Pyrophyllon subtumens

Pyrophyllon subtumens is an obligate red algal epiphyte of Durvillaea southern bull-kelp, and is endemic to New Zealand.

[1][2] The species belongs to a monotypic genus, which is sister to Childophyllon - a genus containing another red algal epiphyte of other seaweeds in New Zealand.

The species was previously recognised as Porphyra subtumens before being reclassified.

[2] The species can be found growing on all mainland New Zealand species of Durvillaea.
