Strong KOH+ yellow reaction in Peziza
Perz Piotr,
19-09-2006 00:02
I have collected this species, and amyloid ascus apex tells me, this is Peziza (Peziza atrospora ??).
I does not have experience with this Peziza and three things are strange for me.
1. Hymenium is coverered by red/brown/purpur gel, KOH- and IKI-
2. On ectal excipulum are hyaline, thin-walled, smooth, 0-2 septate hairs, 50-100µm x 5-12µm, some with hyaline gelatinous exsudate.
3. Here is very strong, for a long time KOH+ reaction. When added KOH the whole excipulum, medulla und hymenium going strong yellow (like paraphyses in Mollisia rosae).
Is this KOH reaction normall for this (or also other) Peziza ? And this gel on hymenium? And the hairs ?
best wishes
Pimpek

Pourrait-on avoir des données microscopiques plus complètes (spores notamment) ? Avec si possible un dessin car personnellement je ne distingue rien sur ces photos qui aide à la détermination...

Re:Strong KOH+ yellow reaction in Peziza
Hi Jacques & Nicolas,
Currently I'm waiting for spore print. Spores are with grob-ornamentation, w/o apiculi, with 1 or 2 rops of oil. When I have some free spores then I will make a good drawnings.

Hi everybody,
My ?Pachyella (?Peziza) is fully fine mature and I have a lot o free, mature spores on glass :)

Re:Strong KOH+ yellow reaction in Peziza
Certainly seems to be a Pachyella. A section through the margin is your best bet in understanding the difference between Peziza and Pachyella. See the papers by Pfister. Several species have warted ascospores.

Re:Strong KOH+ yellow reaction in Peziza
cf. Pachyella adnata (Berk.& Curt.) Pfister . Verifier la présence de " hyphoïd hairs" sur l'excipulum ectal, beignant dans un gel.
