Leptosphaeria includes some 500 species characterized by the papillate or conical ostiole, usually free from hairs. The majority are saprophytes on plant remains, some are parasites on land plants, and some on the Red Algae. L. Lemaneae occurs on the thalliis of various species oi Lemanea {?ig. 121). The mycelium consists of uninucleate cells and ramifies in the intercellular spaces of the host, sending branched haustoria into the cells. Here and there the hyphae are dilated (fig. 122 a, b), and in these regions sho

The height of projection of the ascospores occasionally attains a relatively enormous value if one considers that the perithecia are only about half a millimeter high in the middle. Thus in Podospora fimiseda, it reaches 15 cm. and in P. curvi- colla, as high as 45 cm. (Weimer, 1920). In other forms, as Leptosphaeria acuta (Hodgetts, 1917), Pleospora her- barum (Atanasoff, 1919) and P. scirpi- cola (Pringsheim, 1858), this disc

The Septoria tritici Desm. is closely related to the above and should per- haps be regarded as nothing more than a variable form oi S. gr
