Bloody Hypoxylon!?
Dartanha Soares, 11-04-2016 23:18
Dartanha SoaresHi to all,
Found this one on decorticated wood (unknown), but I did not have much time to work on it.
Ascospores are 12.5-14.5x5.6-6.5 micra, with sigmoid germ slit (full spore length), perispore dehiscent.
What called my attention was the "red-blood" pigment on KOH 10%.
Any hint will be welcome.

Hi Dartanha,
this is strongly suggesting H. lenormandii but the red pigments in KOH are indeed deviaiting from those encountered in typical H. lenormandii. It is worth a more detailed study.

Cheers,

Jacques

Re : Bloody Hypoxylon!?
Hi Jacques,
Thank you very much.
I looked at Kuhnert et al. paper (Fungal Diversity (2015) 71:165–184) and it fits well. They mentioned that this fungus "have Blood colour (3) and Dark Vinaceous (84) pigments in KOH", and is already reported from Brazil (a single specimen collected by Rick in 1906!!).
But as you said, it deserves further studies, since according to them "H. lenormandii" seems to be a species-complex.
Once again, thank you very much!!
