Edibility:

The smell of G. cooperi is faintly aromatic, and it is considered a good edible species that can be used much like morels.

Identification Notes:

Geopora cooperi is a fuzzy truffle that can become the size of a baseball. It typically is nearly spherical but often has an irregular to convoluted surface due to infolding of the peridium. The outer surface is brownish and covered with a mass of coarse flattened hairs. The gleba is whitish and pale brown and composed of multiple chambers. Similar to many cup-fungi and unlike most truffles, G. cooperi produces long cylindrical asci, each with eight smooth, broad elliptical spores that are forcibly ejected at maturity.

Accepted Name:
