If Nair and Kaul (1980) were correct in their identification of the basidiocarps as P. gemmellarii and if P. gemmellarii is not conspecific with P. cystidosus, then A. macrocarpa is a species aggregate. If P. gemmellarii is conspecific with P. cystidiosus, it is the correct name of the species.
Stilbum macrocarpum
Pleurotus cystidiosus
