Tiny orange cup-brown stellate bodies embedded in hymenium
Ethan Crenson, 28-08-2017 19:12
Hello,
I'm not sure what's going on here.  I found these tiny orange-tan cups (the largest about 2mm) on well rotted hardwood in Queens, New York City.  The hymenium of the more mature cups features black dots which, examined microscopically, appear to be brown stellate bodies embedded in the hymenium.  There are oblong tapered spores, some of which are 2-or more-septate.  The spores measure 13-32 by 2-3.5µm.  The arms of the stellate bodies are about 12-16µm long and about 4µm wide at the base. I was unable to see asci.  Are the stellate bodies native to the asco or from outside?  Any suggestion as to the genus and species?
Thanks,
Ethan

Hi Ethan

this reminds me of the following:

A Capronia was once found to grow abundantly on the hymenium of a Hyalorbilia (?H. inflatula) near Steuben, Maine (J. Karakehian & B. Liu pers. comm.), but the perithecia were apparently immature and thus remained unidentified.

Photos of this below.

I am not sure what spores you saw but you should try to find asci inside these perithecia.

Also in your case the host is Hyalorbilia inflatula or a closely related species.

Zotto,
Thank you so much.  I will try to work on the Copronia.  I recall seeing a single brown muriform dictyospore when I made my first slide, but since there was only one I thought it might be contamination.  Might that have been a Copronia spore?
