Cyathus species (Basidiomycota: Fungi) from the Atlantic Forest of Pernambuco, Brazil: taxonomy and ecological notes

Cyathus specimens were collected over a one-year period in 4 remnants of the Atlantic Forest in Pernambuco, Brazil. According to traditional morphological analysis, the following species were identified: C. intermedius, C. montagnei, C. setosus and C. triplex. These 4 species had previously been recorded from Brazil, but C. setosus is reported for the first time from northeastern Brazil. The holotype of C. setosus was examined and we found differences in the spore dimensions from those described in the original publication. An identification key for the species of Cyathus recorded from Pernambuco is provided.
