Proposed Names

Recognized by sight: The species of the genus Tremella live parasitically on other fungi. T. mesenterica is tapping Peniophora species. Often you could find the fruitbodies oft the host on the same branch, which contains the fruitbody of T. mesenterica. Another sometimes very similar species is T. aurantiaca. This species shows more yellow-orange, usually thicker fruitbodies which grows on thicker substrate. Furthermore the fungus lives parasitically on Stereum hirsutum.

Everything takes place in the substrat

No fruitbody of the host is needed to know there’s one. The two fungi interacts inside the branch. There the hyphae of the Tremella (parasite) is tapping the hyphae of the Peniophora species (host) with haustoria.

In Wikipedia you could find a list of some species with their hosts:

Interesting——has it consumed its host in these photos??

I didn’t see any other obvious fungi on the branch and these certainly appeared to be a single species rather than a morphed shroom. Since it was slightly opaque, it would have been easy to see any host within.

Just curious what your thoughts are…
