They vary in size, and can generally be distinguished bythe central vacuole. The threads are the mycelia, which are, as a rule,coarsely granular and segmented, and contain a number of spores. They.

Besides the oidium lactis, both the penicillium glaucum and differentvarieties of aspergilli may be found in the urine, the former being quitecommon (see Fig. 75). The diagnosis of penicillium or aspergillus can be*made only by the characteristic fruit-bearer or sporangium arising fromnthe hypha. In penicillium glaucum, the most common mould fungus, theehyphse divide and subdivide into thread-like formations—the basidia andsterigmata—the ends of which latter are surmounted by a number ofspores or conidia. In the aspergilli no division takes place, but the hyphaterminates in a spherical or club-shaped vesicle, from the periphery olwhich a number of short fiask-iike formations—the sterigmata—are vis
