952, Singer & Digilio 1952, Niveiro & Albertó 2012 b) ( Fig. 4 View FIGURE 4 ).

Additional specimens examined:— ARGENTINA, Tierra del Fuego: Est. Nueva Argentina, in silvis nothofaginensis ( N. antarctica ) inter gramina ad terram, 16 Feb. 1950, R. Singer M 307 (LIL!) , Neuquén: Nahuel Huapi National Park, trail to Los Cántaros, on woody humus in woods, 16 Feb. 1960, R. Singer M 3019 (LIL!), Ib . Nahuel Huapi lake , Pto. Blest, in Nothofagus -Saxegothaea woods among herbaceous plants, on humus, 16 Feb. 1960, R. Singer M 3008 (LIL!) .

Remarks: The type material of P. subflammans deposited in LPS herbarium and originally described by Spegazzini (1887a) is lost (Chayle, pers. comm.). Horak (1967: 358), who reanalyzed the type material of P. subflammans , noted that the type specimen consisted of remnants in poor condition. For this reason, a collection made by Singer in 1950 and described in Singer (1952: 497) which is in good condition and was collected in the Estancia Nueva Argentina ( Tierra del Fuego province), (the same place where the original collection was made by Spegazzini) is proposed as the neotype of this species.

A complete description of this species was realized by Singer (1952: 497) as P. subflammans , and Singer (1953: 217) and Singer & Digilio (1952: 339) as P. baeosperma Singer.

Pholiota baeosperma Singer was included in section Lubricae (Fr.) Singer because it does not have scales on the pileus surface ( Singer 1953: 217, Singer & Digilio 1952: 339). However, according to Horak (1967: 358) the latter is synonymous with P. subflammans , having lost the scales by the action of rain or high atmospheric humidity. As a consequence, the pileipellis hyphae walls become gelatinous and the scales are lost, as was also observed in P. kauffmaniana A. H. Sm. and P. flammans in the Northern Hemisphere ( Smith & Hesler 1968).
