Ocurrence of ectomycorrhizal, hypogeous fungi in plantations of exotic tree species in central Argentina

Abstract

Eleven hypogeous, ectomycorrhizal species of Basidiomycota, including two new species, and one of the Zygomycota were collected in exotic tree plantations in Córdoba Province, Argentina. Descomyces fusisporus sp. nov., D. varians sp. nov., Hydnangium archeri (Berk.) Rodway, H. carneum Wallr., Hysterangium gardneri E. Fisch. and Setchelliogaster tenuipes (Setch.) Pouzar were associated with Eucalyptus spp. Endogone lactiflua Berk., Hymenogaster lycoperdineus Vittad., H. griseus Vittad., H. rehsteineri Bucholtz, Rhizopogon couchii A.H. Sm. and R. roseolus (Corda) Th. Fr., were associated with various northern hemisphere tree species. Descriptions are provided to aid identification of the hypogeous fungi in exotic plantations of Argentina.
