Re : Black spherical pyrenomyces on coniferous wood

I would suggest Bertia moriformis, but spore measurements not quite right. See: http://fungi.myspecies.info/all-fungi/bertia-moriformis

Best wishes

Re : Black spherical pyrenomyces on coniferous wood

Hi Chris

Thanks.
So far I did not know that Bertia moriformis can grow on coniferous wood.
I added more photos of spores. It reminds me a little Bertia moriformis var. latispora

Best wishes

Palo
