The green and yellow gelatinous cap ( Leotia lubrica ) is a fungus from the order of the Helotiales . As saprobiontic this fungus feeds on dead wood dead deciduous and coniferous trees .
features
Macroscopic properties
The mushrooms are clearly stalked with an abruptly detached convex head with a curved, wavy edge, on the upper side of which the hymenium is formed and which is between 0.5 and 4.0 cm wide. The color varies between green-yellowish and olive-brownish, the underside is lighter. The gelatinous consistency is typical. The head feels sticky and slippery in damp weather. The meat is gelatinous and translucent.
The stalk becomes 2–8 cm long, the diameter is 3–10 mm, and it is slightly thickened towards the bottom. The stem surface is either smooth or scabby to the touch due to tiny granules on the skin; in damp weather it becomes slimy. The stem is similar in color to the hat, but is usually lighter and more yellow. The inside of the stem is hollow and filled with a slimy gel.
Microscopic properties
The 16–25 × 4–6 µm large spores are hyaline, smooth, elongated-sickle-shaped and have four to seven septa. The asci are cylindrical-clubbed and are 140–160 × 8–10 μm in size. The paraphyses are filamentous and partially branched.
Ecology and occurrence
The green and yellow gelatinous cap occurs under both coniferous and deciduous trees and breaks down dead wood. The fruiting bodies are formed from late spring to autumn and sometimes grow underground, they have also been discovered under sand dunes.
The occurrence extends over North America as well as Central Europe.
meaning
The green and yellow gelatinous cap used to be considered edible. In the meantime, the toxin monomethylhydrazine has been detected in the fungus (5 mg / kg). Thus, the species is at least suspicious of poison.
