The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.

Dasya corymbifera



Range & Status

A large (to 10cm), robust polysiphonous species confined to the subtidal zone and deep rock pools. It is difficult to distinguish from other Dasya spp. unless fertile, but it is also very rare. At the present time it is known from the Isles of Scilly, the north coasts of Devon and Cornwall, Dorset and the west coast of Ireland. There is evidence to suggest that it may have undergone decline in recent years.
