Genus/species: Trichothecium roseum
- Cell: ellipsoidal, filamentous; young conidia are aseptate
- Colony: Malt agar: Flat, pink colonies
- Spore: conidiospores ellipsoidal to pyriform, 15-20 x 7.5-10 micrometers, constricted at or near the septum (Watanabe). Septum develops when young conidia mature. Initially they are aseptate.
- Liquid Growth:
Produces in vitro as well as in vivo the toxic metabolites trichothecin, trichothecolone and rosenonolactone (Schwenk).
Found in soil, decaying plant material and also found on grapevine berries particularly with high humidity or following rain; normally associated with Botrytis infection.
Role in wine:
Grapevine disease agent, cause of pink rot
Can cause a bitter taste in wines made from infected berries
