Typical lists of mushroom forms (agaric bolete polypore crust…) are familiar and useful but we don’t often give the forms themselves much attention. This presentation will be a casual attempt to add some precision and thoroughness to how we think about the forms relating them to each other and giving extra attention to the in-betweens – mostly with pictures. Jacob Kalichman has been practicing identifying gilled mushrooms by sight since 2010 especially in California and Tennessee focusing on little-known and difficult-to-distinguish genera. He is fascinated by the evolutionary relationships among mushrooms and keeps track of the genus-level taxonomy of the gilled ones and their relatives at www.agaric.us. He wrote the species text for the forthcoming Audubon guide and is currently a field mycologist collecting for the Matheny Lab at the University of Tennessee with an extra focus on Inocybaceae (fibercaps).
