Pyreno on Corylus (Alnus?) bark
Enrique Rubio, 23-06-2009 19:21
Enrique RubioHi to all:
I wish to know your opinion about this fungus that grew on Corylus (Alnus?) bark.
Ostiolate tubular necks erumpent across an stromatic and withish-ochrceous disc of 1 mm.

Apical apparatus of the asci seems to be slightly reddish in IKI

Crytodiaporthe? Melanconis?
Many thanks again

Re:Pyreno on Corylus (Alnus?) bark
maybe Melanconis alni Tul. & C. Tul.

Re:Pyreno on Corylus (Alnus?) bark
Oui, Enrique y a pensé, on reconnait Alnus au vu de la photo mais a-t-on déja vu de pareils appareils apicaux sur cette espèce ? La réponse à cette question m'intéresse aussi fortement.
Bonne soirée,
Alain

Re:Pyreno on Corylus (Alnus?) bark
Dear Christian:
Can be so long the M. alni appendages? Have you any notice about the reddish IKI reaction of the asci apical apparatus?
Enrique

Re:Pyreno on Corylus (Alnus?) bark
Bonsoir Christian et Alain:
Munk's description of Melanconis alni says: ' no distinct apical structure seen'

Re:Pyreno on Corylus (Alnus?) bark
Enrique, please test IKI also after KOH for a possible blue reaction, and MLZ without KOH. Would be very interesting to see whether the apical rings are dextrinoid or hemiamyloid.

Re:Pyreno on Corylus (Alnus?) bark
Yes. I will do it

Re:Pyreno on Corylus (Alnus?) bark
Hi Enrique

did you make the test on hemiamyloidity in the meantime? I have yesterday found that Lopadostoma gastrinum has a hemiamyloid apical ring, though quite dirty reddish in IKI but deep blue in KOH + IKI. I am unaware of a literature report and I assume that in Melzer without KOH the reaction is quite negative. The specimen is from Aix-en-Provence, on Ulmus.

Si c'est sur Corylus, pourquoi pas Allantoporthe decedens ?

Re:Pyreno on Corylus (Alnus?) bark
Merci, Jean-Pierre
I don't know this species, but Munk's description says: ' spores with a delicate, fugacious, rounded appendage at each end'.
The spores of my collection are very different, as you can see.
Enrique
Jean-Pierre Lafont, 28-07-2009 11:48
Re:Pyreno on Corylus (Alnus?) bark
OK Enrique you are right. Since it can be either on Corylus or on Alnus, I can hazard another guess: Cryptodiaporthe pyrrhocystis?

Re:Pyreno on Corylus (Alnus?) bark
Good night, Jean-Pierre
Some time ago, I think Alain Gardiennet suggest me this species that I don't know. I don't have aditional information about her. Only Ellis & Ellis's drawings, that show me very different appendages.

Re:Pyreno on Corylus (Alnus?) bark
Bonjour à tous,
Je ne me souvenais plus t'avoir soufflé ça Enrique, mais si Paul Leroy te le suggère, tu peux considérer la piste très sérieuse.
D'autant plus que ce soir, j'ai repris la description de ce taxon par Wehmeyer, cela colle parfaitement à ta récolte. Peu de Cryptodiaporthe ont des appendices pareils.
Je pense que tu peux oser faire une fiche car c'est une récolte intéressante pour qui veut s'intéresser aux Diaporthales.
Si Luis Mejia pouvait y jeter un oeil, nul doute qu'il serait d'accord ou du moins espérons le.
Alain
PS : Salut Paul ! Toujours pas trouvé de pyrénos sur les cadavres de tiques ?
J'ai pensé à toi ce soir, j'en avais une mais j'ai réussi à mater ma tique... :)

Re:Pyreno on Corylus (Alnus?) bark
Bon soir:
Alain, as tu la description de Wehmeyer que tu me dites? Peus tu m''envoyer une copie digitale?
Merci a les deux!
Enrique
