Brunneosporella aquatica gen. et sp nov., Aqualignicola hyalina gen. et spnov., Jobellisia viridifusca sp nov and Porosphaerellopsis bipolaris sp nov (ascomycetes) from submerged wood in freshwater habitats

Brunneosporella aquatica gen. et sp. nov., Aqualignicola hyalina gen, et sp . nov., Jobellisia viridifusca sp. nov, and Porosphaerellopsis bipolaris sp . nov. are described and illustrated from wood submerged in freshwater coll ected in Hong Kong. Both Brunneosporella and Aqualignicola have characteris tic features of the Annulatascaceae and their placement within this family is discussed. Jobellisia viridifusca sp. nov. differs from all described sp ecies in having an ascomatal wall with a bright orange middle wall layer an d fusiform, greenish-brown ascospores. Porosphaerellopsis bipolaris sp. nov . is unique in producing multiseptate ascospores with bipolar mucilagilous pads.
