Observation 64937: Cheilymenia Boud.
When: 2011-03-28
No herbarium specimen

Notes: Found by Dick Bishop in his backyard and brought to the OMS meeting.

Growing on bird seed; more specifically, nyjer (thistle) seed. Cups measure 1mm or less.

Mature spores from an ascus that had 7 of them measured 16-18 × 10-12 microns.
Paraphyses are cylindrical and (in most cases) thickened at end. I couldn’t observe septa in them. Hairs that I looked at had 2-7 septa.

Paraphyses changed color in Melzer’s. They look violet-brown to me, but I am not sure about this and would appreciate help in interpreting this color change.

I consulted Fungi of Switzerland, but couldn’t find a good match.

Dick measured the cups carefully: they are between 1 and 2 mm wide.

The hairs don’t seem to show anything fancy at the base. (Added one more pic.)

Cheilymenias did apear to be the closest match when I went through the Swiss book, but none of those shown really matched. The distinctive color change of paraphyses in Mezler’s is not mentioned with any of the Cheilymenias there.

Try Cheilymenia !

Try Cheilymania. Important characters are at the base of the hairs. Simple or branched, and how much branched if branched? Oluna
