4. ANTHOCEROS FUSIFORMIS Aust. Bull. Torr. Bot. Club, 6: 28. 
< 1875. 
Thallus in depressed rosettes 6-20 mm. in diameter, or often 
suberect and caespitose in tufts 5-20 mm. deep, thick and rather 
rigid, opaque and blackened when dry, undulate-crisped, deeply 
and irregularly dissected, ecostate, cavernose within, 10-25 cells 
thick in median parts, becoming rather abruptly 3- or 2-stratose at 
margin, often with large and abundant glandular-thickenings, more 
or less lamellate-cristate, lacunose, the lamellae sometimes broad 
and leaf-like ; surface-cells somewhat distinct, subquadrate to ob- 
long-hexagonal, 30-75 и x 18-40 и, with large chloroplast, inner 
cells much broader and longer in axile and basal parts, but often 
scarcely larger toward the growing apices : monoicous : antheridia 
in groups of 2—4: involucres often numerous and crowded, but 
very rarely with the bases united in pairs, subfusiform or narrowly 
cylindrical, often curved, 2-9mm. х.35-1.2 mm., smooth, furrowed, . 
or rarely lamellate, mouth repand or scarious and erose-lacerate: cap- 
sule dusky brown to black, 2-0 cm. (mostly 3-6 cm.) х.25-.5 mm., 
rather long-pedicellate, valves commonly a little twisted on drying, 
stomata abundant, the guard-cells nearly colorless ; spores dark- 
brown or black, 45—63 и in maximum diameter, angular, the con- 
vex face with very numerous (125—225) spines or papillae less than 
3 р in length, plane faces granulose-papillate or sinuate-foveolate ; 
pseudo-elaters fuscous, 60-250 их 8-14 и, ОҒ 1—4 cells, genicu- 
late and variously contorted, sometimes branched.
