Hi again
I need your opinion on this Helotiale found on Veratrum album. I think it could be a Calycellina species.
Apothecia very densely gregarious, narrowly sessile, 0.3-0.7 mm in diam., whitish, amber when drying, margen even, only minutely downy as the excipulum.
They are growing on old stems of Veratrum album at 1700 m of altitude. Ascospores with low lipid content (< 10%). Asci 45-80 x 8-10, 8-spored, pore IKI bb of Calycina-type, arising from croziers. Paraphyses with slightly inflated tips with several not pigmented VBs, that stain in CRb. Ectal excipulum of hyaline textura globuloso-angularis. Margin with inconspicuous cylindrical with VBs, as the paraphyses.
Many thanks for help me
Zotto
Hi Zotto
The subiculum doesn't exist. Do you reject at all Calycellina as a possibility?
maybe IKI stains them red-brown?
Why doesn't a subiculum exist? Your photo reminded me of Pezizella parasitica.
On your nice section you have put the scale on it.
Yes, Zotto. The VBs exist, altough inconspicuous, without CRb. And they don't react in IKI.
There are not a well developped subiculum under the apothecia
Another one from your paradise we had not met yet .
The spore figure looks particular.
I would also doubt a Caycellina species, as Zotto does . Did you check whether the spore wall becomes violet in CRB ?
How about a Calycina ? These rather inconspicuous VBs coloured in CRB you can find for example in C. inopiculata (on Iris dead leaves)
Bravo pour cette trouvaille, anyway
Amitiés
Michel
Hi Michel
The ascospores don't become violet in CRb.
Calycina usually has VBs as well. Could you please repeat the species name, I did not well understand.
Zotto
the paraphyses I had in mind belong in Pyrenopeziza inapiculata , not Calycina
So forget my suggestion
Michel
