168 CYCLOCARPINEE [GYALECTA 
Castle, Herefordshire; Craig-y-Rhiw, near Oswestry, Shropshire ; 
near Rievaulx, Bilsdale and Greta Bridge, Yorkshire; Craig Tulloch, 
Blair Athole, Perthshire. 
‘‘Phialopsis livida Mudd Man. p. 166 (1861).—Thallus effuse, 
thinnish, subtartareous, granulose-verrucose, becoming somewhat 
leprose, white. Apothecia small, not numerous, scattered, sessile, 
the disc dull- or bluish-black, slightly concave then plane, the 
margin thickish, smooth, polished, white ; hypothecium dark-red, 
grumous ; spores 8 in the ascus, ellipsoid-oblong, irregularly 
4-celled.” Specimen not seen. 
Mudd has stated that “‘ this species somewhat resembles Lecanora 
(Aspicilia) verrucosa in its mode of expansion and outward appear- 
ance. It may be known by the colour of its hypothecium, stout 
paraphyses and by the internal organization of its spores.” In the 
absence of specimens it is advisable to leave it where Mudd placed it— 
next to ‘‘ Phialopsis rubra’’—until the plant has been again collected. 
Hab. On the trunks of old trees, Killarney, Kerry. 
LECIDEA Ach. (Part 2, p. 10.) 
Species overlooked, or issued since the publication of Part 2. 
*L. prostratula Stirt. in Scott. Nat. v. p. 218 (1880).— 
‘Thallus pale or pale-grey, thin, squamulose, the squamules 
:adpressed, plane, scattered or contiguous with occasionally crenu- 
late margins, on a black hypothallus (K —, CaCl + reddish). 
Apothecia black, sessile, about -6 mm. wide, plane, marginate, 
becoming convex and almost immarginate ; hypothecium brownish- 
black ; paraphyses somewhat irregular, medium-sized, distinct, 
conglutinate at the black clavate apices ; spores colourless, ellip- 
soid, simple, 9-12 » long, 5-6 » thick ; hymenial gelatine slightly 
bluish then wine-red with iodine. 
From the squamulose thallus, the species should be placed near 
to L. Friesii (Part 2, p. 14). 
Hab. On rocks, Craig Var, Kinloch Rannoch, Perthshire. 
L. hypocyanea Stirt. 1. c.-—Thallus pallid or pallid cinereous, 
rugulose, squamulose-congested. Apothecia brown or brownish- 
black, small ("2-4 mm. wide), convex, immarginate, aggregate 
or congested (12-30 glomerulate) ; hypothecium red, the sub- 
hymenial stratum thickish, bluish or intensely blue ; paraphyses 
not discrete, conglutinate at the apices, not clavate nor inspersed ; 
spores 8 in saccate asci, ellipsoid, simple, 9-12 » long, 6—7 » thick. 
Possibly akin to L. endocyanea Stirt. (Part 2, p. 17). Stirton 
states that the blue colour is lacking here and there, and that nitric 
acid applied gives at first a violaceous tint which ultimately vanishes. 
Hab. On soil at the foot of Ben Lawers, Perthshire. 
™ Stirton’s specimens have recently been sent for examination to 
the British Museum, where a set will be preserved. A revision of 
the species will be published in due course.
