Abstract

The new genus Polythrinciopsis, with the type species P. phragmitis, is described from a leaf spot of Phragmites communis Trin, in eastern New South Wales. The genus is characterized by hypophyllous conidiophores, which develop in clusters from a few fungal cells in the stomatal opening and which show a strongly unilateral placement of spore scars; by large, hyaline to very pale olivaceous, two-celled, acrogenous conidia; and by an abundant superficial mycelium developing on the under side of the leaf spots. The relationship of this fungus to some other genera of the Fungi Imperfecti is discussed.
