"Est species vicina L. urceolata, Acli., et differens przecipue apothe- 
cus planis." This is unlike any other British species. L. urceolata 
is American. 
Agyrium rufum (Pers.), Fr.— On old stems of Calluna vulgaris, L. 
foot of Croghane Mount, Killarney (Wright and Carroll), April, 1867.

roll). 
Arthonia iUcinella, Nyl. Flora, 1867, p. 179.— On young trees, Turk 
Mount (Carroll). Near A. ilicina, Tayl., but the spores are much 
smaller, and the hymeneal gelatine " iodo vinoso rubescente " (in A. ili- 
cina cserulescente). Apparently rare at Killarney. 
Melaspilea amoln, Nyl. Flora, 1867, p. 178.— Thallus macula albida 
mdeterminata indicatus vol vix ullus distinctus; npothccia nigra, innata, 
rotunda ta vel rotundo-difformia (latit. 0-5 millim., vel parum amplius), 
ffiargine proprio tenui inaequali ; sporse 4-8-nse, incolores, 1-septata 1 , 
medio constrictae (longit. 0-016-22 millim., crassit. 0-007-0-010 
muhm.) ; paraphyses vix ullae ; thccae confertse ; epithecium fuscescens 
y el fusco-luteum ; hypothecium tenuiter ct leviter vage obscuratum. 
Iodo gelatina hymeneum vel thecae dilute caTulescunt (qui color dein 
evanescit).— On oak, Turk Mount (Carroll). " A M. afihonioide 
ifyrmgelii, Ach.) mox paranhysibus deficientibus diatat." 
Verrucaria mcrcbporoides, Nyl. — Plentiful under a shaded ledge of 
rocks at Kilkee (Carroll). 
V. acrotella, Ach. — V. mntahilh, Borr.— Carrig Mount, Kerry

F. epyaoufa, Nyl. Flora, 1867, p. 327.— On the ground cliffs of 
Moher, co. Clare (Carroll).— "Similis epigeeee, scd minor et sporis 
3 -septatis. Vix sumi possit pro statu terrestri V. chlorotica, nam 
°ostant jam apothecia immersa et profunda, perithecio alio." 
f. lucens, Tayl.— On basalt, Croghane (Carroll). A fine species, 
ff) th very prominent apothecia, large fusiform 7-septate spores, and 
remarkably stout paraphyses. 
V- capnodes, Nyl. = V. rhjponta, Borr., Leight. (non Ach.).— Grow- 
m S in small patches on thallus of Graphis sophislica, Nyl., in Castlc- 
bemard Park, Bandon. Distinguished from V. rltgponta, Ach., by its 
entire perithelium and uniseptate spores. 
v -<jlabratn, Ach.~ V. achroopora, Nyl. Flora, 1867, p. 179, et V.gla- 
'"•"tofo.Nyl. Flora, 1867, p. 330.— Killarney (Carroll). These two forms,
