Caption:
Under a magnification of 400X, this photomicrograph revealed some of the ultrastructural morphology displayed by a species of the filamentous fungus of the genus, Gliocladium. Apparent here, were the thin-walled, transparent, or hyaline conidiophores, which were branched. At their distal tip you can see the flask-shaped phialides, and it's atop these phialides, taking the shape of an oval cluster, that the single-celled conidia emerge. This entire morphologic structure, i.e., conidiophores, phialides, and conidia, is referred to as a penicillus, from Latin for tuft of hair. Members of the genus Gliocladium morphologically resemble those of the genus Penicillium, however, as was the case here in this Gliocladium species, you’ll note that the conidia clump together in the shape of a single, ball-shaped mass, while Penicillium genus members display chains of conidia.
