Nine ascomycetes, 1 basidiomycete and 15 mitosporic fungi are reported from submerged wood, collected from a single English river site. Ascotaiwania pallida, Neta angliae and Trichocladium englandense spp. nov. and Frigidispora colnensis gen. & sp. nov. are described and illustrated. Most of the species present on the submerged wood appear to have been identified, for the single date and location sampled, because the asymptote of the accumulative curve was reached between 80–100 substrata. The results of this study are compared with those from collections, using similar collection techniques in tropical regions. Results suggest that temperate streams appear to have a lower fungal diversity than in the tropics. Only Acrogenospora sphaerocephala was common to tropical (Seychelles) and temperate (U.K., River Coln) sites.
