Witches' butter and bracket

[Morchella]

Haven't found Exidia glandulosa before so pleased to (I think!) see it today growing on a dead trunk in a hedgerow in Roding Valley Meadows Nature Reserve.


Also found these brackets growing on a very soggy log in a ditch - no hope of IDing the tree but having looked through Rogers my best match seems to be Trametes pubescens - it was definitely slightly hairy - although I'm, not sure that it's typically coloured. The last photo shows the pore surface of one that I removed and turned over.




Would be grateful for any help

I think you are right for 1, but I suspect 2 is stereum hirsutum.
Cheers

1) exidia glandulosa
2) stereum hirsutum

[Morchella]

Oh yes, that looks more like it. Completely missed it because it was described as a fungus that doesn't form brackets.

Last time I mistook a Trametes for a Stereum - maybe third time lucky!

hi Laura

a clue is that the 'pore surface' doesn't have any pores . . . that's an important character in what is often an extremely difficult area (bracket and 'resupinate' fungi) - even with a microscope it often becomes merely very difficult!

now you've found the Exidia you will probably find that you see it much more regularly (it kinda works like that) so keep an eye out for its parasite - see the thread http://www.wildaboutbritain.co.uk/fo...es-butter.html

good hunting

Hallo Chris,

but this one looks more like Exidia plana and the parasite only grows on Exidia glandulosa if I understood that right?

B.t.w., in Germany we have the common name "witches butter" ("Hexen-Butter") also. It is used only for Exidia plana - and quite often also for the myxomycete Fuligo septica ...

best regards,
Andreas

Hi Andreas

to be honest I never even enlarged Morchella's photo . . . I just trusted the others' ID's

the two species are presumably quite close genetically and so it is not impossible that it occurs also on E. plana; there are so few records that perhaps the host range of Heteromycophaga is not yet fully circumscribed

übrigens . . . have you found it yet? you've had your two weeks - or is the weather in Thüringen as unwelcoming as ours? (though something tells me that you are all rather better prepared than we Brits!!)

best wishes

Chris

Oooppps ... trapped .....
I have not had any walk in the forest those two weeks. And to be honest, the weather is not very convincing for interesting findings. During the day temparature goes up to a few degree above zero, but all nights are frozen. Not exactly the climat where you suspect abondant fungi growth outside ....

I hope I get another 2 weeks chance ...

best regards,
Andreas
