Striaria attenuata is epiphytic and occurs on the fine red algae Melanothamnus harveyi and on Polysiphonia.

This species was found growing as as an epiphyte on the fine red algae Melanothamnus harveyi in the millpool at West Looe, Cornwall, 17.02.22.

The specimens found did not posess any unilocular sporangia so it was not possible to fully determine the species. However on examination the axis were hollow which means that the species was unlikely to be Stictyosiphon soriferus which it can be confused with. In Holland Striaria attenuata has also been found as an epiphyte on Polysiphonia.

I am grateful for the assistance of Frank Zeewieren.

AlgaeBase is a database of information on algae that includes terrestrial, marine and freshwater organisms.

The main objective of this website is in furthering environmental awareness and education through the medium of photography. To increase awareness and access to the wildlife of the region and help

people find and identify it. Sometimes the difference between species is obvious but many species can only be determined by observing microscopic characteristics that are specific to any one species.
