The Illinois Mycological Association is a group of fungal enthusiasts that meets frequently to learn about fungi through talks presented by experts, and to look for, identify and document wild fungi. We host monthly meetings with invited speakers, mycologist-led surveys to gather and document fungi, and an annual show at the Chicago Botanic Garden.
We welcome you to attend and learn more about fungi and the wild mushrooms of Illinois and the Chicago region.
November Mushroom of the Month: Rhizomarasmius pyrrhocephalus / Hairy Long Stem Marasmius
Rhizomarasmius pyrrhocephalus, also known as the Hairy Long Stem Marasmius, is a tiny but tall mushroom that is usually one of the first agarics to pop up in the spring and one of the last to stop fruiting in the autumn months. Their size and duff color make them easy to overlook, but keen eyes can find them on woody debris. They tend to prefer hardwood and especially love hanging around oak trees in our areas.
