It was so dark in that forest, about a half hour before dusk, and we were trying to keep moving. I didn’t have the time to set up a tripod, but I suppose I could have tried using a flash.

The description of H. lacunosa by the Pacific Northwest Key Council states: “upper surface pale gray to blackish, […] some specimens are a pale creamy white, due to lack of pigment; some may be white due to being overgrown by a parasitic mycelium…”

This was the only patch of Helvella of any species we saw that day. Based on their close proximity to each other and similar morphology, and given the description above, I figure they are all color variations of H. lacunosa arising from a common mycelium.

Two species..

Some appear to be being attacked by Hypomyces cervinigenus.
