Noves dades sobre el component fúngic de les comunitats de Cistus de Catalunya, II

Abstract

In this new contribution, 64 species of fungi associated with Cistus are described, discussed or simply quoted; 40 of them are new additions to the mycota of the Mediterranean rockrose bush tCistion) communities. A number of drawings of microscopic characters and colour photographs showing the habit are given. Provisional identification keys are proposed for the species of: Entoloma, Gymnopus and other collybioid taxa , Lepiota and Lyophyllum, found by the authors under Cistus. Sorne of the species mentioned are of special interest: Clitocybe agrestis, C. augeana, Clitocybula taniae, Entoloma cf. cruentatum, E. lucidum, Gymnopus pubipes, Hemimycena conidiogena, Laccaria proxima f. mediterranea, Lyophyllum lanzonii, L. striaepileum, Marasmiellus carneopallidus, Melanoleuca friesii and Pseudoomphalina pachyphylla. Four new taxa are described: Entoloma sericeum varo minutisporum, Lyophyllum cistophilum, L. phaeophyllum and Omphalina tabaresiana, and five new nomenclatural combinations are proposed: Gymnopus bisporus, G. catalonicus,G. impudicus varo graveolens, G. inusitatusand G. lanipes. After the study of an Italian collection, the name Cortinarius aureocistophilus, previously described ad interim (2002) , is validated. A provisional description of a Lepiota subgenus Lepiota with pleurocystidia is given , under the provisional binomial L. pleurocystidiophora.
