Inamyloid Peziza?
Viktorie Halasu, 18-08-2016 04:24
Viktorie HalasuGood morning,
I'd like to ask for your help with this small discomycete. At first I thought it either Leucoscypha semiimmersa or Peziza, but microscopically it differs from both:

Apothecia flat, about 5-6 mm diam, growing on sandy soil on a forest path, deciduous forest in lowland. There might be Scutellinia legaliae growing nearby. 
Ectal excipulum t. globulosa-angularis, medúlla of t. intricata. There might be a very thin layer of something like t. porrecta between them (didn't see it clearly).
Asci pleurorhynchous (like Peziza), IKI-, but some are coloring to orange-brown, 8-spored.
Spores smooth, ellipsoid, eguttulate, probably with one big nucleus, (17,3) 18-19 (19,6) × (10,2) 10,4-11,4 (11,9) um, Q = 1,6-1,8 (living spores shot into water mount). Spores have excentrical sheath, similar to some Pezizas. With IKI, something inside of about half the spores stains reddish (I saw this reaction somewhere but can't remember where).
I forgot to check paraphyses, will do that at sunday.

To me it resembles Peziza the most, but because of the lack of amyloidity I'm not even sure about genus.
Thank you very much.
