Description
Species Description - Plants red- or yellow-brown. Stems branching by innovation, up to 25 mm high, rounded-triangular in section, with rhizoids sparse. Leaves often distant, erect-spreading, twisted and occasionally incurved when dry, spreading when moist, narrowly channeled, 1—2.5(-4) mm long, long-oblong, occasionally wasp-waisted, broadly acute, apiculate, the base oblong, sheathing; margins plane or weakly reflexed above a sheathing base, entire or distantly dentate above; costa percurrent to short-excurrent, dorsally papillose, the ventral cells quadrate and papillose or elongate and smooth; upper cells quadrate, strongly papillose; basal cells strongly differentiated within, about as wide as upper cells or m o r e commonly inflated, mostly 2-4:1, thin-walled, elongate along the margins. Dioicous. Setae ca. 12-15 mm long, 1(2) per perichaetium; µm ca. 1.5 mm long, cylindric, usually curved, often almost as short as the operculum, with a rigid suboral ring of 4-5 rows of thick-walled cells; annulus of 1-2 rows of vesiculose cells; operculum to 1.3 mm long, short-conic; peristome divisions rudimentary to short-linear, ca. 100-250 µm long, spiculose or ridged, lacking a basal membrane. Spores ca. 14-16 µm, weakly papillose.

The sharply differentiated, often highly inflated basal cells, similar to those of Calymperaceae, are a salient feature of this species. T h e basal cells of B. recurvirostrum m ay occasionally be somewhat inflated, but this species has narrower leaves and a straight capsule. W h e n the basal cells of B. campylocarpum are only weakly inflated, it has m u c h the appearance of B. jamesonii, in which case other characters mentioned in the key may be used to distinguish the two species.
