L. marchantiae L. postii L. roseopallida Loreleia is a genus of brightly colored agarics in the Hymenochaetales that have an omphalinoid morphology.

[3] However, the large number of DNA base-pair changes causes a long-branch to form in phylogenetic analyses depicted as cladograms.

[6] Loreleia penetrates the rhizoids of liverworts and may form a type of symbiosis with them,[7] but in axenic culture tests, L. marchantiae killed Marchantia polymorpha when directly inoculated[8] in contrast to the absence of necrosis in nature in situ.

In nature Loreleia often occur in wet areas such as seepages with their hosts, Marchantia.

Older literature often treats the species, like L. postii and L. marchantiae, in the genera Omphalina or Gerronema.
