Loreleia is a genus of brightly colored agarics [1]in the Hymenochaetales that have an omphalinoid morphology[1][2][3]. They inhabit mosses and or liverworts on soil in temperate regions of the Northern Hemisphere. Phylogenetically related agarics are in the genera Contumyces, Gyroflexus, Rickenella, Cantharellopsis and Blasiphalia, as well as the stipitate-stereoid genera Cyphellostereum and Cotylidia[4] and the clavaroid genus, Alloclavaria[3]. However, the large number of DNA base-pair changes causes a long-branch to form in phylogenetic analyses depicted as cladograms. In the field, to the eye, Loreleia is most similar to Rickenella because of the orangish colors and omphalinoid shape, but microscopically it differs by the absence of cystidia that in Rickenella make the latter minutely fuzzy as seen with a hand lens[5]. Loreleia penetrates the rhizoids of liverworts and may form a type of symbiosis with them[6], but in axenic culture tests L. marchantiae killed Marchantia polymorpha when directly inoculated[7] in contrast to the absence of necrosis in nature in situ.
Older literature often treats the species, like L. postii and L. marchantiae, in the genera Omphalina or Gerronema.
[edit] Etymology
Loreleia was named after the contemporary American mycologist, Lorelei L. Norvell, who studied omphalinoid agarics.
