Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about Trichothecenes?
Summarize this article for a 10 year old
The trichothecenes are a large family of chemically related mycotoxins. They are produced by various species of Fusarium, Myrothecium, Trichoderma/Podostroma, Trichothecium, Cephalosporium, Verticimonosporium, and Stachybotrys. Chemically, trichothecenes are a class of sesquiterpenes.

The determining structural features causing the biological activity of trichothecenes are the 12,13-epoxy ring, the presence of hydroxyl or acetyl groups at appropriate positions on the trichothecene nucleus, and the structure and position of the side-chain. They are produced on many different grains such wheat, oats or maize by various Fusarium species including F. graminearum, F. sporotrichioides, F. poae and F. equiseti.
Some molds that produce trichothecene mycotoxins, for example Stachybotrys chartarum, can grow in damp indoor environments. It has been found that macrocyclic trichothecenes produced by S. chartarum can become airborne and thus contribute to health problem for building occupants.[1][2] A poisonous mushroom native to Japan and China, Podostroma cornu-damae, contains six trichothecenes, including satratoxin H, roridin E, and verrucarin.
