Notes: Single basidiome found in needle duff under Juniperus virginiana. Very small, cap diameter 0.6 cm.

small and broadly eliptical. I will upload pictures shortly. Also the base of the stipe is very distinctive, something I have only seen in Pseudobaeospora.

Thanks for the suggestion

I did not think this was Laccaria, but that’s an easy check. I’ll update with some microscopy.
