Peziza aff exogelatinosa
Viktorie Halasu, 13-07-2018 17:59
Viktorie HalasuHello forum,

we found this small Peziza (5-12 mm diam.) on forest road (mix of clay and sand). I'd call it P. exogelatinosa, but this one has simple septate ascus base (exogel. was described with pleurorhynchous). What do you think?  Soc. Cupulina ascophanoides, Pachyella pseudosuccosa, Scutellinia kerguelensis etc.

Thecium violet when young (like Marcelleina), later (violet-)brown, outside glabrous and cca whitish. 
Spores * (15,9) 16,6-18,4 (19,2) × (9) 9,6-10,3 (10,7) ?, mean = 17,4 × 9,9 ?, Q = 1,67-1,87 (freshly ejected in water), with very fine and dense punctuate ornamentation. Narrow gelatinous sheath present, uninucleate. Some were germinating (from one or both poles, usually only single hypha). 
Ectal excipulum t. globulosa mixed with thin brownish hyphae, surface covered with gel. Medulla loose t. intricata sometimes with bigger cells. Asci IKI+ (apex strongly blue, the rest lightly), aporhynchous base. 

Thank you in advance for your opinions.
Viktorie

Re : Peziza aff exogelatinosa
Interesting collection. Species with aporynchous asci are uncommon in Peziza s.l.
I confirm that P. exogelatinosa has asci with crozier, and the spore ornamentation is a bit different, less visible. Usually the apothecia are also more cupulate.
You collection reminds P. pauli but the latter has shorter ascospores.

Your fungus is probably something new... in the hell of violet species!

Re : Peziza aff exogelatinosa
Hello Nicolas, 
thank you, I was not sure about croziers in exogelatinosa. Would you please have some image of the ornamentation from standard LM so that I would know what it looks like?
There was another violet-colored Peziza last year that I thought might be exogelatinosa, but it has even bigger ornamentation, too big spores for retrocurvata + -oides, and external gel layer as bonus. I'll put together some photos and post it.
