Two lignicolous species of Agaricales, viz. Mycena renati Quél. and M. viridimarginata P. Karst., are discussed. In addition to the description, ecology and distribution in Czechoslovakia, results referring to the taxonomic position of M. luteoalcalina Sing. are also mentioned. Based on the authors’ study of the Singer’s type specimen, the species was identified with M. renati Quél. Thus the name M. luteoalcalina Sing. sensu Kühner is considered to be synonymous with M. viridimarginata P. Karst. The name M. alcalina (Fr.) Kumm. is proposed by the present authors to be rejected and listed as a rejected name in “Nomina rejicienda”.
