Observation 14526: Hypomyces cervinigenus Rogerson & Simms

When: 2008-11-23

Collection location: Larch Mountain, Multnomah Co., Oregon, USA [Click for map]

Who: Daniel B. Wheeler (Tuberale)

No specimen available

This is either a Hypomyces (rare on Helvella lacunosa in my experience in this area) or Clitocybe sclerotoidea on Helvella lacunosa (common in my area, but seldom parasizing such a large specimen of Helvella).

Used references: Arora’s Mushrooms Demystified. This must be a Hypomyces instead of Clitocybe, because it is growing on a mature Helvella. Clitocybe sclerotoidea colonizes the Helvella while it is still underground, and the mycelium attaches itself to much of the duff at the base of the Helvella, creating a structure similar to a truffle, but often covered by needle duff. Arora notes that on mature Helvella lacunosa “is frequently disfigured by a white, moldy-looking parasite (Hypomyces cervinigenus).”
