Falkenbergia rufolanosa

Asparagopsis armata is a marine red algae species. It was first described in 1855 by Harvey, who found the algae on the Western Australian coast.[1] Native to the Southern hemisphere, it has been introduced to the Northeastern Atlantic Ocean and the Mediterranean Sea.

Its life cycle has two distinct phases:[1]

  • the gametophyte phase occurs in Europe between June and September. It is pale purple-red, and it has 1 mm wide and up to 200 mm long irregularly branched thalli. The lower branchlets have characteristic harpoon-like barbs.
  • the tetrasporophyte phase (previously identified as Falkenbergia rufolanosa) occurs in Europe all year round. It is brownish red, branched and filamentous and grows in 15 mm diameter tufts.
