Fig. 207. PHYLLOPHORA BRODI^I. 
Colour. A bright, clear, pinky-red. 
Substance. Delicately membranaceons, but rigid. Stems elastic. 
Character of Frond. Cylindrical stems becoming flat and narrow wedge-shaped, or oblong, 
upwards ; forked or simple ; throwing out frondlets from their upper margin. 
Frondlets at first cylindrical ; soon expanding into oblong or wedge-shape ; simple 
or forked, throwing out secondary frondlets from their tips. This second set 
throwing out a third in the same way, and so on. 
Measurement. From 1 to 8 inches long. 
Fructification. Of two kinds. 1. A mass of spores in globose capsules^ sessile on the tips of 
the frondlets. 2. Tetraspores formed in warts^ of nearly the same size as the 
capsules., but stalked. 
Habitat. Eastern coast of Scotland. Belfast Bay. On rocks in the sea. Bare. 
For another Phyllophora, see Plate L. Fig. 228, to which the smaller form in the present 
figure (207) refers. Phyllophora palmettoides is a subdivision of plants which were once classed 
together under P. Brodiai ; and the dark sorus here figured is peculiar to P. palmettoides. 
Fig. 208. FURCELLARIA FASTIGIATA. 
Colour. Brownish-purple ; often nearly black when picked up, and becoming so on drying. 
Substance. Solid ; strong ; opaque ; elastic, but fleshy. 
Character of Frond. Cylindrical, smooth ; repeatedly forked, from a short taper stem ; thicker 
above than below ; the forkings long and narrow, all the angles of branching {axils) 
being acute. Boot a mass of fibres. Fruiting in winter. 
Measurement. From 6 to 12 inches long. 
Fructification. Of two kinds. 1. Masses of spores (/aveZZtp) imbedded in the swollen upper 
forkings. 2. Tetraspores deeply imbedded in the same. 
Habitat. Our coasts generally. On rocks within tide-marks. Common. 
When in fruit the upper divisions are swollen into a lanceolate pod-like form ; somewhat 
flattened in shape.
