CHROOLEPUS AUREUM (L.) Ktz.  c. 
This alga is seldom classed with the marine. But a favorite 
habitat is on the spray-moistened cliffs and the branches of trees 
and shrubs that overhang the sea, forming patches of a striking 
crimson yellow. It is one of the few alge found growing out of 
water, and yet not quite independent of that element, as it requires 
a moist air.
