Mushrooms have all kinds of cool names for their various parts - pileus (cap), stipe (stem), annulus (ring), volva (cup at base) and others. But the best is the umbo. It doesn’t really give you a clue as to what it is. Unlike the ones above, it doesn’t have a more common name. It’s an umbo. It’s the little protuberance some mushrooms have sticking up from the center of their cap. Many are rounded and some are pointy like on these Rufous Milkcaps. Ummmmmbo. 🤭 #FungiFriday #Fungi #Mushrooms
