I'm no expert but I think it's what is known commonly as Witches Butter.

Hello,
not sure to which fungus the english term "Withces Butter" belongs to, but the German equivalent is used for either the (black) Exidia plana oder the slime mould Fuligo septica. But your fungus is Tremella mesenterica or Tremella aurantiaca, for which (at least in Germany) the name Witches Butter is not used. Might be in Britain it is other, but I think also here Exidia plana is ment with that name.
bestr egards,
Andreas

In Britain Witches Butter is the name given to E.glandulosa, and Yellow Brain given to T.mesenterica.
Forestelf,
It is not possible to know which species of Tremella you have here because it is not possible to know which fungi it is growing with, so you either have T.aurantia or T.mesenterica.
(T.aurantia is parasitic on Stereum hirsutum, and T.mesenterica is parasitic on species of Peniophora.)
Neil.

Hello Neil,
I think we mean the same species for Witches Butter. Exidia glandulosa is a name formerly used for Exidia plana and nowadays used for Exidia truncata (if they haven't changed it again ...). I think Wítches Butter is the name for Exidia glandulosa-plana ...
best regards,
Andreas

The problem with all reference books (mine being no exception) is that they very quickly become out of date and such are the pressures on publishing profits that frequent revisions are not economically possible.
To clarify the position, the current British Checklist has Exidia glandulosa as the preferred taxon version, but not Exidia truncata other than as a synonym of E. glandulosa. | | | |
