# Characteristics of Colonies The image shows a table with characteristics of colonies, likely from a microbiology lab report or study. | Feature | Trichophyton tonsurans | Trichophyton violaceum | Trichophyton concentricum | Trichophyton verrucosum | |---|---|---|---|---| | **Growth Rate** | Moderate (14 days) | Slow (10 days) | Slow (10 days) | Slow (15-30 days) | | **Color** | White, downy, cottony, reddish-brown; visible pigment | Purple, cream, or light brownish color | White/cream | Grayish-brown | | **Surface Appearance** | Fuzzy/waxy; possible crater-like, greyish-white. | Globular surface |Globular, sometimes cerebriform. |Globular, sometimes verrucose | | **Reverse Color** | Grayish or brownish | Purple, cream, or light pink | White/cream | Light grayish-tan | | **Microscopical Features** | Septate hyphae are present. Possible presence of micro conidia, especially on the surface of culture. | Septate hyphae are present. Possible micro-conidia| Septate hyphae. Possible presence of conidia. | Septate hyphae. Possible presence of conidia. | | **Distinctive Features** | Possible variations in the morphology of hyphae and conidia. | May show a specific pattern or shape of conidia. | Possible variation in the conidia appearance. | Possible variation in the conidia structure appearance. | | **Other Characteristics** | Not reported | Not reported | Not reported | Not reported | **Notes:** * The table seems to be a record of observations for different types of *Trichophyton* fungi. * The terms "moderate," "slow," "rapid," "in frequent," and "infrequent" indicate rates of growth and development, while color descriptions, shape (e.g., crater-like, cerebriform, etc.) and microscopical features (e.g., septate hyphae) are used to provide detailed information. * Other information (e.g. "in vitro" tests on potato agar) concerning the behavior and characteristics of these organisms are noted. * There appears to be a column for "other characteristics" or "notes".
