Synnemata on Russula
Alain GARDIENNET, 04-10-2017 20:05
Alain GARDIENNET

Hi forum,


I can't identify this hyphomycete on old black Russula.


White synnemata less than 1mm, with subglobose conidial mass,  producing ciliate hyalin aseptate conidia, 6-7 x 2 µm, with 4-11 µm long appendages .

Re : Synnemata on Russula
Those are some really good photos. I wonder though if they aren't pycnidia? It looks like the masses of conidia are emerging from a peridium of hyaline tissue?

Re : Synnemata on Russula
salut Alain,
je pense que Jason a raison. Un synnema est porté par un stipe, souvent long, constitué d'hyphes en palissade qui se différencient en cellules conidiogènes au sommet.
Il faudrait voir aussi à quoi ressemblent les cellules conidiogènes, qui se trouvent peut-être à la base de la pycnide.
Une coupe longitudinale de la pycnide s'impose! ça t'apprendra à lorgner les Russules!
Amuse toi bien,
Jacques

Re : Synnemata on Russula
Yes. Determining what type of conidiomata you have will direct you to literature specific to that type. For instance, when we have pycnidia or acervuli we can turn to Sutton's The Coelomycetes. Fungi imperfecti with pycnidia, acervuli and stromata. 1980. Best - J

Re : Synnemata on Russula

Bonjour,


I only find time to answer.


I will do again new microscopy, probably on sunday. I can show you now another picture corresponding probably to the top of synnemata-like.


Alain

Re : Synnemata on Russula
Hello Alain,

I do not have a speciesname for you,but the synnemateous fungi, the genera, are nice3ly discribed in "Genera of hyphomycetes ", from Seifert and Gams  and so.

Best,

Marco

Re : Synnemata on Russula
Hi Alain,
look at Eleutheromyces subulatus. Grows, amongst others, on Russula and blackens the basidiomata.
Cheers,
Hermann

Re : Synnemata on Russula

and the winner is... Hermann ! Congratulations.


Here are cells of conidiomata wall.


Thank you to all, especially to Hermann, of course.
