of globose spores and sandy habitat is fairly unique … a quick peek under a scope would nail it, if you can refind those fruit bodies.

It does look good for S. brunnea … but w/out the micro you just won’t know for sure.

In your opinion, what is most important to look for?

Ascomycetes of NA highlights globose, smooth, hyaline, w/ 1 large oil drop…anything else? Thanks for keeping me honest;)

well, it COULD be brunnea …

Debbie, I am adding additional photos. I’ve been using image processing software to play around with photos and in this case I changed the color a bit more than I wanted to. See the two new photos. Also, I do not have specimens in hand so I am unable to confirm microscopically.

can you confirm …

with the microscopy? It looks a bit too orange for brunnea.
