Sur Abies. Spores 7-9 x 0,8-1,2 µm. Peut-être vers O. auricolor ?

Thanks Zotto ...

Re : Orbilila rouge

SAlut Patrice,

Compares avec O. rubrovacuolata, une espèce assez présente dans tout l'ouest.

Le support en revanche est moins habituel il me semble.

Re : Orbilila rouge

Yes! and conifers are possible (Picea, Pinus). Abies is a new host. I assume A. alba?

Could you tell me the place? We have samples from Vendee but but from more south, except for Asturias! So there is a big gap in Poitou, Aquitaine, and Basque.

Patrice TANCHAUD, 19-02-2019 17:12

Re : Orbilila rouge

Probably Abies nordmanniana. Les Essouverts commune de LOZAY (17). Zotto, you think as Michel, it is O. rubrovacuolata wtih these paraphyses ?

Hans-Otto Baral, 19-02-2019 17:17

Re : Orbilila rouge

yes of course, no other Orbilia has red vacuoles.

Do you have coordinates? Was it a branch or a log? The date?

Patrice TANCHAUD, 19-02-2019 20:59

Re : Orbilila rouge

18 fév. 2019, LOZAY Bois des Essouverts, altitude environ 80 m.
Coordonnées : 46.029528, -0.517052
On a tree trunk rotting on the ground.

Not easy to see beautiful vacuoles in paraphyses.

Thanks Michel and Zotto.

Re : Orbilila rouge

Great, thanks! The "conidies" do not belong to the fungus.
Michel, you never found the species in Deux-Sevres?

Michel Hairaud, 19-02-2019 22:40

Re : Orbilila rouge

Not yet , Zotto, but this collection is only about 10 kilometers from the Deux Sèvres border. ..

Re : Orbilia rouge

Keep an eye on dead Rubus stems Michel . . . . I now have a number of records on Rubus fruticosus agg. and one on R. idaeus (October-March).

Chris

Michel Hairaud, 23-02-2019 12:59

Re : Orbilia rouge

Oui, cher Chris, merci pour tes encouragements.

I also already found it on Rubus stems but in other areas though I try hard to conserv R. fructicosus in my garden -:)
