 PHYLLOPHORA BEODI^I.— /. Ag. 



Gen. Char. — Frond flat, rigid, nerveless, uniformly cellular ; cells minute, roundish 

 angular. Fructification: "1. Tubercles (favellidia), scattered over the surface 

 of the frond, and containing a mass of minute roundish or angular spores ; 



2. Warts (nemathecia), seated on the frond, and composed of radiating monili- 

 form filaments, whose lower articulations are at length converted into spores ? 



3. Tetraspores, on distinct plants, collected into sori, either towards the apex 

 of the frond, or in proper leaflets." — Harvey. Name from (piXKov, "a leaf," 

 and (popiw, "to bear." 



Phyllophora Brodicei. — Stem filiform, cylindrical, branched, the 

 branches expanding into a thin membranaceous, obcuneate, simple or 

 once divided frond, repeatedly proliferous from the extremity ; tubercles 

 (nemathecia) spherical, sessile at the apices of the leaflets.

Description. — Root, a small spreading disc. Stems somewhat elongated, 

 cylindrical and filiform, one and a-half to six inches in leng-th, sparingly 

 branched, the branches expanding upwards into thin, membranaceous 

 frondlets, which are oblong or obcuneate, simple or once or twice forked, 

 with romided axils and rounded or bifid aj^ices ; generally repeatedly 

 proliferous, with leaflets of similar form, and often have their apices 

 fringed with minute -.-leaf-like processes. Structure celkdar ; central cells 

 small, hexagonal, those at the surface very minute, all more or less highly 

 coloured. Substance rigid, not adliering to paper in diying. Colour,
