Observation 137635: Ascomycota Caval.-Sm.
When: 2013-06-25

Notes: These were growing on the roots of a fallen Oak tree. The specimens start out as translucent white jelly like substance breaking through the bark of the root. Then they turned redish-black and encusted as they dried, forming mounds with what looks like perithecia openings.

Could be a species of Nectria Debbie.

This has what looks like perithecia openings but I could be mistaken. I have looked and the asci do seem similar to Nectria haematococca. Example: http://www.bsu.edu/classes/ruch/msa/geiser/19.jpg and structure is also similar.

I have looked at an open specimen under the scope and the outer wall is thick purple-red and the interior is waxy, red-amber color which looked to have been liquid when fresh. The inner substructure is made up of layers of hexagonal webbing much like interior structure of a bee hive.

one of the Nectria sp.?

Certainly one of the ascos, at any rate.

Are you certain that there were perithecia?

I’m not so sure.

The specimens I collected were white and jelly like, then I watched as they darkened in color to a red-brown semi-translucent mass. Finally the next day they were almost black and looked rough and encrusted. I damaged other specimens when collecting this and there was no black structure under or in the jelly when I scraped them off.
John I would love to send you some specimens to analyze. I can’t find much information on fungi growing on Sequoia.

Things such as Tremella globispora, Tremella indecorata and 2 that may fit. If you have a collection I would be happy to work on it.

To me it looks like one of carbon looking ascos with a tremella growing on it. I will give you a few ideas.

scope it!
