Abstract
The submergence and systematic examination of basswood and yellow pine panels at the far northern marine sites at Kodiak, Alaska; Nanaimo, British Columbia; St. Andrews, New Brunswick; Halifax, Nova Scotia; Liverpool, Nova Scotia; and Argentia, Newfoundland, during periods of water temperature of 0 °C to 15 °C, has demonstrated the abundance of an active ascomycetous and deuteromycetous mycota. The dominant fungal biota includes Lulworthia, Ceriosporopsis, Peritrichospora, and Halosphaeriopsis, and the Imperfect genera Piricauda, Humicola, and representatives of Helicosporae. Incubation of these infested wood panels has indicated fungal attack upon the panels in addition to that found at the initial examination, and has facilitated a more complete evaluation of the total lignicolous mycota, as well as establishing the early infestation of the wood. Differences in the dominant mycota between northern and southern environments are apparent, especially among the Deuteromycetes. Various genera and species extremely prevalent in warmer oceanic areas have not been found in colder marine environments.
