Macroscopic features
The annual fruiting bodies are mostly sticking out from the substrate , only rarely are they fully attached. Often several hats sit on top of each other. They are semicircular and have a firm, gelatinous consistency. The top is hairy. The hymenophore on the underside is yellowish-orange in color and has a wrinkled-reticulate or sinuous-ribbed structure with cross connections (merulioid). Sometimes it appears almost poroid. The fruit layer ( hymenium ) not only covers the supposedly protected pits, but the entire surface including the raised folds. The meat ( trama ) has 2 layers (dimitic).
Microscopic features
The hyphae structure is monomitic. The hyphae themselves are hyaline and heavily branched. They have buckles on the transverse walls ( septa ). Lepto Zystiden are few available. They are smooth or partially encrusted. The narrow, club-like spur stands ( basidia ) stand in a dense palisade. They are also hyaline and have a buckle at the base. The small, cylindrical-sausage-shaped spores are smooth, hyaline, thin-walled and show no color reaction ( inamyloid ) when iodine solution is added . They are 3.5–4.5 × 1–1.5 µm in size.
Species delimitation
The gelatinous folds can hardly be confused with other species. Characteristic are the wrinkled underside, the hairy upper side and the tough-pliable consistency.
Ecology and phenology
The gelatinous folds can be found in deciduous and mixed forests as well as all kinds of corresponding forests, if these are not too dry. Medium-moisture beech, hornbeam, oak and alluvial forests are preferred. Occasionally it can also be found in parks, gardens and similar biotopes. The fungus lives as a saprobiont on lying, mostly debarked trunks and branches as well as on stumps. It causes white rot in the wood . Hardwoods, mostly red beech, are primarily colonized . It rarely grows on coniferous wood.
The fruiting bodies appear mainly in autumn from September to November. If the conditions are right, they can be found all year round.
distribution
The gelatinous fold is widespread in the Holarctic in North America, Europe, Siberia and Japan as well as in India. In Europe, the area extends from Great Britain, France, Portugal and Spain in the west eastwards to Poland, the Czech Republic, Slovakia and Hungary. To the north, the area extends to the Hebrides as well as Fennoscandinavia and Lapland .
In Germany the fungus is common to common everywhere. There are only a few thinning areas.
