Investigation of the funga of Surtsey 2008

Abstract

In August 2008 eighteen specimens of at least ten species of agarics (mushrooms) were collected on Surtsey. Entoloma sericeum was well established in grassland in the oldest part of the gull colony and at least seven ectomycorrhizal species, Hebeloma collariatum, H. marginatulum, H. mesophaeum, H. vaccinum var. vaccinum, Inocybe lacera var. lacera, Laccaria laccata and an unidentified Cortinarius species, were collected near their Salix hosts. one Psilocybe species, P. inquilinus, and one unidentified Entoloma species grew in Leymus dunes. Three collections identified to the genus Entoloma and three to the genus Hebeloma could represent two additional species. The findings in 2008 increase the total number of agarics from two to nine and of species of fungi on Surtsey from 26 to 33, counting only those which have been identified to species.
