Peziza badia?

Please try to include photos to show all parts of the fungus, eg top, stem, and gills.
Note any smells, and associated trees or plants (eg oak, birch). A spore print can be very useful.

Peziza badia?

Post by Lancashire Lad » Mon Aug 24, 2015 3:16 pm

Found on Saturday. - Growing in stony soil adjacent to a surfaced woodland path. (Oak, Beech, Alder, Birch, & Holly, in the immediate vicinity).
Largest of fruitbodies shown approx. 25mm diameter. (Largest fruitbodies seen were approx. 30-35mm diameter).
Growing flat against the substrate with no stalk. (P.badia seen previously has been much more obviously cup shaped).
Flesh brittle - fruitbodies breaking easily into smaller fragments.
"Juice" from torn flesh of fruitbodies leaves a very weak yellowish stain on white tissue when dry.

Paraphyses septate, to about the same length as the asci, and with slightly clavate tips.
Asci 8 spored, J+ in Melzers.
Spores are about the right size for P.badia, but appeared to be more "echinulate" than "reticulate".

The spores don't seem to be quite what would be expected - but I can't find any other likely candidate.
Any thoughts or suggestions will be much appreciated.

Regards,
Mike.

Hello Mike,

surely not Peziza badia, shape and colour is wrong for it.
We should see the spore ornamentation to suggest other species. Therefore you need to make a preparation in cotton blue (several minutes of soaking, or better heating of the preparation without boiling) and have a look at 1000x magnification.

best regards,
Andreas

Hi Andreas,

Thanks for your reply.
I've done as you suggested, and photographed the spores in Lactophenol Cotton Blue at x1000 (Oil immersion).

The first shot is an attempted focus stack of 5 images - which I thought might give a better idea of the ornamentation, but my microscope camera does not give great results - so I'm not sure.

The second and third images are just single shots, focussed to try to show the ornamentation, so the major part of the spores are blurry.

I'm now convinced that the ornamentation is more reticulate than echinulate - but still not what would be expected for P.badia.

I still can't find any details for a Peziza that fits all the characteristics of this find.

With these additional spore images, do you have any further suggestions?

Regards,
Mike.

Hello,

I have no literature with me at the moment, but what about Peziza michelii?

best regards,
Andreas

Thanks Andreas.

P.mitchelii looks to be a good fit when it's in its more disc like form.
Certainly the spores look spot on for that species.

Best regards,
Mike.
