Observation 55704: Elaphomyces Nees

Alexander H. Smith in “How to Know the Non-Gilled Fungi” said Elaphomyces is probably the most widespread and common truffle around the world. The gleba on this particular specimen was far advanced, as it is powdery and easily separating. Spores are easily removed by touching the sporocarp. Adrien has not had a chance to look at the spores yet, so was unwilling to speculate on what species it is. I too believe this is an Elaphomyces, and does not appear to have embedded spores within the peridium (outer shell).
