Leiocolea badensis, Tunnel Row Forestry, Abergwynfi
The calcicole community also included, among others, Calliergonella lindbergii, Ctenidium molluscum, Dicranella varia, Ditrichum gracile and Encalypta streptocarpa.
Leiocolea badensis resembles L. turbinata but differs in the very obvious broad attachment of the leaves. It is less easy to see that the leaves are also shortly-decurrent until you get a shoot under the microscope.

In Smith's key, leaf cell dimensions are used to differentiate badensis from turbinata, but Paton warns that the variation in cell size in both species makes this an unsatisfactory criterion. Better to look for the small, but rather obvious trigones in the leaf cell structure of L. badensis.

Leiocolea turbinata is a more strict calcicole and unlikely along forestry tracks.
We also collected a round-leaved Jungermannia sp. (without perianths), which was locally abundant, but remains unidentified.
