Popis: A new freshwater ascomycete isolated from submerged wood in New York is described as a new genus and species in the Phaeosphaeriaceae, Pleosporales. This species has globose, pseudopar- enchymatous ascomata, sparse, septate pseudopara- physes, fissitunicate asci and hyaline, cylindrical to fu- soid, phragmoseptate, isthmoid ascospores. The as- cospores are distinctive from those of other genera in the Phaeosphaeriaceae in having a central two- celled isthmus. In addition, the ascospores are sur- rounded by a gelatinous sheath that expands in wa- ter, a feature characteristic of many aquatic ascomy- cetes.
