Ascotremella faginea sur Acer campestre ?
Bernard CLESSE, 31-10-2015 22:40
Bernard CLESSEBonsoir à tous,

Récemment j'ai trouvé ce que je pense bien être Ascotremella faginea sur branche morte d'érable champêtre (Acer campestre).

J'ai cependant un petit doute car je m'aperçois que les asques sont faiblement IKI + !! Or, apparemment dans la littérature, on met IKI- pour cette espèce.

Les spores, ± fusiformes, biguttulées sont finement striées en long mais quasi impossibles à photographier : 9,5-12x3,5-4

Qu'en pensez-vous ?

Bernard

Hi Bernard,


this ist correct - Ascotremella faginea.

Good evening Lothar and thank you for your confirmation !

Is it also means that you agree to asci IKI + in this species ?

Hi Bernard

I think I saw this species only amyloid. See my drawing.

Maybe you can alspo see in your specimen that the asci have no croziers.

It is quite long ago that I saw A. faginea myself. I suppose that it is more closely related to Ombrophila/Neobulgaria than to Ascocoryne, with which it was confused (var. foliacea is = faginea, based on my type study HB 6431).

There is bad need in sequencing of ombprophiloid fungi, including Ascotremella. So if you want you can send Guy Marson a portion.

How certain is the substrate? I actually had it mostly on Fagus. Did you take a piece of wood with you?

Hi Zotto,


Ascotremella (it is not too rare) grows on a lot of deciduous substrata, and rarely also on conifers. Acer campestre (if correct) is thus not very surprising.

Re : Ascotremella faginea sur Acer campestre ?
Hello Zotto,

I am glad that you also found that amyloid asci are. I watched your drawings and that is exactly what I saw!


I've already found several Ascotremella faginea but several times on other trees than Fagus: Quercus, Carpinus, ...


Yes, my Ascotremella faginea is on a piece of wood (Acer campestre).


OK to send it to Guy Carson, can you give me their contact information ?

Sent you a mail. Just please give me the collection data which I finally need also for the sequence.

Thanks!

Re : Ascotremella faginea sur Acer campestre ?
Hi Bernard

as you know, yesterday Guy sent the sequence of your Ascotremella. It confirms my suspicion that the fungus is much closer to Neobulgaria pura than to Ascocoryne, which is already obvious when doing a BLAST in GenBank. Now I am hoping for more sequences of Ombrophila in order to clarify whether Neobulgaria can be taken as congeneric with Ombrophila.
