. Fig. 99.—Cucurbitaria A, Stroma with pycnidia containing minute unicellular conidia. B, One of the large smooth pycnidia. (After v. Tubeuf.) The mature perithecia have a peridium consisting of a loose pseudoparenchyma with a rough warty exterior and a pore set in a distinct depression (Fig. 100.) The paraphyses are long, strong threads, often branched, and between them arise the long cylindrical asci with rounded ends. The normal number of ascospores is eight in each ascus, but fewer is no exception. In addition to the forms already described, pycnidia of still another sort occur (

They are spherical, with a dark-coloured coarse peridium, and are smaller than the stroma- pycnidia. These pycnidia contain no conidiophores, but give off
