Observation 202100: Pezizales J. Schröt.
When: 2015-03-24
No herbarium specimen

Notes: In presumably finished compost laid in my garden about a month. Macroscopically Pyronema seems a possibility, but it seems doubtful that anything burned would be in my household compost. There were wood chips from a tree trimming company, so I guess I can’t rule out that some of them might have somehow been scorched. 1-2 cats occasionally use the garden as a litterbox, so I can’t rule out scat remnants either, although none were obvious. Spore length 12.5-22.5 microns, width 10-17.5 microns.

That is a bit large for Pyronema omphalodes & domesticum (10-15 × 5-8.5) according to Ascomycete Fungi of North America p. 240. The same page mentions Iodophanus carneus with spores 17-22 × 10-12.

I think

Iodophanus is a good lead, only other thing I can think of that is even remotely similar is Nectria peziza/Nectria terrestris (but they don’t actually look much like this)

Mounted in blue stain?

It was either mounted in water or a blue stain (but definitely not Melzer’s). At the time I scoped this, those were the only 2 mounting liquids I had.

what was this mounted in?

Iodophanus is so named for having acsi that turn blue all over in Melzer’s, and as such, are highly distinct among discomycetes.

this should be uploaded to AscoFrance
