Aquatic fungi from peat swamp palms: Phruensis brunneispora gen. et sp. nov. and its hyphomycete anamorph
Phruensis brunneispora is a new genus and species occurring on decaying trunks of the palm Licuala longecalycata in Sirindhorn Peat Swamp Forest, Thailand. We compare the genus with other aquatic ascomycetes with falcate septate ascospores: Pseudohalonectria and Ophioceras. Ascospores differ from sp...
