Nectria-like fungus on stromata of Nemania sp.
Enrique Rubio, 21-01-2014 19:13

Hi to all


Can you help me, with this scanty information, with these small perithecia growing on copious white subiculum on the stromata of Nemania sp.? I don't know the anamorphic stage neither the structure of the perithecial walls (I like very much my fingers!)


The KOH is negative and the asospore walls have coarsely cianophilic striate walls


Any idea?


Many thanks again

Hi Enrique,


It's absolutely amazing !


It looks like Protocreopsis, doesn't it ?


But Protocreopsis species are generally tropical.


P. pertusa has striate ascospores measuring 13-17 x 4-5 µm.


It's a fungus for specialists.

I hope that this fungus won't be rejected in the dustbin !

Re : Nectria-like fungus on stromata of Nemania sp.

Thank you Alain


I have considered Protocreopsis, but as you says it seems to be a tropical genus


I'm waiting for some response of the specialist people 


Thanks!

Hello Enrique.

No setae on ascomata ?

No, Yannick. Absolutely no setae

Re : Nectria-like fungus on stromata of Nemania sp.
Hi to all,
Protocreopsis is a herbicolous genus, it is not fungicolous. It would be useful to know the thickness of acomatal wall because the only genus that could match is Nectriopsis. Nectriopsis has thinner ascomatal wall that Protocreopsis, it is an important characteristic.
Enrique, to know thickness of ascomatal wall the section does not need to be very thin.

Regards,
Christian

Hi Christian


I cannot make it better with four fingers that stay in my hand!


I think the perithecial wall is about 20 microns

Re : Nectria-like fungus on stromata of Nemania sp.
Sorry to answer so late,
this specimen is confusing... it is not Nectriopsis, I think it is maybe the genus Stilbocrea.
I must cultivate and sequence it to know where the molecular data place this species.
Could you please to send me a part of your collection?

All the best,
Christian

Re : Nectria-like fungus on stromata of Nemania sp.

OK., Christian


I'll send you it

Hi Christian, hi to all


Today I have collected again this fungus growing on wood but this time with unknow relations. Have you new notices for it?


Thanks in advance
