Genuina

Tricholoma is a genus of fungus that contains a large number of fairly fleshy white-spored gilled mushrooms which are found worldwide generally growing in woodlands. These are ectomycorrhizal fungi, existing in a symbiotic relationship with various species of coniferous or broad-leaved trees. The generic name derives from the Greek trichos (τριχος) meaning hair and loma (λωμα) meaning fringe or border, although only a few species (such as T. vaccinum) have shaggy caps which fit this description.
