Endogemma is a monotypic genus of liverworts belonging to the family Endogemmataceae and subclass of Jungermanniineae.

[2][3] The genera Endogemma and fellow Jungermanniineae subclass genus Solenostoma was also accepted by Borovichev 2014,[4] and Konstantinova & Lapshina 2014.

[1] It has the beaked perianth mouth of Solenostoma and a lack of perigynium and shoot calyptra as in Jungermannia species.

It differs from similar Solenostomataceae and Jungermanniaceae species in having endogenous gemmae and in a characteristic large, single oil-body otherwise only known for Solenostoma tetragonum (Lindenberg) R. M.

[2] It has a creeping to ascending form, with endogenous gemmae concentrated in unfertilized perianths (flower parts).

Rhizoids (protuberances that extend from the lower epidermal cells) are dense to scattered and colour-less to brownish in shade.

They are in indistinct obliquely spreading fascicles commonly closely attaching plant to the substratum or soils.

On the North American side, it seems to be quite rare and is recorded only in British Columbia and Alaska and also eastward also known from rather isolated locality near New York.

In the Russian Far East, it occurs mostly below 500 m a.s.l., with rare exceptions confined to anthropogenically modified habitats such as in Iturup Island (1020 m a.s.l.
