Observation 12171: Clavulina cinerea (Bull.) J. Schröt.
When: 2008-10-07
No herbarium specimen

Notes: This is a club or coral mushroom, fairly abundant, growing near but not on (mycorrhizal?) Lodgepole pine (Pinus contorta). I have never seen it before, and cannot key it out in Aurora’s Mushrooms Demystified. The top is creamy white to smoky buff, forked, lobed, branched, crenulate, and spiked. The base looks somewhat similar to a Helvella, but this is no Helvella I’ve ever seen before, and this is an unusual time of the year to see anything but Helvella lacunosa. Stipe is composed of multiple branches, possibly grown together, perhaps hollow; flesh-colored transluscent; fertile area is variously shaped like a stubby-branched coral or Helvella, sometimes with dull spike-like projections, sometimes crenulose like a brain. Odor not noticed. About 1.5-2 inches above the ground. Abundant fruiting bodies in a 2 square foot area.

Thumb through the list here on MO. Lots of them have a crenulate apex.

Just looked it up in M.D., and the written description could match. It doesn’t really loook like other C. rugosa I have found, but that doesn’t mean this isn’t a variant. Have you seen C. rugosa with a crenulose center, like this?
