228 Haynes: THE GENUS SPHAEROCARPOS 
early instead of remaining permanently in tetrads, in its subglobose 
archegonial involucre with a small orifice, instead of being long- 
tubular with orifice the diameter of the involucre. In both ot 
these species the foot remains attached to the capsule on the de- 
tachment of the latter from the thallus ; the spore markings are 
somewhat similar. In S. Donnellii, the spores separate at maturity, 
their markings are areolate instead of typically cristate, and they 
are characterized by a coarsely lobed basilar margin. 
The description and drawings published by Professor Camp- 
bell in his ‘‘ Notes on Sphaerocarpus” (Erythea 4: 73-77. 1896) 
probably relate chiefly to this species.

Archegonial thallus suborbicular to oblong, 2 mm. in diam- 
eter, in thick cushion-like tufts, light green when dried, margin 
divided into 4-8 cuneate, ascending, somewhat undulating lobes, 
marginal cells generally quadrate, averaging 26-39 #; archegonial 
involucres 1.5~2 mm. high, distinctly stipitate (the slender stipes 
0.5-0.65 mm. long), tubular-ovoid, ellipsoidal, or bluntly conical, 
more or less narrowed to the truncate apex, fleshy, carnose- 
Opaque, its wall apparently more than one cell thick, orifice 
large, of nearly the diameter of the involucre, setulose, the hyaline, 
thick-walled setulae mostly 2 cells long, incurved : antheridial 
thallus not seen: capsule 340-420 # in diameter; the persistent 
spore-tetrads yellowish, coarsely areolate and somewhat rough- 
ened, marginate. [PLATE 32
