How do you identify Torula?
Dematiaceous black-brown colonies forming chains of dark spores on decaying material Colonies are typically black, dark brown, olive with a velvety to powdery, dark texture. Musty, earthy odor Confirmation requires professional sampling and laboratory analysis rather than visual identification alone.
