Remarks (internal):I. hamusetulus is related to I. radiatus (Fr.) Karst. and I. crocitinctus (Berk. & Curt.) Ryv. All three species are characterized by hooked setae and small, hyaline to pale yellowish subglobose spores. The spore-range decreases from I. radiatus to I. hamusetulus. The closest relative to I. hamusetulus is the North American I. crocitinctus which has slightly larger spores (4-4,5 x 3-3,5 µm) , distinctly more ventricose setae and minute pores (7-8 per mm) .
