T. mesenterica - habitus
The golden-yellow to honey-yellow mushroom has 3 to 10 centimetres (1.25 to 4 inches) in diameter. It's gelatinous and has many convolutions and ridges. Thereby, the mushroom looks like a small, yellow brain, which is also the reason for names like “Yellow Brain”.
The dry mushroom is only a thin organe layer on the wood. It gets his brain-like habitus only by becoming wet.
The spores are egg-shaped and has a messurement of 7-11 x 7-9 micrometres. The sporepowder is white or pale yellow.
T. mesenterica - on a branch
T. mesenterica is a parasite, which infects other fungi. These hosts are wood-decomposing fungi, which grows on the wood of angiosperm trees like alder, acer or beeches. The species is a cosmopolitan and can be found all over the world.
Unlike the allegation in some literature, this fungus is not poisonous and edible. However, the tough, rubber-like mushroom has no special flavor and tastes very insipid.
