Black Witches' Butter

Exidia glandulosa


Another Exidia species found in our oak forest, third in the series. This one takes an irregular shape of a gelatinous, dark-brown to black, somewhat ear-like lumps growing from decaying larger branches and logs. These lumps do not touch, and are a less jelly-like on touch than the previous species; they are a bit firmer. This biggest form here was less than 10cm large.


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 log.
