A macro-microscopic and enzymatic characterization of six mycelial strains of Mycena, from pure cultures of the corresponding basidiocarps is given. The studied strains were UACHMMa-464, UACHMMc-495, UACHMMg-250, UACHMMm-302, UACHMMp-354 and UACHMMr-260. Their isolation in pure culture, their growth in the culture media PDA, MEA, CzA, and some hyphal structures are discussed. A marked presence of enzymes involved in the degradation of the ligno-cellulose complex was detected. This could be an indication of a certain specificity or specialization in the degradative processes of these fungi in nature.
