Podoscypha aculeata

Here is an apparently rare fungus known from southern Missouri, southern Indiana, South Carolina, and Brazil. It has turned up fairly regularly at the Missouri Mycological Society's annual Mingo Foray, and was often assumed to be a species of Cotylidia--until Missouri material was sent to mycologist Arthur Welden, who was able to provide an identification.

Thanks to Robert and Matthew Johnson for collecting, documenting, and preserving Podoscypha aculeata for study; their collection is deposited in The Herbarium of Michael Kuo.
