I suspect that I might be in the wrong genus, but I can’t seem to find a better alternative. Where have I gone wrong? 
First an overview of the thallus:

Section of a perithecium:

“beaked” pycnidium with columnar macroconidia:

“aberrant” pycnidium with grey mass of conidia:

Close up of what I believe to be microconidia, but I am unsure if that is indeed what it is (1 div. = 0.96 µm):

Have you tested the pycnidia walls with K, they should be K + olive green far all AnisomeridiumAnisomeridium polypori
Neil
The wall of the perithecia and both the conical and “abberant” pycnidia react K+ green/olive. It seems, however, that the globular “conidia” develop secondarily on the concial pycnidia – and that they occur in “chains”. I found a pycnidium with normal conidia on the inside, but with the grey mass on the outside. While I have no explanation for that phenomenon(a lichenicolous fungus, perhaps?), I am satisfied that the species in question is A. polypori.

Thanks again for helping and for welcoming me.
