Lignicolous and zoosporic fungi in marine environments of Hudson Bay

Abstract

Wood and soil samples from Churchill and Great Whale (Hudson Bay) were surveyed or baited for recovery of marine fungi. A total of 14 ascomycetes, 7 fungi imperfecti, and 13 zoosporic fungi are reported. Amylocarpus encephaloides, Cephalosporium sp., Corollospora comata, Dictysporium pelagicum, Haligena amicta, Haligena elaterophora, Halosphaeria maritima, H. mediosetigera, H. quadriremis, H. stellata, Herpotrichiella ciliomaris, Nais inornata, Papulospora halima, Phialophora sp., Phoma sp., Schizochytrium aggregatum, Thraustochytrium aggregatum, T. multirudimentale, T. pachydermum, T. roseum, Trichocladium achrasporum, and Zalerion varium are recorded for the first time from arctic marine sites. Each species is discussed in terms of morphological features, taxonomic deposition, and ecological considerations.
