Hairy asco on Quercus ilex wood
Enrique Rubio,
02-04-2013 14:48
Hi to allHave you any idea about these substipitate, hairy ascomata up to 0.6-0.7 mm that grew on wood of Quercus ilex still attached branches?
The hymenium is brownish/violaceous and the hairs, multiseptate, minutely incrustate have a brownish base and subhyaline apex. They arise of the brownish, angularis to prismatica textura of the ectal excipulum.
Asi IKI negative, 8-spored, with croziers. Paraphyses filiform withouth conspicuous Vb's.
It has several affinitys with Zotto's collection HB 5363 E, as Lasiobelonium 'encoelia'.
Thanks again
All the photos of the hairs are made in KOH

Re : Hairy asco on Quercus ilex wood
Hi Enrique
it is a good idea to compare this with my Lasiobelonium, thoughthat has the hairs longer and more flexuous, and the granules on them disappear completely in KOH, unlike your fungus.
So I think yours fits quite well this Trichopeziza viridula that I also misnamed Hyphodiscus sericeus, for instance HB 9191 which has spores *(5.5-)6.5-9(-12) x 2.6-2.8 µm.
By the way, I find your spores 6-7.6 x 2-2.7 µm from the scale.
Is the excipulum section also in KOH?

Yes. The excipulum section is in KOH
What folder in your CD has Trichopeziza viridula or Hyphodiscus sericeus?

Re : Hairy asco on Quercus ilex wood
I assume can this fungus be also Trichopeziza viridula?

I think you will find it in Ascomycota\Helotiales\Lachnaceae\Hyphodiscus

Re : Hairy asco on Quercus ilex wood
Enrique, your previous collection is presently in my folder
Hyphodiscus aff., subfolder sericeus Europe, as
Trichopeziza viridula, 10.VI.2007-1.JPG
On the DVD (2005) this might be different, I don't know.
The name Peziza sericea was applied by Schweinitz for our fungus, but it is quite possible that Albertini meant with that name the very long-spored fungus now combined as Aerugineoscyphus sericeus by René.

Re : Hairy asco on Quercus ilex wood
OK., Zotto. In fact many young ascomata with greenish hymenium and white hairs are present this day on another branches. I think the material that I show is hypermature because their micro characters are the same.
Thanks Zotto and Chris!
