X. rlKstica, Hepp., var. hyperloreay ^y\, = ^sjjicilia atJiroocaypa^ 
Mudd, Man. p. 164. — On liigli mountains, frequent, 
L, atJiroocarpa^ Dub. ; Nyl. Licli. Par. 39, 40 = Lecania ccerulescens, 
Mudd, Man. p. 140,— Walls, Ayton and Cle\^eland (Mudd in Herb. 
Carroll). 
Z, albariella, Nyl. in litt. — On chalk, Glenarm (Jones). 
Fertnsaria nolens, NyL Flora, 1864, p. 489. — On basalt, near Glen- 
arm (Jones). Asci 8-spored, Nylander observes tliat this species 
might be readily mistaken, unless microscopically and chemically ex- 
amined, for a form of Lecanora c'merea, and that it seems to form a 
connecting link between Tertnsaria and Lecanora. 
P, glonierata, Scha^r., Mudd,*Man. p. 277. — On north side of Ben 
Lawers (July 1864, Carroll). 
Thelotrema sMile, Tuck. — -'' Thallus macula lactea subnitidiuscula 
iudicatus; apothecia incoloria (alba), enimpentia, sat parva (latit. 0*4 
mil1im.),margine thallodio parum proraihulo, proprio saepe albo-pulveni- 
lento; sporge S-nss, incolores, oblongae, 10-13-loculares, longit. O'OIO- 
56, crassit. 0"009-0'010 millim. (lodo-casrulescentes). Parum (etpr^- 
sertim sporis majoribus) difFert a Thelotremate hicinctida^ Nyl." — On 
a young beech by Lough Inchiquin, Kerry, Aug. 1864 (Carroll), very 
rare. This species belongs to a small group of American Lichens which 
extend to western Europe, and especially to the south-west of Ireland, 
among which are Sticta dam^cornis, S. inlricata, Lecidia mnlabilis 
(which I also have from Portugal), and Grapliis Rniziana. 
Lecidea Flotovii, Korb. ; Gyaleda truucigena^ Mudd, Man. p. 167 
(pr. p.), Exs. 140 ! — Curraghmore, Watei-ford (Jones), Castleconnel, 
Limerick (Carroll). Very near Z. truncigenay Acb., but differs in its 
ovate spores, 
L. rubiformh, Whlnb. ; i. glohifera^ Ach,, var. rubiformis, Nyl. 
Lich, Scand. p. 193. — Summit of Ben Lawers, rare (Jones, afterwards 
Carroll). 
Z. rjikobola^ Nyl. Flora, 1865, p. 4.- — Summit of Ben Lawers, rare 
(Jones). Very near L. globifera, and chiefly distinguished by the long 
rootlet sent down from the centre of each scale of the thallus. 
L./uUginosa, Tayl. Fl. Hib. part 3, p. 131; Mudd, Man. p. 208.
