Trentepohlia algae

Trentepohlia sp.


Trentepohlia is a genus of filamentous chlorophyte green algae but Trentepohlia species 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.
