Abstract
Blogiascospora n. gen. is described for B. marginata (Fuckel) n. comb. (≡ Massaria marginata Fuckel) because study of the type revealed that the asci are unitunicate with a pulvillus and amyloid annulus, and that the ascospore walls are pitted. Study of Fuckel's specimens tended to confirm his conclusion that Seiridium marginatum Nees ex Steudel is the conidial state. Von Höhnel's confirmation of this connection was not borne out by a re-examination of his specimens. S. marginatum is redescribed and illustrated from a neotype. These characters are emphasized: the hydrophilic outer layer of the conidiophore, the echinulations arranged in longitudinal ridges on the four central cells of the conidia, and the sequence of septum formation beginning near both ends of the conidia. The taxonomy and nomenclature of S. marginatum and Seiridium Nees ex Fr. are discussed.
