Observation 65300: Coriolopsis gallica (Fr.) Ryvarden
When: 2011-04-08
No herbarium specimen
0 Sequences

Notes:
On a dead cottonwood tree lying on the ground, barkless. Resupinate, growing underside, was barely visible before I flipped the tree.

Based on the look and staining of pores, this is almost certainly the same fungus as in observation 65116. Perhaps the pictures of the young fruiting bodies can help ID it with certainty?

Spores 12-14 × 4-5 microns.

Brown bruising

Datronia mollis bruises brown, or at lest appears to bruise brown due to a light bloom on the pores that is easily removed. It does look like D. mollis, but the spores are too large according to what I can find (8-11×2.5-4microns for D. mollis). The other observation definitely looks more like Coriolopsis gallica asides from the staining.

I think the place is called Willow Bar, or Willow Park. There is a road there, off Reeder Rd, to the parking at the beach. Driving up on Reeder, I usually park just where that road begins and walk towards the beach in the straight line. These polypores were found at the place where you cross the meadow and get to the trees near the beach. Good luck!

Give details of where in sauvie island? I have found coriolopsis gallica in portland and the surrounding area by the water is all hardwood. Im not too far from that area and can possibly check it out.

to this on account of this recent ob: http://mushroomobserver.org/65728

It won’t key out in the PNWKC polypore key (http://www.svims.ca/council/Polypo.htm) when taking into account the bright white pore surface of young specimens and near-immediate bruising where handled. All other aspects of C. gallica seem a match except for these two.

Here’s the much less hairy Hexagonia nitida (http://www.aranzadi-zientziak.org/...), some photos of which look promising minus the completely different cap surface. What’s more, IF indicates there’s been some crossover between Hexagonia and Coriolopsis over the years. Indeed, C. gallica was once H. gallica.

edit: I’m finding a recurring discrepancy between descriptions of the pore surface color and corresponding photos. Descriptions say grey to brown, photos occasionally show white. Even one of MycoBank’s accompanying photos on it’s own C. gallica page show a white pore surface:

The staining, however, remains a mystery.
