Bonjour à tous, Une récolte sur bouse séchée d

This species was growing on bark of Betula.
Is my determination correct?
Thx in advance,

Hello,
definitely - what makes you hesitate?
best regards,

Hi William,
oh, I didn't intend to be annoying ...
I was asking because I had some difficulties last summer in identifying H. mulitforme on Carpinus because the young stromata gave a brighter KOH reaction than described in pyrenomycetes.free.fr - but it was H. multiforme nevertheless. So it might be important to know that the young stoma yield a more orange reaction compared to the olivaceous-yellowish reaction of the mature stomata.
best regards,
Andreas
