Trentepohlia aurea


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 very similar species and identification to family level should only occur after detailed examination of the specimen, otherwise they should be recorded as an aggregate.

Identification difficulty

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

When to see it

All year round.

UK Status

Seems to be most frequent in north western Scotland. Exact status in Britain is difficult to determine to the difficulty of species identification.

VC55 Status
