Identification notes
If you are bryologising near the sea you may come across what appears to be T. caucasica (formerly modica) with obtuse leaf apices and a yellow seta.
This is likely to be Tortula pallida, a species only added to the British list in 2021. Older taxonomies include this plant variously as a variety of Pottia intermedia, P. littoralis or P. pallida and it wasn’t until 1993 that it was transferred to Tortula as T. pallida.
