 The generic name derives from the Greek "trichos"/τριχος "hair" and "loma"/λωμα "hem", "fringe", or "border".Common names include striped tricholoma, spotted tricholoma, tiger tricholoma, poison trich, leopard knight, and tigertop.Dirty trich was a name coined by author Gary H. Lincoff in response to a publisher's request for a more accessible name than its binomial one for North American guidebooks.
