This species was growing on bark of Betula.


Is my determination correct?


Thx in advance,

Re : Hypoxylon multiforme?

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
