Barcoding and Morphological Characterization of Mycena cupressina (Agaricales, Fungi), a Little-known and Controversially Treated Member of Section Supinae

The author presents recent collections of Mycena cupressina, a corticolous species on Cupressus sempervirens, described from the Mediterranean area and sometimes treated as conspecific with M. juniperina. first ITS nrDNA sequence Balkan material was obtained. Its analysis demonstrated affinity sequenced collection to section Supinae, although results could not be unambiguously interpreted suggest that in this marker may less informative, similarly some other groupings genus. Description cupressina is provided, based collections. studied Cupressus-affiliated specimens share smooth stipitipellis hyphae, deemed diagnostic character species, suggesting for time being two are better retained separate taxa. records Bulgaria four section, namely juniperina, meliigena, pseudocorticola supina, also included.
