Little brown Peziza
Zuzana Sochorová (Egertová), 21-06-2016 19:37
Zuzana Sochorová (Egertová)Hello,
this Peziza was collected in Slovakia, in altitude about 400 m asl., on soil in a ditch, 18 June 2016. Ascobolus viridis, Scutellinia legaliae and S. trechispora grew near it.
Apothecia 4.5-5 mm in diameter, sessile, brown, rounded or irregular, plane, warted on the outer surface.
Spores 19-21,5 x 9.5-10.8 micrometers, ellipsoid, hyaline, with a gelatinous sheat, without guttules, ornamented with warts of unequal size (up to 3 micrometers broad), sparsely distributed on the spore surface.
Asci 287-340 x 15-18 micrometers, amyloid, cylindrical, octosporic, uniseriate,
Paraphyses septate, containing vacuolar bodies, 3.2-4 micrometers, apex strongly broadened, 7-10 micrometers, rounded, sometimes slightly bent.
Excipulum of textura globosa, cells 14-34 micrometers broad.
It resembles eg. Peziza acroornata in some characters (macro, eguttulate spores with sheat), but the ornament seems different.
Thanks, Zuzana

Hola Zuzana.


Podría ser Peziza granularis. http://www.ascofrance.fr/search_forum/35625

Re : Little brown Peziza
Thank you Ruben, I also considered Peziza granularis, but it should have smooth spores... my fungus has ornament.

Re : Little brown Peziza
Dear Zuzka,

I'm not totally convinced that the warts can be seen as "real" ornamentation, because they are dispersed very unequally over the spores. I have seen warts on spores also on Helvella species, may be due to an overageing of the fruitbody. So it would not be too astonished about that being P. granularis, despite the spores being somehow warty.


best regards,
Andreas

Re : Little brown Peziza
Thank you, Andreas.
What is it, if not ornament?
If it would be some mess on the sheat, I shouldn´t be on the spores inside asci...

Re : Little brown Peziza

Dear Zuzka,


I didn't want to say that it is not an ornament, but that I have some doubts that the ornament is significant in this case.
Compare the foto of the ascus and spores of Helvella lacunosa - this species also has smooth spores and here the ornament is even more evenly dispersed on the spore than in your case.


I also don't want to say that the ornament is insignificant - only that one might have to take into account that it might be an artefact or an unusual "production", whatever reason this may have caused.


best regards,
Andreas

Re : Little brown Peziza
Dear Andreas,
thanks a lot.
Such a large genus, and it makes such treacheries in addition :-)
Unfortunately I found only two apothecia, one of which wasn´t mature enough to provide sporeprint, so I couldn´t test more fruitbodies.

Re : Little brown Peziza
What is the color of the vacuolar bodies in the paraphyses?

Re : Little brown Peziza
In my Cahiers FMBDS no. 4, under Peziza sublaricina (syn. P. dissingii), I illustrate a montainous species with similar ornaments on spores, but the paraphyses contain yellow vacuolar bodies.
This species was initially described by Heim & Rémy under the name Aleuria granulosa f. laricina, so considered as a form of Peziza granulosa Schumach.
I'm not convinced that Zuzana's collection could be P. granularis in the sense of Donadini, which has smooth ascospores (also a bit wider), and no vacuolar bodies in the paraphyses after my own collections.
But I have no name to propose!

Re : Little brown Peziza
Hello Nico,
your Cahiers is usually among the first books I check when trying to determine an operculate ascomycete. But I wasn´t able to imagine my fungus (which measured 4.5-5 mm and one of the fruitbodies was mature enough to give a sporeprint) could reach 20-35 mm as you give for sublaricina. The species looks also very different in the photo. Unfortunately I have no other own collections of (mature) little brown Pezizas for comparison.
