XVII. Naccaria. Endl. [Bate 20, U.] 



Frond c^'lindrical or compressed, filiform, solid, rose-red ; 

 central cells large, empty, those of the surface minute. Ra- 

 w^^//^ composed of jointed, dichotomous, whorled filaments, 

 surrounded by free gelatine, Frxictijication : spores, attached 

 to the whorled filaments of the (swollen) ramuli. — Name, in

 Eastern and southern shores of England and Ireland, and west of Ireland. 

 Usually thrown up from deep water. — Frond 6 — 12 inches high, cylindri- 

 cal, filiform, much branched ; main stem about half a line in diameter, 

 attenuated upwards, repeatedly divided with alternate branches spreading 

 quadi'ifariously, the branches thickly set with minute, slender ramuli, ta- 

 pering to both ends, and from about half a line to a line and a half in 

 length. Structure of stem and branches cellular; the ramuli composed of 

 minute, dichotomous, gelatinous filaments, radiating from the centre. 

 Colour a fine rose-red, given out to fresh water. Substance tender and 

 gelatinous, adhering to paper. Fructification situated in the centre of the 

 ramuli, which are then much swollen ; consisting of numerous minute red 

 spores, attached to the whorled filaments of the brauchlet. 



XVIII. GLOIOSIPHONIA. Carm. [Plate 21, A.] 



Frond cylindrical, filiform, tubular, somewhat gelatinous ; 

 the periphery composed of radiating, coloured, branched, 

 jointed filaments. Friictijication : globules of red spores 

 ffarellidiaj imbedded in the filaments of the periphery, to 

 which they ai'e attached. — Name, yKoiog, viscid, and aKpcov, a 

 tube ; from the gelatinous, tubed frond. This genus, founded 

 on the FticHS capillaris of Turner, was originally proposed 

 by the late Capt. Carmichael, in his unpublished Algoi Appi- 

 nenses, and has been adopted by Mr. Berkeley. Except in 

 the tubular frond it does not differ from Mesogloia.
