308 NEW BRITISH CRYPTOGAMIA. 
or lighter leaden-grey ; apothecia few and scattered, sessile on small 
elevations of the crust, minute, the disk concave or plane, margin 
thickish, black, shining ; sporidia oblong-oval, bilocular. Of this plant 
Mr. Mudd, who examined a fragment, says, ‘‘ The internal structure 
of the apothecia is similar to those of Lecania erysibe, y. aipospila, 
Borr.; but the external aspect of the whole plant hardly corresponds 
with that of aipospila.” Till better examples are procured I place it 
next to B. chalybeia, Borr., which it closely resembles externally. 
Loc. In the cavities of red sandstone rocks beaten by the sea at 
Greenheugh Point, Berwickshire; only a few specimens obtained, 
and those probably in a degenerate state. (James Hardy, in the Pro- 
ceedings of the Berwickshire Naturalists’ Club, 1863, p. 410.) i 
3. EPHEBE BYSSOIDES, Carrington. Thallus creeping over Hepatice, 
byssoid; filaments as thick as horsehair ; tender, olive-blue, polished, 
terete, flexuose, fasciculately branched, the apices obtuse, bifid ; apo- 
thecia wart-liké, smooth, immarginate, very minute, flesh-coloured ; 
spores numerous and exceedingly small, invisible without a lens, oval ©). 
In habit and structure this species approaches Ephebe pubescens, Fries, 
which is, however, more rigid, and the thallus is of a sooty- oe 
colour, brittle, with subulate points, and bearing black warts; besides 
the gonidia are arranged groups of four or more cells, while in Z. dys 
soides they are in moniliform rows. 
oc. In shallow depressed patches, an inch or more in extent, on 
Frullania Tamarisci, var. microphylla, Gott., at Glena, Killarney. .— 
This is probably the same plant as that described by Dr. bu 
Moore as Leptogium Moorii, Hepp. (L. anomalum, Moore, ms.), Wit 
the following characters;— Thallus coriaceo-gelatinous, filamentose, 
fruticulose, terete-compressed, rugose, dichotomously branched ; CyN 
obtuse; gonidiac granules scarcely coherent ; colour dark olive-gree 
apothecia unknown. ‘The specimens were obtained from Cromaglow®, 
Kerry, and Glengariff, Cork. Aer 
4. LECIDEA SCAPANARIA, Carrington; Dactylospora scapin 
Mudd. (in Sched,). Thallus none ; apothecia minute, sparingly e 
tered, eoaretate when young, explanate when mature or ol i arr, à 
plane, dull reddish-black, surrounded by an elevated, somewhat tum 
margin of the same colour; hypothecium thin, dark yellowish-brow™ 
grumous; paraphyses short, somewhat lax, pale, their apices ©" 
brown; asci broadly clavate, 6-8-spored ; spores obtusely fusiform»
