Observation 165956: Gymnopus earleae Murrill

When: 2014-05-25

Collection location: Hunlock Creek, Pennsylvania, USA [Click for map]

Who: Dave W (Dave W)

No specimen available

According to accounts I have read, the gills of G. earleae are yellow. But Halling says the one main difference between G. earleae and G. dryophilus is that the gills of G. earleae are darker. This appears to be the case with this patch of terrestrial Gymnopus, but the deviation from white gill color is slight with a few of the specimens. This is my reason for wondering about the earleae ID.

Terrestrial with stipe base encased within soil bound by rhizomorphs.

Rhizomorphs tawny, but a few small nearby specimens had whitish rhizomorphs. I did not include these in the photos, as they may represent a different species.

Cheilocystidia appear to be inflated, as opposed to filamentous. The micro photo is a mount of a gill. The hyphae seen in the other micro are the result of a “Roman aqueduct” section. I believe this represents the pileipellis.
