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

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

The only known species is Endogemma caespiticia (Lindenb.) Konstant., Vilnet & A.V.Troitsky.

The family Endogemmataceae, the genus Endogemma and the lone species Endogemma caespiticia were all published by Konstant., Vilnet et A.V.Troitsky in Folia Cryptog. Estonica 48: 132 in 2011.

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. Schuster.

The name Endogemma is derived from endogenous (originate from within a living system) and gemmae (single cell, or a mass of cells in asexual reproduction). This is a very rare feature in hepatic plants. The species epithet of caespiticia is derived from caespiticius meaning made of turf.

It is commonly known as the delicate flapwort, or carpet-like flapwort.
