Found on a well-rotting log. Looks similar to a Daldinia, but without the hemispherical shape. Nor does Daldinia come off its substrate so easily. And look what was underneath!

Very Hard

The fungus itself is very hard. But I think it came off the log easily because the log itself was well-rotted. Fungus was not at all hemispherical, nor parchment like. Rather, it was an irregular lumpy-surfaced, very hard conk-like form.

I don’t think this is U. deusta, which is a carbon crust and very tough to get off the log (a lot more so then Daldinia) Ustulina deusta is common in the northeast on old Sugar Maple stumps and logs, I’ll try to photograph some soon and post.
With the fuzzy white bottom it almost looks like a myxo.
