| Illustrated here is a single conidium of Microsporum canis. Note that the hilar cell appears fractured (short red arrow), where it was released from the stolon. Macroconidia having this so-called "break-away" cell are termed: | View Page |
| Match the names of each of the fungi listed with its appropriate category depending upon whether the multi-celled macroconidia are divided by both longitudinal and transverse septa (dictyospores); or, are divided by only transverse septa. | View Page |
| The multi-celled conidia of this dematiaceous mold are divided into cells by what are called distosepta (pseudosepta), indicating that the individual cells are surrounded by a sac-like wall that is distinct from the outer cell wall of the conidium. The identification of this mold is: | View Page |
| The oval or curved multi-celled, dark-staining macroconidia divided by transverse septa only is characteristic of: | View Page |
| The chain of conidia illustrated in this photomicrograph, with the deep-staining truncated bases, are called annelloconidia, and are most characteristic of: | View Page |
| Mucous Threads Mucous threads are semi-transparent under brightfield microscopy and could be mistaken for hyaline casts. They occur as ribbon-like strands with poorly defined edges, pointed or split ends and longitudinal striations. | View Page |
| Mucous Threads Under Phase Contrast Under phase contrast, mucous threads appear much darker. Longitudinal striations and pointed ends are easily visible. | View Page |
