Observation 32003: Xeromphalina campanella group

When: 2010-01-14

Collection location: Prunedale, Monterey, California, USA [Click for map]

Who: Rachelle Lewis (Jasper)

No specimen available

These mushrooms are growing in clusters in and under the surface of wood chips on a school playground. They are an orangy-brown color. The gills are slightly paler. The slender stems darken to a reddish-brown as they get closer to the ground. The flesh of the cap is delicate with the stem being woodier. The cap is flat to concave with a dimple at the top. The cap is not domed or perfectly circular. The gills are visible on the surface of the cap, with slightly darker striation radiating from the dimple. There is no ring under the cap, and no cup around the stems. We had rain day before yesterday, and today there are thousands of these growing in the wood chips. Any help that you can provide in identifying them would be appreciated.

X. campanella indistinguishable from X. enigmatica without mating studies or DNA

Xeromphalina campanella can be distinguished from X. enigmatica only by mating studies or DNA sequencing. They’re effectively identical in macroscopic features, microscopic features, chemical features, geographic location, and substrate preference.
