Mushroom Description Pages

Building pages for the 1200 different kinds of macro-fungi in the Chicago area. These are examples of the first species pages. There are also higher level pages from Kingdom down to genus. For example: Cantharellus, Hypocrea, Stereum, and Trametes. For all of the fungi pages see the Guide Site Map.


There are 21 Orders for the Class Agaricomycetes (the mushroom forming fungi). Half of these groups were described after the start of DNA analysis, many of them within the last ten years, as multigene methods improved. Check out who's who in these pages below.

Highlights from other websites

Mycologists from USA and Canada are proposing fungi for the Global Fungal Red List. See the mushrooms from the April Workshop.
