Colletotrichum truncatum (Schwein. 1832) Andrus & W.D. Moore 1935

The fungus is wide-spread, especially in tropical and subtropical regions. It causes anthracnose on various crops like soybean, Capsicum or lentil. It also causes other diseases like brown blotch on cowpea.

Appressoria are light brown and irregular. The asexual fruiting bodies (acervuli) are surrounded by dark brown and thick walled setae. Conidia are sickle-shaped, aseptate and hyaline with a size of around 25 x 2.5 µm.
