Microcoleus & Lyngbya

October 24, 2000
From: Clay Carlson

Bill,
I think what you said about Lyngbya and Microcoleus is reversed. Microcoleus is the older term. It has apparently turned out that there were a number of species lumped as M. lyngbyaceus. One of these is now called Lyngbya majuscula.

When I asked Dr. Roy Tsuda what was going on, this is the answer I got.
"Lyngbya majuscula (Dillwyn) Harvey is just one of the 100's of species which Dr. Francis Drouet lumped under Microcoleus lyngbyaceus. Lyngbya majuscula is the large blue-green (green, black or red in color) which can be found in shady areas, e.g., under coral ledges on the reef flat, or on the sandy bottom of the murky Cocos Lagoon. It is unique; however, it can be difficult to differentiate from a few other Lyngbya."

If you notice in your list of references, the earlier names are Microcoleus, the last 1998 article uses Lyngbya. Since some of these forms co-exist, this could explain why we have what we thought was so many of the haminoeid forms feeding on the same algae/bacteria.

Dear Clay,
Thanks for correcting me. I must admit I was puzzled by the date anomaly in the reference list but had been following Richard Willan's earlier message on Bursatella leachi.
Best wishes,
Bill Rudman.
