Illustration for the term "fuscous".
From the New York Mycological Society Autumn 2011 newsletter, by Jason Cortlund, Editor, "fuscous" is defined as:
"From the Latin fuscus meaning dark, swarthy, or tawny. The adjective "Fuscous" (pronounced FUHS' kuhs) is a color description that refers to something of a brownish-grey hue or something that is dark or dusky. The bolete commonly referred to as Old Man of the Woods (Strobilomyces floccopus) certainly fits that description."
