"Loreleia" is a genus of brightly colored agarics [http://www.nahuby.sk/obrazok_detail.php?obrazok_id=34358] in the Hymenochaetales that have an omphalinoid morphology [cite journal | author=Redhead, S.A. "et al." |year=2002a | title=Phylogeny of agarics: partial systematics solutions for bryophilous omphalinoid agarics outside of the Agaricales (euagarics)| journal=Mycotaxon | volume=82 | pages=151–168] [cite journal | author=Redhead, S.A. "et al." |year=2002b | title=Phylogeny of agarics: partial systematics solutions for core omphalinoid genera in the Agaricales (euagarics)| journal=Mycotaxon | volume=83 | pages=19–57] cite journal | author=Dentinger, B.T.M. & McLaughlin, D.J.' |year=2006| title=Reconstructing the Clavariaceae using nuclear large subunit rDNA sequences and a new genus segregated from "Clavaria"| journal=Mycologia | volume=98 | issue=5 | pages=746–762| doi=10.3852/mycologia.98.5.746] . 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"cite journal | author=Larsson, K.-H. "et al." |year=2006 [2007] | title=Hymenochaetales: a molecular phylogeny for the hymenochaetoid clade| journal=Mycologia | volume=98 | issue=6 | pages=926–936 | doi=10.3852/mycologia.98.6.926] and the clavaroid genus, "Alloclavaria". 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 [cite journal | author=Norvell, L.L. "et al." |year=1994 | title="Omphalina" sensu lato in North America. 1-2: 1: "Omphalina wynniae" and the genus "Chrysomphalina". 2: "Omphalina" sensu Bigelow| journal=Mycotaxon | volume=50 | pages=379–407] . "Loreleia" penetrates the rhizoids of liverworts and may form a type of symbiosis with them [cite journal | author=Bresinsky, A. & Schötz, A.|year=2006| title=Behaviour in cultures and habitat requirements of species within the genera "Loreleia" and "Rickenella" (Agaricales)| journal=Acta Mycol.| volume=41| pages=189–208] , but in axenic culture tests "L. marchantiae" killed "Marchantia polymorpha" when directly inoculated [cite journal | author=Kost, G.|year=1988| title=Interactions between Basidiomycetes and Bryophyta|journal=Endocytobiosis Cell Res| volume=5| pages=287–308] 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".

Etymology

"Loreleia" was named after the contemporary American mycologist, Lorelei L. Norvell, who studied omphalinoid agarics.
