Original Article


Three species currently addressed to Protohydnum (Auriculariales) are studied with morphological and DNA methods. The genus Protohydnum is retained for the type species only, P. cartilagineum, recently re-collected in Brazil. The European species, P. piceicola, is not congeneric with P. cartilagineum and, therefore, placed in its own genus, Hyalodon, gen. nov. Another Hyalodon species, H. antui, is described from East Asia. The third member of Protohydnum sensu lato, P. sclerodontium from South-East Asia, is transferred to Elmerina.

We thank Herbarium of Andalas University, Sabah Parks, BORNEENSIS (Universiti Malaysia Sabah), and Sabah Biodiversity Council for their assistance to conduct field work (permit to the author JSSS). We thank Mr. Rolinus Paulus for helping at the fieldwork in Sabah. Ricardo M. Pires (Instituto de Botânica, São Paulo) kindly provided us with the specimen of P. cartilagineum and Tuomo Niemelä (University of Helsinki) with the specimen of Hyalodon antui. Alexander Sennikov (University of Helsinki) advised us about nomenclatural problems.
