I’m finding three spp. which, macroscopically, (among what little photography I can find of each) look very much alike:

Coriolopsis sanguinaria
Antrodiella liebmannii
Rigidoporus microporus

All are reported from the tropics (though not necessarily neotropics). One of them may be your mushroom. I’ve yet to dig deep enough to see what may help separate the three. If upon any reading up on these any epiphanies emerge, I’ll post back here. It’d be nice to get to the bottom of the full two pages of iffily IDed Rigidoporus on the site, not just this one.

might have served as a valuable reference were it not for the vast majority of the shelf polypores being photographed dry.

Here’s a pretty extensive Costa Rican polypore checklist:


Perhaps Mr. Halling himself will weigh in on this find.

Not super thin, not very brittle, and I only found them in one spot.
Also, they seemed fresh. I am having trouble reconciling these with photos of R. microporus on the web, but I will look at my references tomorrow.

brittle, lignicolous and abundant? I take it these were the least hammered specimens you could find.
