Parmelia hypoxantha, Sirz. Thallus pale-yellowish or whitish (K yellow), 
usually orbicular, medium rough, laciniate, with small imbricate laciniw, margins: 
erenulate and sinuose-lobate, bluish-black, shortly and sparingly covered with. 
black fibrils. Medulla white (K-C-). Apothecia brown, 2-4 mm. wide, flat. 
margins often crenulate. Spores 8, colourless, simple, broadly ellipsoid, 009 — 
‘012. x ‘007 — ‘009 mm. ; paraphyses not easily separable,'apices rufo-fuscescent, 
hypothecium colourless. On bark. , 
The lower surface of the medulla (exposed after the black hypothallus 1s 
peeled off) is almost always seen yellow or orange-yellow, and K gives, on this: 
surface, a yellow then red reaction. 
This Parmelia is certainly closely allied to P. subtiliacea (Nyl. Lich. N.Z.,. 
1889, p. 26), but the spores in five different samples examined are as given above ; 
while those of P. subtiliacea are ‘(014—°017 x (007 — 008 mm., and the thallus 
“albidus.” Krempelhiiber describes (Novara Exp. p. 114) a Parmelia under 
the name P. Jelinekii, which is also allied to the present one. Its thallus is 
“ ochroleucus,” and the sub-medullary stratum is “lete aureum,” but the spores: 
are exactly as given above under P. subtiliacea, perhaps a little longer.

Pannaria elatior, Strn. Thallus broadly foliaceous, pallid, testaceous, often 
orbicular, epithallus minutely granulose or leprose, particularly towards the: 
margin, laciniate, lacinis incised and albo-sorediate along the margin, beneath: 
ale fawn-coloured or whitish, covered with long white or occasionally blackish. 
brils. Apothecia reddish-brown, flat, girded with a white, rather prominent, 
radiate-rugose thalline margin, spores 8, in one series, colourless, ellipsoid or 
fusiform-ellipsoid, 015 — 019 and -008 — ‘01 mm. ; paraphyses separable, 
medium; hypothecium colourless, with iodine cerulescent. Strathbrook, near’

Pannaria terrestris, Strn. hallus pallid or pale-green, thin, squamose, of 
small appressed scales of about 3 mm., margins crenate, the lobes crowded or’ 
distinet ; gonimia bluish, small, -003 — 005 mm., in large oblong heaps, with 
distinct margins, width to ‘08 mm. Apothecia medium, lecanorine, sessile, 
brownish-red, margin pale, with a prominent finally crenulate margin, spores 8, 
colourless, simple, ellipsoid or broadly ellipsoid, ‘012 — 016 x 007 — ‘009 mm. ; 
paraphyses medium, ‘fairly discrete, with clavate conglutinate red and brow? 
apices ; hypothecium yellowish-red or almost colourless ; hymenial jelly, with. 
iodine bluish, then wine-yellow or reddish. On bare earth. ‘ 
This lichen is somewhat anomalous. I cannot recall any Pannaria having. 
gonimia (which are of a brilliant blue) contained in such large distinct mem- _ 
branes. ‘These glomeruli vary from ‘01 to ‘08 mm. long, and may contain 
hundreds of gonimia. Dr. Nylander has constituted a new genus or subgenus: 
of Lecanora under the name of Lecanorina, whose thallus contains gonimt
