Few sporangia have been seen but none of them appears to have 
any such diverticula and rhizoids as have the sporangia of G. 
polyrhiza. The sporangia are also smaller than those of С. 
‚ polyrhiza, rarely exceeding 50 in longest diameter. Gomontia 
arhiza was described by Hariot from Tierra del Fuego. G. 
polyrhiza has been ascribed to the American North Pacific by 
Saunders (Proc. Washington Acad. Sci. 3: 415. 1901) and by 
Setchell and Gardner (Univ. California Publ. Bot. 1: 229. 1903).

Endoderma strangulans sp. nov. 
Endophytic in cell walls, at first filamentous with irregular 
mostly monopodial branching, forming finally a compact pseudo- 
parenchymatous thallus of indefinite extent and often wholly 
encircling the host plant, this disc occasionally 2 or 3 cells thick 
either falsely by the presence of subjacent filaments or actually by 
cell divisions in the tangential plane, filaments of the disc margin 
free, interwoven, or more or less anastomosing; cells 6-18 и wide 
(averaging то и), mostly irregularly subquadrate or trapeziform, 
occasionally triangular, those of young filaments often 2—6 times 
longer than broad, the apical frequently curved, those of the more 
compact parts of the disc often elongate vertically (radially in 
relation to the host), obovoid, subpyriform, clavate, fusiform, or 
conic-cylindric, sometimes 24 и high; pyrenoids 1-4 (usually г); 
most of the cells of the disc at length becoming sporangia with 
little change in size or form, though commonly developing a short 
conical beak-like apex; spores 8-64 (?) to a sporangium. [PLATE
