Is this Black Witches Butter - Exidia glandulosa?

[VixS]

At first I thought I may have done my usual trick of finding a deceased fungi, until I was trying to identify other fungi's from my Markeaton Park foray.



According to Michael Jordan's 'Encyc of Fungi' it fits the description perfectly, but when looking online all I can find under this name is the brain like folds which Micheal Jordan says is Exidia plana.

I came to my conclusion that it is Exidia glandulosa becasue of the disc/cup-shaped fruiting body as well as the contorted brain like folds (but not as brainlike as the pic he has of the plana)

Please help
Thanx

An extract from the Checklist of the British & Irish Basidiomycota has this to offer on Exidia glandulosa :

"Habitat: On dead attached or fallen wood of deciduous trees, most commonly Corylus, Quercus spp. and Fagus.

Notes: Common and widespread. Basidiomes are turbinate, unlike those of E. plana which are resupinate and cerebriform. Exidia glandulosa sensu Fries (1823) is the latter species."

FoS has E. plana as a synonym for Exidia glandulosa.

All a bit confusing but I would go along with your conclusion Vix.

Hi Vix

The top species in your photograph looks like Bulgaria Inquinans

That would fit, it was on a fallen oak!

Good spot FJ - FoS indicates that the black colour of the hymenium of B.inquinans, often confused with E. glandulosa = E. truncata, rubs off when stroked with the finger.

I think you could be right - I would never have ID'd it from my books but after searching the rogets online, they are practically identical!

Thank you John, I think I may be changing my ID!

Spore colour should be the clincher;

B. inquinans - dark brown
E. glandulosa - colourless
