Ascomycetes from freshwater habitats: Ascolacicola aquatica gen et sp nov and a new species of Ascotaiwania from wood submerged in a reservoir in Hong Kong

Ascolacicola aquatica gen. et sp. nov., and Ascotaiwania mitriformis sp. no v., from decaying submerged wood collected in the Plover Cove Reservoir in Hong Kong are described and illustrated. Ascolacicola aquatica has characte ristics that are common to both Ascotaiwania and Savoryella, but the anamor ph is Trichocladium uniseptatum. A new genus is therefore introduced to acc ommodate this fungus. Ascotaiwania mitriformis sp. nov. is typical of the g enus and differs from other species in having large brown fusiform ascospor es with mitriform end cells. Its anamorph is an undescribed species of Mono tosporella and both states of the fungus are described and illustrated.
