| Abstract: | As shown by morphological and molecular (ITS, nrLSU and tef1 sequences) evidence, the current concept of Myxarium nucleatum covers four species in the Nordic countries: M. cinnamomescens, M. hyalinum, M. nucleatum s.s. and M. populinum. These species are redescribed here, their nomenclature is discussed and all relevant names are typified. Exidia cartilaginea and E. villosa are typified and shown to be conspecific with the North American species E. candida. Based on morphological differences, E. cartilaginea is retained as a variety of E. candida. Exidia subrepanda is treated as a synomym of E. saccharina, and Heterochaete europaea as a synomym of E. thuretiana. |
