From: Diversity of Chroogomphus (Gomphidiaceae, Boletales) in Europe, and typification of C. rutilus
Basidiospores of Chroogomphus species: A. C. rutilus (K(M)198589). B. C. cf. purpurascens (K(M)233762). C. C. mediterraneus (K(M)233761). D. C. britannicus (H6045578). E. C. fulmineus (LIP 0401320). F. C. subfulmineus (LIP 0401318, holotype, with unusually broad spores). G. C. subfulmineus (UDB001529). H. C. cf. helveticus (H7019100). The degree of spore dextrinoidity does not appear to be a consistent characterwithin species. Bar = 20 µm. Photographs: Ross Scambler.
