👉 Xylosteini are a group of fungi that primarily produce xylose, a sugar found in plants and some types of bacteria. They are characterized by their spore-bearing form, with each spore containing a large number of xylanoglycan units (xyloids). Xylosteini also have the ability to synthesize carbohydrates from organic compounds through a process called xylanase, which is essential for their survival and growth.
