Coccocarpa molybdxa, Pers. 
Placodium clavigerum, S7rn. Thallus pallid or pale-yellowish, appressed, the:

or yellow-brown (K. purp.), lecanorine, flat or sub-conyex, medium ; spores 8, 
colourless, oblong or oblong-fusiform, polari-bilocular, ‘009 — 013 x -004— 
‘005 mm. ; paraphyses discrete, with colourless apices, clavate and articulate, the 
club-shaped tips ‘004 — -005 mm. wide; hypothecium colourless. Hym. 
with iodine bluish; gonidia large ‘009 — -02 mm. broad. On bark. 
Lecanora subpurpurea, Sfr7. Thallus pale-yellowish or testaceous, rather 
rough (K- C- golden-yellow) ; apothecia black, sessile, within wholly purplish- 
violet, margin pale and roughish ; Spores 8, simple, broadly ellipsoid, ‘(008 — 
‘O11 x -006 — -007 mm. ; paraphyses thick (breadth 004 — -005 mmm.) ; apices. 
scarcely clavate ; hypothecium colourless. On bark. 
Lecanora pheoplaca, Strn. Thallus ashy-pale, rough or granulose, rimose- 
diffract (K- C-) ; apothecia, sessile medium, width 1-2 mm. or less, brown,. 
flat, with a pale entire or crenulate thalline margin; thee spored; spore 
colourless, ellipsoid or oblong-ellipsoid, 5-septate, rarely 5-7 locula, with 
thick hyaline walls, ‘0: — -09 x -022 — -03 mm. ; paraphyses slender, discrete, 
with brown granulate apices ; hypothecium colourless, blue with iodine. On. 
bark. In the pale border are numerous small cells, ‘006 — -01 mm. wide, which 
appear as leptogonidia, often clustered, of Zecanora atra. As I have only one 
other apothecium left, I do not care meanwhile to destroy it in order to obtain 
a more precise knowledge of the paraphyses, which appear as distinct broad. 
rods or blocks—a very unusual occurrence. 
Pertusaria multipuncta, Zurn. 
Lecidea luteola, var. conspondens, WVy/. 
Lecidea millegrana, Zayl. 
Lecidea vinicolor, Strm. .Thallus pale, yellowish or pallid, thin, shining ; 
apothecia black, sessile, flat, obscurely margined, medium ; spores 4-8, colourless, 
straight, rod-like, below attenuate, 7-12 pate, ‘04 — -06 x 0035 mm.; para- 
physes separable, apices adherent, blue-black ; hypothecium intensely red or 
wine-red, thick. The hym. with iodine first intensely blue, then wine- 
On bark. K renders the hypothecium somewhat purpurescent. The colour of 
this hypothecium is exactly that often produced by iodine on the hymenium, 
and which is called wine-red, but perhaps rubricose better indicates the colour, 
This is also a somewhat peculiar lichen. 
Lecidea glomerella, S/rm. Thallus whitish or ashy-pale, fractured into small 
plates (K yellowish). Apothecia black, sessile, width -5-1 mm.; often 
crowded or appressed and then irregular; at first mareinate, then depressed ; 
spores 8, brown, 1-septate, ellipsoid or somewhat fusiform-ellipsoid, ‘012 — O17 
x "0065 — ‘008 mim.; paraphyses distinct, slender, with brownish or almost 
colourless club-shaped apices ; hypothecium brown or blackish-brown, thick. 
Hymenium with iodine intensely blue. On bark. ‘The hypothecium is thick 
and carbonaceous, and often breaks off from the rest, leaving a thinnish 
fuscescent portion attached to the paraphyses. In this lichen the reaction by 
K on the thallus is that of Z. diseiformis, but the spores are much smaller, &e. 
Lecidea placomorpha, Sirn  Thallus pale glaucous or whitish, thin, fractured. 
into small plates (KX yellowish, finally red) ; apothecia black, sessile, small, with 
black margin ; spores 8, brown, ellipsoid, l-septate, *115 — ‘02 x ‘007 — 009 mm. ; 
paraphyses medium, fairly distinct, with brownish clavate apices; hypothecium 
Iga thin, subtended by a thick black mass. On bark. 
T have separated this from ‘LZ. d/sctformis owing to the smaller spores and 
the reactions by K on the thallus. It is true that Nylander, in his Syn. L. N. 
Caled. p. 52, gives the reactions of L. disciformis as ‘above, but in no instance, 
ya low.
