Much of the snow from earlier in the month is gone now, so I decided to look for some small things to do some macro photography. I found a little black cup fungi, and a small bryophyte. All of these photos were taken with the Canon 65mm 1-5x macro lens and available light.
I think this is Aulacomnium androgynum, mostly due to gemmae structures I saw that are not visible in this photo.
Black Reflecting Cup (Plectania sp?) growing on rotting wood. I've observed here in past years also.
Black Reflecting Cup (Plectania sp?). The flesh of this fungi is quite firm, though it's not difficult to rip it.
Black Reflecting Cup (Plectania sp?). Although the inside looks like it might be slimy, it hasn't been when I've touched it.
I think this is Aulacomnium androgynum based on the gemmae structure, size and habitat.

Nice job, Matt– I love your close-ups. And I’m impressed, as ever, with your ID skills– I’ve never tried to tackle leafy liverworts; haven’t a clue! Could the fungus be Sarcosoma? “Black rubber cup” in my Audubon guide, though I like your name better.
Thanks, I’m glad you enjoyed them. I enjoy getting photos of little things from time to time. I don’t think this fungus is a Sarcosoma, but I wouldn’t bet the bank on it. It’s been suggested to me before that Plectania is probably the correct genus, though I’ve not yet managed to find an appropriate species.
