Observation 97796: Panaeolus papilionaceus group
When: 2010-12-30
No herbarium specimen

Notes: These mushrooms were found growing on cow dung. The photos show the black spore print, and some dimensions. Ryane Snow thought it could be P. subbalteatus. No material was saved, but I do have the spore print,and notes. Most dimensions can be seen in photos. Stem 4 mm in diameter and 7cm long, tough, fiberous. No staining, though collected in very wet conditions which may have affected that.

Thanks for the clarification on the name Danny. This mushroom didn’t key out well—I’m limited to macroscopic observation. The cap does have interesting texture. P. retirugis in MDM is described as having a netted/reticulate cap.

that is a rather righteous cap surface you have here. Never seen one in Panaeolus so awesomely patterned as this. Reminds me of Rhodotus palmatus:
