Ah, then this could be a funny looking Rosellinia, and the white could be a particularly appressed subiculum. Another genus with hundreds of tropical species distinguished mostly by ascospores. The white, tightly appressed subiculum, the large size of the perithecia, and the rough surface texture might narrow it down, though. There’s a great treatment of the genus by Liliane Petrini published in 2013; I’ll poke through it.

Substrate and size

Yes, each black round thing seems to be a single perithecium. The pale material very likely a part of this (or another?) fungus. They were quite small. 0,6 cm to 0,8 cm across.

Whoa!

Those are cool! What’s the scale for these photos? I’m interpreting each black round thing as a single perithecium, about 1mm across? Is the pale material part of the wood/substrate, or part of the fungus?
