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

Abstract

Ascolacicola aquatica gen. et sp. nov., and Ascotaiwania mitriformis sp. nov., from decaying submerged wood collected in the Plover Cove Reservoir in Hong Kong are described and illustrated. Ascolacicola aquatica has characteristics that are common to both Ascotaiwania and Savoryella, but the anamorph is Trichocladium uniseptatum. A new genus is therefore introduced to accommodate this fungus. Ascotaiwania mitriformis sp. nov. is typical of the genus and differs from other species in having large brown fusiform ascospores with mitriform end cells. Its anamorph is an undescribed species of Monotosporella and both states of the fungus are described and illustrated.
