 The specific epithet pardinum is derived from the Latin pardus " leopard " , referring to its mottled or spotted cap . 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 .
