Apophlaea is a genus of thalloid algae that is endemic to New Zealand.[1] Species in the genus are found in the high intertidal zone on New Zealand's coasts.[2][3] Specimens can reach around 15 cm in size. The thalli take a crustose form, but also contain upright, branching frond-like protrusions that reach 5–8 cm in height.[4][5] Secondary pit connections and secondary pit connectionsare present in the organisms. Apophlaea reproduces by means of conceptacles; it produces tetraspores.
It is notable for its symbiotic relationship with certain fungi.[6] Despite its unusual morphology, molecular systematics, along with its zoned tetrasporangia borne in conceptacles with a single opening, place it within the Hildenbrandiales.[7]
The algae are resistant to both U-V radiation and desiccation, allowing them to thrive in intertidal settings.[8] Indeed, they can resume almost full photosynthesis just minutes after losing 95% of their tissue water.[9]
Species
There are three species in the genus Apophlaea:[10]
- Apophlaea darchinoae Webby, Thorn & M.Preuss, 2022
- Apophlaea lyallii J.D.Hooker & Harvey, 1855
