El Programa biodiversitat micològica de les Terres de Ponent : notícia i primers resultats

Abstract

The Program on Mycological Biodiversity of western lowland Catalonia. Presentation and first results. Last autumn (1994) was exceptional in the area, in rain, air humidity and temperature. This enabled us to plan and to perform an intensive mycological survey (59 excursions, 64 localities prospected) of an area that is low and dry, rarely explored. The preliminar catalogue included here lacks a number of taxa as yet unidentified and has also been cleared of a set of trivial species, but the 170 taxa it includes should be useful to give a first idea about the xero-thermophilous mediterranean fungus flora in the area, mainly in the calcicolous bushlands (Rosmarino-Ericion), pine-groves of Pinus halepensis, and open and sunny soils. Some taxa are rarely reported: Eutryblidiella hysterina, Helvella villosa, Agaricus pilatianus, Amanita boudieri, Calyptella capula, Ceriporia bresadolae, Coprinus vosoustii, Henningsomyces puber, Hygrophorus carneogriseus, Marasmius corbariensis, Phellinus punctatus, Ramicola iberica, Skeletocutis percandida, Tulostoma nanum, T. occidentale, T. xerophilum, Typhula setipes, Xerocomus ichnusanus, and some others have been found outstandingly widespread and abundant: Mycocalicium minutellum, Amanita ovoidea, Clitocybe alexandri, C. umbilicata, Entoloma rusticoides, Hebeloma edurum, Inocybe roseipes, Lepista rickenii, Lopharia spadicea, Omphalotus olearius, Phaeotellus rickenii, Polyporus meridionalis, Suillus bellinii, S. collinitus, Volvariella speciosa, Mucilago crustacea. The Program is planned for some further years, in order to improve the survey.
