Just FYI in case anyone else is reasearching this algae, Bob Fenner said this algae isn't Lobophora. He said it's
Peyssonnelia sp, An encrusting Red. Class
Rhodophyceae, Subclass Florideophycidae, Order Gigartinales, Family Peyssonneliaceae. I asked him why he was able to rule out Lobophora and he said the following:
"A few things... one is that this and most browns don't do well in captive systems unless they are administered
iodine/ide/ate... in quantity, regularly... Another, that it does not look "soft" as this genus almost always appear in aquariums... and lastly, the very distinctive "ring-like" growth of Peyssonniella. "
