Jelly Fungi

[ Basidiomycetes . . . ]

by Michael Kuo

The jelly fungi comprise a diverse and complicated group within the Basidiomycota. Identification of species often hinges on microscopic examination, and things are further complicated by the fact that it is often difficult to transport a jelly fungus home in "examinable" condition, to say nothing of the difficulties encountered with trying to dry and preserve specimens.

For now, anyway, I provide only a cursory treatment of the jelly fungi; the pages linked below represent some commonly encountered species. A list of references is provided below for those who want to pursue jelly fungus identification further.
