Exidia
''Exidia'' is a genus of fungi in the family Auriculariaceae. Species are saprotrophic, growing on dead attached or recently fallen wood, and produce gelatinous basidiocarps (fruit bodies). The fruit bodies are variously pustular, lobed, button-shaped, or top-shaped. Several species, including the type species ''Exidia glandulosa'', have sterile pegs or pimples on their spore-bearing surface. Others are smooth. The genus has a cosmopolitan distribution and around 20 species are currently recognized worldwide. Initial molecular research indicates the genus is artificial.〔Weiss, M & Oberwinkler, F. (2001). Phylogenetic relationships in ''Auriculariales'' and related groups – hypotheses derived from nuclear ribosomal DNA sequences. ''Mycological Research'' 105: 403–415.〕
==Taxonomy==
Species were originally placed in the genus ''Tremella'' along with many other gelatinous fungi. The genus ''Exidia'' was separated from ''Tremella'' by Fries in 1822, based mainly on fruitbody shape. Fries initially included species now assigned to ''Auricularia'' within the genus.
Recent molecular research has indicated that ''Exidia'' as currently circumscribed is an artificial grouping, species not being clearly differentiated from similar, but effused species assigned to the genera ''Exidiopsis'' and ''Heterochaete''.〔 Only a few species have yet been sequenced, however.
