Bernard CLESSEUne idée sur ce Mollisia (du moins je suppose que le genre est bon…) ?

Paraphyses : KOH -

Hi Bernard
in order to verify Mollisia I need to see the living paraphyses. 
What is te diameter of the disc?

Hello,


did you check the porus reaction with Lugol (or Barals) in water, without KOH pretreatment?


Hairs and spores look like Mollisia (Haglundia) elegantior, which would fit also macroscopically. But this species would have blue porus reaction only in low IKI concentration and is red in higher concentration.


best regards,
Andreas

Hi Zotto and Andreas,

Thank you both for your messages !

The diameter of apothecia is : 2 mm

I made several photos of the paraphyses in the water but I can not send them for the moment because of computer problems: their upper half has a refracting content but that does not go to the end.

All mature spores are uniseptate.

The porus reaction was only made in the Baral liquid (IKI 2-6) and than without KOH pretreatment.

Best regards,

Bernard

Re : Mollisia sur grosse branche pourrie et décortiquée de chêne
So I agree with Andreas, it could be Mollisia elegantior which gets 1-septate spores when overmature but which has an inrolled margin which might disappear only when late in age.

Good evening Zotto and Andreas,

Just for your information, some more photos I had made on this Mollisia.

Best regards,

Bernard
