I do not have that reference (yet!).

Do you by any chance know what the black “earthstar” in observation 106376 might be? It was fruiting on a road cut pretty near where I found the S. polyrhizum.

I cut one of the black ones open.

into irregular-shaped rays definitive for S. polyrhizum. See Smith, Smith & Weber “How to Know the Non-Gilled Mushrooms”, p. 251.
