Observation 82365: Panaeolina castaneifolia (Murrill) Bon
When: 2011-10-08
Who: Byrain
No herbarium specimen

Notes: Growing in grass, near obs 79446. I checked every specimen in the second picture, they all had a few spores with oil drops, but were mostly without them. Smells of rotting fish in age.

Wow, the stacked spore picture does a great job of showing the ornamentation.

Hi. Just curious on what “Q” is and if you happened to ID the grass type?
