- Hyphae: Narrow, septated, branched. Characteristic branching mode with short, thorn-like primary branches that are acute, obtuse or at right angles to the parent hyphe. Lateral branches usually grow in opposite directions (cross-over hyphae). Wreath-like arrangement of the hyphae bundles.
- No macroconidia.
- Microconidia: Frequent, acladium-shaped, solitary or grouped, 1-2 chambers.
- Chlamydospores often arranged in chains.
- Frequently disintegration of the mycelium into arthrospores (fragments visible).
