Witches' Butter

Exidia sp.


Another Exidia species found in our oak forest, first in the series. This one takes an irregular shape of a gelatinous, dark-brown to black, lump protruding through a deep layer of old moss on a large log discarded in the forest. The lump is very jelly-like, shaky on touch, and appears covered in wart-like bumps. This lump was about 10 to 12 cm large, some 5cm deep, and about the same in height.


One of three Exidia species, recently found on deadwood scattered on forest floor, in a lowland broadleaved (mainly oak and birch) forest, in Geneva lake valley. This one was clearly protruding from the thick layer of moss covering the bark of a large decaying llog.


I can only hope that my ID down to the genus was right - I'm getting a bit confused about the identification of these fungi, and find that there is not much about them in terms of literature...
