Index Fungorum number: IF 17291; MycoBank number: MB 17291
Chlorophyllum (Agaricaceae, Agaricales) was introduced by Massee (1898) with C. molybdites (G. Mey.) Massee as the type species. Chlorophyllum species are widely distributed in tropical, subtropical, and temperate areas throughout the world as saprobes (Ge and Yang 2006; Kirk et al. 2008; Crous et al. 2015a, b, c; Ge et al. 2018; Dutta et al. 2020). This genus is characterized by agaricoid, secotioid or sequestrate habits, a hymenidermal pileus covering and smooth stipe, white, green or brown basidiospores either lacking a germ pore or with a germ pore that is caused by a depression in the episporium (Ge
and Yang 2006; Vellinga 2002, 2003a, 2004; Crous et al. 2015a, b, c; Loizides et al. 2020). Most Chlorophyllum species are known to be poisonous (Vellinga and de Kok 2002; Leudang et al. 2017). There are 28 accepted species of Chlorophyllum in Index Fungorum (2022a, b). Chlorophyllum is divided into six infrageneric sections: Chlorophyllum Massee, Ellipsoidospororum Z.W. Ge, Endoptychorum (Czern.) Z.W. Ge, Parvispororum Z.W. Ge, Rhacodium Z.W. Ge and Sphaerospororum Z.W. Ge based on morphological and phylogenetic analyses (Ge et al. 2018). Only four Chlorophyllum species, C. globosum (Mossebo) Vellinga, C. hortense (Murrill) Vellinga, C. molybdites (G. Mey.) Massee and C. rhacodes (Vittad.) Vellinga, have been reported from Thailand (Chandrasrikul et al. 2011; Leudang et al. 2017; Ge et al. 2018; Sysouphanthong et al. 2021; Suwannarach et al. 2022).
