Observation 301154: Xylaria Hill ex Schrank

Original ID: Xylaria polymorpha (Pers.) Grev.
Growing on red alder (Alnus rubra) debris and dead stump in a Sitka spruce (Picea sitchensis) stand on the margin of a tidal slough.
Local naturalists (e.g., Johnson Clint Kendrick) showed this to mycologists working on The Outer Spores, Mushrooms of Haida Gwaii (Oluna Ceska & Paul Kroeger)
Not collected!
Fruiting bodies ca. 25+ cm long and 2-3 cm wide

It DOES look like X. polymorpha, though the photos are a bit bleary. I wouldn’t rule out Xylaria ‘atropctor’ based on that photo (particularly given that it’s on alder, the preferred substrate of X. atropictor). If no one examined the spores closely, and no anamorphic state was seen, I’d probably leave it identified only to the genus level, personally.

Phaeolus or Xylaria. seems like an extremely easy distinction to make.

I’m afraid the Masset weird and quite large finger growths turned out to probably be an abnormal growth of Phaeolus schweinitzii. I saved a piece, my number PK5401, which I examined microscopically and found had a hyphal structure consistant with old Phaeolus. I passed the sample on to Jim Ginns. Under dissecting scope the surface had irregularly shaped pores. In searching out images of Phaeolus on the web I found a few examples of abherrant antler-like growth forms similar to what we saw on Grahan Island.
