B ShelbourneCudoniella tenuispora: Distinctive macro and habit
Spores 2-guttulate that seems verruculose but is not confirmed by the use of cotton blue.
Asci 8-spored, IKI negative (KOH pret. negative too), croziers +, up to 100 x 13.
Paraphyses polimorphic, without Vb's, embebed in a hyaline gelified matrix.
No crystals, no blue reaction in Melzer.
Margin of a firmly textura porrecta. Ectal excipulum of the flanks with a fine outer layer of cilyndrical gelified hyphae. All the layers are gelified too.
I think could be a Pezoloma species but I don't know what could be
Many thanks again
I had an energy supply problem here and therefore no computer access for two days.
Again a problem more! Obviously a Pezoloma, but no idea if I ever sa this.
Is the medulla similar as in the previous species, i.e. without apparent gel?

I only know the description in
DENNIS R.W.G. & HASSELL F.C. 1955 Some interesting Irsih fungi. Irish Natur. Journ. 11 ( 12 ) : 334-336.
Do you want a pdf ?

Zotto
My collection have a gelified medullary layer. In fact all the layers are gelified but specially the outer ectal excipulum.
Please can you send me Dennis's paper about P. obstricta?
Many thanks again
Enrique
Yes, 1955 has been a prolific year for Dennis !
Zotto have you a listing of its seven papers of 1955 ? I think they are all of the Kew Bulletin volume 10.
Perhaps you don't know
DENNIS R.W.G. 1955 Ascomycetes from Tristan da Cunha. Res. Norw. Sci. Exp. Tristan da Cunha 1937-38. 36 : 1-10.
Henrique, this evening, I shall send a pdf of the paper about Pezoloma obstricta. This publication is mentioned in
DENNIS R.W.G. & KORF R. P. 1958 A japanese species of Sphagnicola Velenovsky. Kew Bull. 13 ( 1 ) : 181-183.
Best, Guy
Pourras tu me mettre en copie des docs adressés à Zotto et Enrique ?
Est ce que la limite entre Pezoloma et Ombrophila est toujours claire, notamment avec, comme ici l'absence de vacuole réfringente homogène dans les paraphyses ?
Les autres caractères semblent proches ...
Amitiés
Michel
I actually miss an option of output in my database for references. Yes, most are of Kew Bulletin 10, but one is that for Tristan da Cunha.
Zotto
Dennis's description of Ombrophila obstricta (A Revision of the British Helotiaceae...) is confuse. He says pore slightly flushed with blue on the outer surface in Melzer's reagent. And he drew ascospores as conspicually fusiform with acute ends whereas the ascospores of my collection have obtuse ends.
Bonne lecture
Amitiés, Guy
And thanks to Guy for the scan.

To avoid misunderstandings: the attached photo is part of the medulla? But you said the medulla is gelatinized? This looks like a thin-walled t. prismatica without gel.
Zotto?
