A fucus or seaweed much used in the East for soups and jellies; Ceylon moss ({Gracilaria lichenoides}). [1913 Webster] 2. A gelatinlike substance, or a solution of it, prepared from certain seaweeds containing gelose (such as Ceylon moss, {Gracilaria lichenoides} or other seaweeds of the genera {Gelidium}, {Ceramium}, {Pterocladia}, and {Eucheuma}), and used for solidifying growth media in the artificial cultivation of bacteria, or as a gelling agent in foods; -- usually called simply {agar}, by abbreviation.
