hamadryad IME and of course this i have yet to evaluate with a scope, T mesenterica tends to degrade in a less soggy state, and does not go white nor transluscent in age and in fact actualy dries to a deeper brighter hue of orange,found in association with peniophora quercina predominantly on fine deadwood, whereas the easily degraded aurantia which is found on more solid wood volumes and in association with Stereum hirsutum predominantly tends to degrade into a white to translucent jelly. 11-05-11

Thanks for info & update.

Fungus David,
According to the latest research findings (Der Tintling 4 (2009), Sauter & Haedeke. Tremella aurantia : ein Doppelgänger des Goldgelben Zitterlings Tremella mesenterica, pages 81-84), you may be right, the problem however is, that herbarium collections from before 2009 have not (always) documented whether T. mesenterica was found on Peniophora or Stereum species or both, and most mycologist where not (yet) familiar with T. aurantia, so we have to "restart" from scratch to identify both species and the substrates of T. aurantia and T. mesenterica before a definit answer can be given. Based on my own observations and research, I am not yet convinced, that one can identify both species by their hosts.		 08-05-11
hamadryad T mesenterica feed off peniophoras, it is T.aurantia that feeds of the stereums, is it not? 08-05-11
Fungus David,
For a photo of this phenomenon, see my Album : Beech : Nectria ditissima Trametes gibbosa.
The same succesion can occur with Trametes versicolor being followed by Lenzites betulinus, which sometimes also starts as a parasite of the mycelium of T. versicolor and with Jelly fungi, such as Tremella encephala on Stereum sanguinolentum and T. mesenterica on other Stereum species.		 05-05-11
Monkey-D T. gibbosa following on from Bjerkandera is something that is new to me. I will watch out for this.

thanks Gerrit		 04-05-11
Fungus David,
Correct, so I agree on all photo's showing Trametes gibbosa. On beech, T. gibbosa is often preceded by Bjerkandera adusta, on the mycelium of which T. gibbosa lives as a parasite and as a saprotrophic successor, further decomposing the wood. The brackets of the fungus present on the vertical saw cut of the beech however seem to be of Chondrostereum purpureum.		 04-05-11
hamadryad Daedaleopsis would be breaking through bark, I am sure that these images are T. gibbosa. 03-05-11
Monkey-D Gerrit,

the under bracket (pore) shots of pic 2 & 3 are from underside of pic 1 taken from the cut surface of a severed fagus limb.		 03-05-11
Fungus David,
Both photo's showing pores colouring reddish to pink brown when touched or damaged depict Daedaleopsis confragosa.
