Closeup of bisected specimens would help. Spores would help.

Well, it seems like they may be stalling and never developing as I observed these mushrooms again today and they are all even more blackened and cracked…still not convinced, oh well.

could be aborts

That happens sometimes. Sometimes mushrooms will start to form and them stall for a long time before fully developing. Sometimes they stall and never fully develop.

How long would it typically take for an urn to mature? It has been over a week and these specimens do not seem to be urning-out at all. I have seen the fully mature urns around the county for the past few weeks. Guess I’ll keep checking these ones, I appreciate the info, everyone.

Urnula for sure

These are immature specimens. I frequently find them growing from fallen sticks.

I have never found Urnula growing from logs. especially rotting ones. I Usually find them from small twigs and branches no bigger than 10 in in diameter. Second at the base of these it appears to be a common stem growing in clump like manner. usually Urnula will clump but the fruiting bodies are more separate. For a somewhat similar example of this observation See http://mushroomobserver.org/34896?q=mB.

Photographed these same specimens today and added a picture; still look fingery.

I’ll check

Wow, I hadn’t even considered that, I’ll check.

I suspect these are Urnula that have not yet opened. Are they still around a few days later to check? thanks.

I’m a little confused. Is this really an image of Urnula craterium? I thought they were deadmen’s fingers for sure. What am I missing?

Please send

Hi Anthony. Could you Please send me any Urnula that you find? We need as many as possible to extract a useful chemical. You can just air dry them and send to:

Tom Volk
Dept. Biology
1725 State St.
University of Wisconsin- La Crosse
La Crosse WI 54601

Thanks for your help!
