This is probably the same Phanerochaete picked up last year just above the valley, and it may be the same one that is common at Pt. Reyes that I originally confused with Piloderma. This particular specimen is the largest I’ve seen.
When I went to key it out in the Cortiaceae s.l. I was stopped at the first couplet because it says that Phanerochaete species do not stain with KOH (once the red-staining Rhizochaete are eliminated. But Karen Nakasone wrote back: “Did you consider Phanerochaete sanguinea? It has yellow cords that turn green in KOH.
Phanerochaete carnosa’s hymenium turns greenish black in KOH but it doesn’t develop cords.” And after pushing past the first couplet this specimen does key to P. sanguinea, but the solid green staining, really yellow-orange color vs. reddish, and the slightly smaller spores (5 X 2.5) make me think is something a little different from sanquinea. It also seems close to P. chrysosporium, but the color of that sounds paler, and the cystidia seem a bit larger.
