Studies on Persoon’s original material of Clavariaceae deposited at the Nationaal Herbarium Nederland, Leiden

Adamčík S. (2008): Studies on Persoon’s original material of Clavariaceae.

Sydowia 61 (2): 191–207

Twenty specimens of expected members of Clavariaceae from Persoon’s herbarium in Leiden were studied. Only observations on specimens of Clavaria pratensis agree with recent treatment of the species as synonym of Ramariopsis corniculata. Specimens of C. helvola and C. eburnea represent various taxa, but some of them are also representatives of these names in recent concept. The single specimen of C. furcata, a species synonymised recently with Ramariopsis corniculata, is probably identical with Ramaria stricta. The single specimen of C. pistilliforma represent a taxon related to C. argillacea, and it is not identical with C. vermicularis as suggested in literature. Specimens of C. alba and C. vitellina were infected by parasitic fungi and their collapsed microscopical structures does not allow any interpretation. Most of the specimens were collected in the last period of Persoon’s active research of fungi and none of them should be connected with protologue and used as a type.

Keywords: Clavaria, Ramariopsis, taxonomy, type studies.
