Recognized by sight: Psilocybe carbonaria does not fit because the caps are larger than 12 mm, and also due to the presence of an annulus. Looks like a Deconica, especially from above.

Recognized by sight: Alan if you look closely in the second photo there was slight bluing on the stems, and I added a pic of one with more obvious, yet still slight bluing effect. Doesnt this rule out Deconica?
