Synematous microfungus forming Coral-like structures

Hi, here I am writing again about another strange fungus growing on the bark of a dead tree that I suspect is Ficus carica. First seen, it looks like a dry coral mushroom with a pale beige-ink color. It grows in tufts and then it apparently blackens out. Under the microscope, it turned out to be a synematous microfungus composed of sterile structural core of thick entangled hyphae, mustard-brown to curry-brown in color but dull. This becomes black in KOH. The outer layer is a thick dense coat of penicillate hyphae, with branches arranged in whorls and each subbranch seems to have a small head of phialides each producing one conidiospore. Conidiosore bean-shaped. This layer is pale mauve (almost greyish) and turns dirty green in KOH. The conidiospores are cream-straw color and become mauve-pink in KOH.

any clues please?

Thank you xxxx

I will investigate and let you know. To tell you the whole story, I think when its life is over it deposits as a black layer on the bark, on which an interesting Cosmospora s.l. sp. (cf flavoviridis) later grows upon. I really wish to solve this puzzle so many thanks for your guidance.

I skimmed over the paper - very, very interesting and the pieces are fitting nicely together. This fungus seems quite close to Hypoxylon or Biscogniauxia anamorph, which then becomes a black stroma - the sexual state - on which the Cosmospora grows on (assumingly on the dead stroma, but not sure). Today I will investigate at high power the condiophores. Biscogniauxia forms black stroma on bark so we are getting close!
