This is Bonfire-moss (Funaria hygrometrica) which has now come to its end leaving this deep red colour.
Rear garden, Staffordshire, England. June 2017.
This can be quite an untidy-looking plant, especially when in abundance with long, 3-5cm swan-neck setae. The short 3-10mm green shoots form loose carpets. The egg-shaped leaves vary in size from 2-4mm long, and are translucent.
It is a colonist of bare, disturbed ground enriched with nutrients, and is particularly characteristic of old bonfire sites, hence its common name. Frequent and widespread throughout Britain.
