Snow Fungus

Tremella fuciformis


Tremella fuciformis is whitish or nearly transparent, and fairly large - up to about 7 cm across - and it features graceful gelatinous lobes rather than the glob-like blobs that typify so many other jelly fungi. Tremella fuciformis has a life cycle that is intertwined with that of another fungus; in this case an Ascomycete in the genus Annulohypoxylon or Hypoxylon. It is unclear whether Tremella fuciformis actually parasitizes the Hypoxylon, or whether there is a complex symbiosis or mutualism involved. It grows as a slimy, mucous-like film until it encounters its preferred hosts and then invades, triggering the mycelial growth required to form the fruiting bodies.


It may be found on hardwood logs in tropical or subtropical areas after heavy rains


This log had a large clump approximately 6” to 7” across, and several small clumps/colonies. The log was in a north-facing location that would remain more moist/humid.
