The beautiful white fungal filaments sprouted from an oak branch covered with a corticioid fungus. The branch/stick was left in a humid box mixed with six other pieces of wood covered with different corticioid fungi species. Only the oak branch with the orange corticioid fungus sprouted the white filaments. None of the others sprouted any white filaments. Interesting. Were the white filaments growing ON the corticioid fungus and were not part of it?

An asexual ascomycete growing on a corticioid?

Dr. Rich Baird, a plant pathologist from MS State, believes that the white feathery structures in the photos is an asexual ascomycete, specifically a “synnema” structure, growing on the basidiomycete corticioid.

The Exidiopsis video is interesting

It shows something that looks similar. But they talk of Exidiopsis forming on cold (freezing?) nights and subsequently “melting.” The specimens here fromed in a damp box at room temperature and lasted a couple of weeks.

Delicate but did not melt to touch

Richard Hanlin (UGA) believes it was the corticoid fungus that began to “grow out,” perhaps an asexual stage.

I don’t know what that means, but it doesn’t change anything from the previous comment.

Again, the documenttions and intelligence of some members, gives better results than imposing a microscope!

very filamentous

and grouped into distinct projections. I highly doubt this is an “ice beard,” as Alain calls it, if not for the reasons just mentioned, then for the fact that our uploader surely touched the things he observed, and they did not melt in his hand. if he did not, they did not proceed to melt upon being brought indoors and left there long enough to submit to photography.

I have seen things resembling this elsewhere on the site, and the only genus I know of that looks anything like it is Anthina, an anamorphic ascomycete genus. the only species I have seen in photographs is A. flammea, which is considerably more brightly colored than this (this has no color whatsoever).

a microscope, as always, could be of great help. then again, it could be of no help. either way, I firmly believe this to be fungal.

Thank you for these fantastic images.
