Abstract
Macrofungi from the alpine stage of the Pyrenees are poorly known. In this paper we first describe the alpine habitats of this mountain chain, then provide an overview with bibliography for all known taxa, with information on distribution and habitat. In addition to the 214 taxa of macrofungi previously known from the Pyrenees, 83 new taxa are reported from the French side of the Pyrenees. The total number of taxa reported for the alpine stage of the Pyrenees is now 297, of which 19 are Ascomycetideae, 260 Agaricomycetideae, 11 Gasteromycetideae and 7 Aphyllophoromycetideae. The genera richest in species are: Inocybe (53 taxa), Entoloma (41 taxa), Cortinarius (36 taxa), Hygrocybe ss. lato (20 taxa) and Melanoleuca (12 taxa). Of the 297 taxa reported, 103 are true arctic-alpine fungi.
