Found near Mirador el Roblar, El Sumidero

This collection represents a first country record of this species for Mexico, and only one of fewer than five records of the species away from the type locality in the Caribbean. The sequence is the first for this species (to our knowledge).

Small, clustered mushrooms found growing on the gnarled, seemingly burned stump ball of what appears to be one long dead and one living Madrona tree. Surrounding environment is on an island, high elevation forest of well spaced, mature conifers and thick, diverse moss blankets. Unique area. Mushroom is deep burgundy red, up to 3cm across the top. Very clean and uniform top. Stem is centrally attached, burgundy, and growing horizontally on nearly all mushrooms. Gills are closely spaced and deep burgundy as well, broadly attached/adnate. Never seen anything like this before. Last 3 photos show scraped spores from a print, put onto a dry microscope slide at 10/0.25 magnification. Spores appear ovate to slightly elliptic. @JRJFungarium

I wonder if this small plant could be Calyptridium monandrum (Common Pussypaws)? This one is about 3" across, and one of hundreds dotting the sand dunes. Many were much smaller. I vaguely remember it as a Claytonia.
