Hymenoscyphus dans P. lentiscus
Javier Ormad, 06-12-2009 20:21
Bonjour à tous!
Je présente une possible Hymenoscyphus sur tiges morts de Pistacia lentiscus. Le plus grand diamètre de 1,5 mm à pied jusqu'à 2 mm. Les spores n'ont pas de cils ni cloisons et mesurée 14-21 x 3.5-4.5 microns. Suite à la clé de Ellis & Ellis, je pense que pour obtenir à H. vitellinus, mais sont un peu étroit des spores.
Avec les variétés de H. scutula, et leur tendance s'observe aussi loin de spores, mais je ne vois ni cils, ni cloisons, pourrait écarter cette espèce?
Merci d'avance

Dear Javier

clearly a Hymenoscyphus. Are you sure the substrate is twigs? It looks like it could also be petioles? Then your fungus could be H. caudatus s.l. Important is to look for the ascus base. If you still have the fungus fresh you should also look for the living paraphyses for their contents. The asci you figure are dead, perhaps you find living ones which are much larger.

H. scutula has likewise aseptate spores when mature, the septa develop later.

Re:Hymenoscyphus dans P. lentiscus
Petiole not proper, but the stems that attach to the leaves. But the color of the apothecia becomes yellow and not white or cream as described in Ellis & Ellis. The spores believe mature and I think the content of paraphyses is greenish with vacuoles, septa and without terminal enlargement.
H. caudatus is a good choice and P. lentiscus could be another host, but did not rule H. scutula if the septa and the cilia are very mature spores. I have a fresh specimen ........
Thanks
