Some Fungi in the Forest Soils of Newfoundland

Abstract

A study was made of the fungal population of acidic soils from six coniferous plantations in Newfoundland. Sixty fungi, belonging to 53 species and 25 genera, including 38 Fungi Imperfecti, 13 Phycomycetes, one Ascomycete, one Basidiomycete and seven sterile mycelia, were isolated. This is the first report of soil fungi from Newfoundland and includes several species hitherto not reported from boreal forests of Canada. The genera, in order of their frequency of isolation were Penicillium, Mor- tierella, Oidiodendron, Fusarium, Aspergillus, Mucor, Alternaria, Chryso- sporium, Cladosporium, Phialophora, Trichoderma, Rhizopus, Absidia, Aureobasidium, Cephalosporium, Colletotrichum, Cylindrocarpon, Crypto- coccus, Monilia, Myrothecium, Phoma, Verticillium, Cunninghamella, Chaetomium and Rhizoctonia. Soils from well drained to moist areas yielded a higher number of fungal species than those from dry areas.
