4. Verrucaria analeptoides, Ny]. 
Extus subsimilis analepte, sed revera forte sola varietas V. ante- 
cellentis Nyl. (in ‘Flora’ 1866, p. 86); sporis (1-septatis) 
longit. 0:036-0:050 millim., crassit. 0°009-0:010 millim. 
Variant spore septis (spuriis) 83-5. Paraphyses sepe lax. 
Hibernia, Killarney ; legit Carroll, 1866. 
5. Verrucaria desistens, Nyl. 
Thallus vix ullus proprius; apothecia perithecio integro minuto 
(diam. 0-1 millim.), parte dimidia supera convexa prominula ; 
spore 8, incolores, fusiformes, 3—5-septate, rectz, longit. 
0:011-0°016 millim., crassit. 0°003-0°004 millim.; para- 
physes null. Iodo gelatina hymenea vinose rubens. 
In Hibernia, Killarney, ad corticem JTlicis legit Carroll 
(1866). | 
Prope V. albissimam locum habeat, sed recedit variis notis a 
stirpe V. epidermidis. 
| 6. Lecanora Hutchinsie, Ny). 
Thallus pallido-cinerascens vel flavido-cinerascens tenuis, ri- 
mosus vel rimuloso-diffractus ; apothecia rufo-testacea (latit. 
0-5 millim.), convexa, biatorina; spore 8, incolores, fusi- 
formes, 1-septate, longit. 0°010-0°012 millim., crassit. 
0:0025-0:0035 millim., paraphyses crassulz (crass. 0°0025— 
0:0035 millim.), nonnihil articulate, apice incrassato, inco- 
lore; hypothecium incolor. Iodo gelatina hymenea ceru- 
lescens (cum thecis, que apice intensius tinguntur). 
Ad saxa in Hibernia (Miss Hutchins ex hb. Carroll.). 
Facies Lecidee cujusdam propinque vernali, sed theoretice 
Lecanora, nam spermogonia ut in stirpe Lecanore subfusce, ubi 
accedit ad erysibem. Spore tenues et paraphyses crassz speci- 
men distinguunt. Spermatia arcuata, longit. 0-020 millim., 
crassit. vix. 0°001 millim. 
7. Lecidea aphana, Ny]. 
Thallus griseus, tenuis, subverrucose vel subgranulose inzequalis, 
indeterminatus ; apothecia nigra, parvula (latit. 0°2—0°4 mil-

incolores, ellipsoidee vel oblonge, simplices, longit. 0°008— 
0:011 millim., crass. 0°0035—0:0045 millim., thalamium vage 
violaceo-fuscescens (epithecio vix obscuriore) ; paraphyses 
non discretz ; hypothecium incolor (vel interdum vage infra 
tenuiter violaceo-fuscescens). Jodo gelatina hymenea ceru-
