Trentepohlia sp.

Trentepohlia is a genus of filamentous chlorophyte green algae living free on terrestrial supports such as tree trunks and wet rocks or symbiotically in lichens. The filaments of Trentepohlia have a strong orange colour caused by the presence of large quantities of carotenoid pigments which mask the green of the chlorophyll. There are a number of similar species and we treat them as a species aggregate due to difficulty of identification.

Found on terrestrial supports such as tree trunks and wet rocks or symbiotically in lichens.

All year round.

Widespread in Britain with most records appearing to come from the far north.

Status in Leicestershire and Rutland not known.
