i don’t find this specie often, but it don’t really look like that for me, usually they are more of a fragile looking fungus , i really wonder if you can scope this one, it will be easy to confirm this way

Oligoporus ptychogaster is quite credible to my eye, but I also find Ptychogster albus out there and Postia ptychogaster. Which one is the current North American designation?

If this is the correct identification, my specimen is quite dried out, I would say.

I wish I could help you ID the large organism but I don’t have a clue. BTW there are various species of lichen growing on the wood’s surface but I don’t think the large specimen is a lichen. I thought at first it might be some sort of coral type mushroom but can’t find anything like it in the references I’ve checked. Hopefully someone can ID it for you as I am curious to know too!

No, this oddball was growing on dead wood (hardwood bark). It’s a really funny color for lichen.

The stuff out of focus in the foreground may be lichen and/or liverwort, and of course there’s lots of moss, but it’s the fuzzy tan blob I’m curious about.

Peter, it looks like these

are growing on rock, true? If so I have a general question for anyone willing to comment: other than the composite fungi, that is lichen spp., are there any that grow on rock?
