Observation 31608: Hygrocybe russocoriacea (Berk. & Jos.K. Mill.) P.D. Orton & Watling

This was growing by itself under live oak ( Quercus agrifolia) really distinctive fragrance. Nearby was a large troop of Hygrocybe virginea which has no fragrance, and the last photo shows the two species side by side. I can’t distinguish them, which makes for a tough time identifying them if you are smell blind (My daughter’s phrase).

Spores at 1000x in Water
This last image shows H. russocoriacea on the left and H. virginea ( with no fragrance) on the right. I can’t tell them apart, except by fragrance and H. virginea often grows in large troops
