filaments branch laterally from the subterminal cells or by subdichotomous division 
of the terminal cell (fig. 42 H). The cells are somewhat various in shape, usually 
longer than broad, and contain a stellate chromatophore with central pyrenoid which 
is usually situated in the median line of the cell, sometimes however nearer to the 
one side of the cell. The hairs appear in various quantity, sometimes already in 
the parenchymatous stage (fig. 42 A). The erect filaments, if they are not entirely 
wanting, appear in 
rather small num- 
ber spread on the 
disc; I have found 
them one to three 
cells long, scarcely 
4, thick. The spor- 
angia are placed di- 
rectly on the basal 
dise or terminal 
on the erect fila- 
ments; they were 
not very numerous 
in the specimens 
examined.

12. Chantransia polyblasta sp. nov. 
Thallus cæspitulosus. Pars basalis e filis repentibus, ramosis, initio saltem 
inter se discretis, constructa. Spora germinans dissepimento verticali diametrali 
in duas cellulas aequales dividitur, quarum utraque filum repens procreat. E 
filo primario lateraliter fila repentia et sursum fila erecta numerosa per totam lon- 
gitudinem egrediuntur. Fila erecta usque ad c. 270 longa, maxima ex parte brevia, 
longiora ramosa, ramis ramulisque numerosis in quoque articulo singula vel bina, 
ramis majoribus eodem modo ramosis. Pili hyalini apicibus filorum et ramulorum 
impositi occurrunt. Cellule 7—10y crassæ, diametro 2—3 (—4)-plo longiores, chro- 
matophorum stelliforme, pyrenoide centrali instructum, continentes. Sporangia te- 
traspora, ovata, (16—) 18—21 » longa, 10—-12 „ lata, in filis erectis primariis vel 
in ramis lateralia vel terminalia, lateralia sessilia vel in ramulis unicellularibus 
vulgo singula.
