Memnoniella echinata ?

Bonsoir forum,


J'ai trouvé sur graminée des amas (sous forme de petits coussinets) de conidies brunes fortement échinulées, subglobuleuses avec un diamètre proche de 12 µm. Les conidiophores sont morts.


Pourrait-il s'agir de Memnoniella (ex. Stachybotrys) echinata ?


Je n'y crois guère, mais je ne sais dans quelle direction chercher.


Alain

Re : Memnoniella echinata ?
Cher Alain, Non, c´est une espèce d´Arthrinium, mais je ne sais pas laquelle.

Re : Memnoniella echinata ?
It certainly does not look like any of the Arthrinium species in Martin Ellis's Mycological Paper 103 (1965) - perhaps it is undescribed?

Re : Memnoniella echinata ?

Hi nocturnal mycologists,


You're right, it fits better with the genus Arthrinium : macroscopically it reminds me, and the colour of conidiospores fits well, conidiogenese too. But I've never seen a such shape for ascospores in that genus. But if the specialists that you are don't know it ...


Thanks to you for help. I keep  on the side this Arthrinium sp. ("echinata").
