Study Notes
Fungi Characteristics
- Dematiaceous fungi produce pigment best at room temperature.
- The main sterol in the cell membranes of dematiaceous fungi is ergosterol.
- Dematiaceous fungi are the causative agents of phaeohyphomycosis, chromoblastomycosis, and eumycotic mycetoma.
- Molds grow from structures called hyphae.
- An example of a dematiaceous fungus is Curvularia lunata.
- A characteristic of dematiaceous fungi is the production of dark-colored pigments.
- Dimorphic fungi can grow as either molds or yeasts.
- The main component of the cell wall of eukaryotic fungi is chitin.
- The characteristic feature of hyphae in dematiaceous fungi is the presence of melanin, which gives them a dark color.
