This species closely resembles C. holocarpa (described elsewhere) but differs in the thallus and prothallus, both of which are black. The spores in C. atroflava are broad (13–16 x 9–10µm) with a wide septum (5–7µm). It grows mainly on shingle pebbles. In Ireland, there is a record from County Donegal. Material recorded from County Galway is now considered doubtful.
