I never really thought this was Lichenomphalia, but I don’t know Arrhenia. Note the algae all around the base, but it’s not granular like it should be with L. umbellifera (= L. ericetorum… the “correct” name differs depending on whether you talk to lichenologists or mycologists, apparently). Note also, that this occurred on the same log as a huge population of Multiclavula mucida.

The plot thickens…

Irene, here’s an MO obs IDed as Lichenomphalia that appears to be a very good match for Jason’s obs (116828).

Checked a bit online, and Omphalina ericetorum is reported as a preferable synonym for L. umbellifera. So I’m supposing that the specimen seen in this obs IS fungal.

Beautiful photos…

of a really interesting… mushroom? Very interesting genus, Lichenomphalia. Does it fit into the Kingdom of Fungi?
