Bonsoir à tous,
ca ressemble un peu à Perrotia coccinea fiche HB 6433 du disque de Baral (Helotiales-Lachnaceae-Perrotia ) mais ça ne pousse pas forcement sur Salix (donné sur Lonicera sauf erreur )
Bon courage;
Robert

Hi Robert,

My species. even dry or rehydrated is yellow and does not have IKI or KOH+IKI reaction. Also I have no intercellular reddish gel, only gelatinous exsudate on hairs and ectal excipulum, and every ascus is with true croziers.

I know - the colors can be not important, OK. Then, if the KOH+IKI reaction can be not constant - then the species can be identyfied als HB6433.

Now is importatnt to gen another description and see, what are writing other mycologis.

I have great dificulty in assuming this to be a Perrotia. I must congratulate you on the beautiful microphotos in your download! I'm sure Zoitto willl be interested in the hymenial parasite. The spore septation and great shots of the croziers are well-documented.I really have no good idea of a better generic position, I'm sorry to say.

Hi,

I have next found of this species

close up

Spores are mostly 1-septate (also 2-celled) in turg. asci, but sometimes up to 3-septate (also 4-celled)

This is the found from bark of Salix. Any idea? Any help?

best wishes from Poland

Hi Piotr

like in your "Pezicula", I here guess that the species is undescribed and its resemblance with Perrotia, in my opinion, restricted to the shape of asci and spores. In the other features the species resembles genera like Cistella or Ciliolarina, perhaps Pseudohelotium.

Such inamyloid hemispherical ascus apices as in your fungus are surely an adaption to a xeric environment, and derive from the loss of a conical amyloid apex during evolution. Spores of such a n allantoid shape occur in various groups, actually.

I searched for a name for this fungus since I heared of it from your previous find last year, but so far I found nothing. If Velenovsky would have worked more carefully we would perhaps have a chance to find it among his drawings.

Hallo!

Thanks Zotto. Also unknow genus, something like 'Cistelloperrotia' :) I try to find someone in Poland to obtain anamorph - may be this can help us to find the correct genus ?

best wishes
Pimpek

An anamorph and a sequence would probably help. But a new genus is not surely necessary for inamyloid asci with hemispherical apex. Look in Lachnellula, such occur there also.
Zotto

Hi,

by writing "correct genus" I think not "new genus", but "propertly genus". I means the genus of course can be an existing genus, but with anamorph is much easy to find them !
