Lopadostoma on hardwood

Hi to all


These pulvinate erumpent stromata grew on corticated wood of Quercus robur. The very polymorphic and aberrant ascospores are mostly in 4-spored asci. It could be the Lopadostoma dryophilum of the recent paper of Jaklitsch, Fournier. Rogers and Voglmayr?


Thanks again

Hi Enrique,


Have you read the last paper in Persoonia 32 ?

Hi Alain


Yes. I have the paper. I have doubts because 'my' stromata have a reddish tissue between the perithecia and the asci are mostly narrower and 4-spored


Thanks!

Re : Lopadostoma on hardwood

Yes, and ascospores also don't fit with described species.


You should contact Jacques or Walter...

Re : Lopadostoma on hardwood
Hi Enrique and Alain,
the second photo shows some white tissue above the perithecia, thus I think that L. dryophilum can be ruled out.
It should be assessed if all asci are definitely 4-spored, which would be highly distinctive, or if only a variable percentage of asci are fortuitously 4-spored. Such asci are more frequent in hardly mature perithecia and may be responsible for abnormal ascospores. Enrique, try to find 8-spored asci and make measurements of ascospores, their length range should be smaller and more informative.
Cheers,
Jacques

Re : Lopadostoma on hardwood

Hi to all


Jacques, je vais t'envoyer mon materiel avec l'autre Lopadostoma similaire au gastrinum, avec blanchatre endostroma, que nous avions trouvé sur Quercus ilex.

Re : Lopadostoma on hardwood
D'accord Enrique,
envoie moi les deux, c'est vraisemblablement la même espèce.
Merci
Jacques
