Micobiota de la ZEC Gándaras de Budiño (Pontevedra, N.O. Península Ibérica)

Abstract

The Special Area of Conservation (SAC) Gándaras de Budiño is located in the southwest of the province of Pontevedra (Galicia, Iberian Peninsula). In spite of the aggressions suffered throughout the history, still very representative zones of this one are conserved with fauna and flora own of these places and infrequent in the rest of NW Iberian Peninsula. It occupies an area of approximately 800 ha, which includes a large complex of wetlands (bogs, braves, alluvial forest and lagoons) as well as atlantics heaths, riverbank forest and more dry areas, consisting basically of mixed oak and pine forests. In this space, a mycological study is carried out with periodic collections for 4 years, resulting in a catalog with 359 taxa, with a contribution to the Galician catalog of 62 species. Among them is Chaetotyphula actinipes, which is mentioned for the first time in Europe, in addition to Arnium olerum, Byssosphaeria schiedermayeriana, Conocybe brachypodii, Cordyceps polyarthra, Hemimycena angustispora, Inocybe salicis, Laccaria impolita, Mollisia olivascens, Mycena atrovinosa, Mycena mucor, Oligoporus alni, Russula sphagnophila and Trichoderma piluliferum, not mentioned above for the Iberian Peninsula From the point of view of the trophic strategy the entomopathogenic species stand out: Beauveria bassiana, Cordyceps polyarthra, Gibellula pulchra, Isaria farinosa, and Torrubiella arachnophila. Of the remaining 125 are mycorrhizal, 211 are saprotrophic and 38 necrotrophic, in both cases, mostly lignicolous, justified because ¾ parts of the material has been collected in tree formations of Alnus glutinosa and Salix atrocinerea. In addition, we analyze the autoecology of the species, the fruiting patterns and the chorological contribution, both Iberian and worldwide.
