Dear Shannon,

Although the photos only show the macroscopic form, you are most likely
seeing an outbreak of several species of red algae, including *Liagora*, as
well as the normally very rare *Liagorothamnion*, the type specimens which
I discovered in Puerto Rico growing abundantly in shallow water on the back
reef and reef flats after Hurricanes Hortense and Georges. This
unusual species must exist as an alternate cryptic/ microscopic phase until
a hurricane hits, and which point it blooms abundantly and reproduces

The paper describing the algae by Huisman et al, 2001 is at this link-
