Trichothecium

Trichothecium is a genus of fungi belonging to the order Hypocreales. Members of this genus are characterized by their conidiophores, which are typically branched, and their conidia, which are often hyaline and two-celled, borne in chains. The conidia are generally ellipsoidal or obovoid in shape. Trichothecium species are commonly found in soil, on decaying plant material, and as endophytes in various plants.

The most well-known species, Trichothecium roseum, is widely distributed and often encountered as a saprotroph. It can sometimes be observed as a secondary invader on fruits and vegetables, causing rot. While generally considered a saprophyte, some species of Trichothecium have been investigated for their potential to produce mycotoxins, although they are not as extensively studied or as agriculturally significant in this regard as some other fungal genera. Research on Trichothecium has also explored its interactions with plants, including its role in decomposition and potential antagonistic properties against certain plant pathogens. The taxonomy of Trichothecium is subject to ongoing research, with molecular data contributing to a better understanding of its phylogenetic relationships within the Sordariomycetes.
