Range & Status
Epiphytic on the decaying leaves of Zostera spp. in the lower intertidal and shallow
subtidal zones. This rarely recorded summer annual forms tiny, erect, filamentous shoots on Zostera blades. The recent demise of the intertidal Eelgrass Zostera spp. beds in Cornwall will have done little to enhance the success of this species. It is known only from a few scattered localities around the British Isles.
