Biflagellospora (aero-aquatic hyphomycetes) from submerged wood in Thailand

Four species of Biflagellospora are reported from submerged wood samples in Thailand. They are characterized by simple, cylindrical, mostly geniculate, brown conidiophores with one or more sub-hyaline to light-brown conidia bearing long filiform appendages on each of two terminal cells. B. japonica is a new record for Thailand. B. siamensis, B. papillata and B. gracilis are described as new species.
