rugulose, broader towards top, hairy about tip; hairs short, patent; mouth 
small, contracted, much tuberculated at base, springing from frond in pairs, 
greenish-white at first, brownish-white in age. 
Hab. Epiphytieal on Hookeria (sps.) and other mosses and Hepatice, 
but easily separated ; growing low down in sides of dark water-courses, hill 
forests, near Norsewood, County of Waipawa; 1883-84: W.C 
Obs. A species near to A. orbiculata, and imbricata, mm1: “ Trans. 
N.Z. Inst.," vol. xvi., p. 859. 
Genus 89. Anthoceros, Micheli. 
1. Anthoceros pellucidus, sp. nov. 
Plant prostrate, spreading, effuse, 2-6 inches diameter, densely imbri- 
cate, thin, transparent, fragile, crumpled, minutely tuberculate, light green, 
cells large, nerveless, with a few very fine rootlets at the extreme base: 
fronds 4—14 inches broad at top, mostly narrow at base, sub-flabellate, more 
or less branched or deeply laciniate at top, irregularly lobed ; lobes largely 
crenate or rounded at tips, margins free, sub-erect, finely and irregularly 
torn and sub-fimbriate; some fronds are very narrow, j-2 lines wide, pin- 
natifid (like Anewra multifida). Involucre stout, conical, finely tubercu- 
lated near base, generally 8 or more arising from centre of a frond, 1-2 
lines high, lips sub-bivalve, scarious. Capsule linear very narrow, almost 
filiform, arcuate, 8 lines long, light brown, dehiscing centrally on both sides 
and then margins reflexed, cohering at tips; columella exceedingly fine ; 
spores light brownish-green; elaters large, numerous. Gemma, little 
oblong dark green bodies immersed and scattered in the frond. Appar- 
ently the seeds and filaments are at first contained in a thin transparent 
membrane around the columella, which is soon ruptured. 
Hab. On rotten logs in dark wet woods, spreading over and adhering 
to other small Hepatice, mosses, dead twigs, etc., near Norsewood, County 
of Waipawa; 1882-84: W.C. 
Oxver VII. LICHENES. 
Genus 5. Spherophoron, Persoon. 
1. Spherophoron vividulum, sp. nov. 
Thallus sub-esspitose, with a few small scales at the base, erect, flat, i 
1-1} inches high, main stem 1-8 lines wide and unbranched below, sub- 
palmate and dichotomous above, very smooth and slightly convex on the 
upper surface, rugulosely pitted on the lower, edges entire, whitish beneath, 
light green above when living, but a dull olive-green when dried ; upper 
branchlets numerous, very narrow sẹ- inch wide, sub-linear-clavate, 
ultimate segments cuneate-truncate, obconie, and spathulate, narrower at 
bases, having a sub-articulated appearance like some species of Corallina. 
Apothecia very small on slightly raised hemispherical receptacles just below
