Loreleia
Orange Red Loreleia ( Loreleia postii )
The Loreleien ( Loreleia ) is a fungal genus from the order of bristle -like Scheiblingkirchen of unknown parentage, whose species form nabelingsartige fruiting body with happy orange and hygrophanen hats. Despite the similarity with the navel rings ( Omphalina s.str. ) The Loreleien are not closely related to them. For example, neighborhood include the equally happy pigmented orange Orange Red Heftelnabeling ( Ricke Ella fibula ), but also fungi with completely different fruit body types, such as the blood red bristle Scheiblingkirchen ( Hymenochaete cruenta ) or the Purple Zystidenkeulchen ( Alloclavaria purpurea).
The type species of the Loreleien is the Orange-Red Loreleia ( Loreleia postii ).

Features
Macroscopic characteristics
The vaulted to spread out, depressed hat has a smooth surface and a rounded or straight edge. The diameter is 2 to 25 mm. Depending on the humidity, the hat color ( hygrophanous ) and the fins on the bottom changes seem to be more or less than scoring with an orange hat skin. The rather thick than thin lamellae run on a stick down, have a medium to remote distance from each other and a white to yellowish color. The spore powder makes a white imprint. The 5 to 70 mm long and 0.5 to 2 mm thick stem has a smooth and at the top of a frosted stem bark and is colored orange. Both the smell and the taste are nonspecific.
Microscopic characteristics
The spores are smooth, thin-walled and transparent ( hyaline ). Show with the addition of Iodreagenzien no color reaction, can not be with cotton blue stain ( acyanophil ) and discolor upon contact with dissolved in water Kresylblau not reddish or purple ( not metachromatically ). The spores stand ( basidia ) develop each (2 -) 4 spores. Cystidia absent on the lamellae ( Cheilo and pleurocystidia ), as well as on the hat ( Pileozystiden ). On the stem bark they are ( Caulozystiden ), however, present. The Hutdeckschicht ( Pileipellis ) is constructed as cutis. The fungal threads ( hyphae ) do not have buckles on the cross walls ( septa ) in the entire fruiting body.
Ecology and phenology
Loreleien live either saprobiontisch of mosses or are viable only with liverworts. In the latter case, the fungus penetrates into the rhizoids of the liverwort and is able to form with it a kind of symbiosis. However, the liverwort Loreleia ( Loreleia marachtiae ) had in pure culture the inoculated wells liverwort ( Marchantia polymorpha ) killed; as opposed to natural resources without necrosis.
The fruiting bodies appear in the spring to autumn.

Origin of the name
The scientific genus name " Loreleia " has no connection with the famous slate rock on the Middle Rhine (see Loreley ) but is of the American mycologist Lorelei Norvell Lehwalder dedicated for their research with nabelingsartigen agarics.
