F. isidioides, Borr. — Dermatocarpon isidioides, Mudd; Man. p. 270. 
—Thece normally 8-spored ; spores when young 7-septate acute, in 
age obtuse muriform dark-brown ; inch 0:015 long, by 0:006 broad ; 
paraphyses conglutinate, hymeneal gelatine unaffected by iodine, or 
only tinged of a pale straw-colour.— On slate rocks, Glengariff 
(Hutchins in Herb. Lindsay, commun. by Carroll). On examining 
good specimens I find that this curious plant has no affinity, except in 
a very close outward resemblance, with V. clopima, to which I had 
incorrectly referred it in the first part of these * Contributions." 
V. theleodes, Smmrf.; var. inundata, Nyl. in litt.—Moist rocks, 
Ballaghbeama Gap, Kerry (Carroll) ; and in a stream at Cromaglown, 
Killarney (Jones). 
V. nigritella, Nyl. Flora, July, 1865, p. 357.—Thallus doubtful; 
apothecia, whieh are prominent, black; occur between the scales of: 
V. tephroides, near the summit of pee (Carroll). Spores dark- 
brown, oblong ellipsoid, variously divided (very like those of Urceolaria 
scruposa) much smaller than the spores of V. nigrata. 
V. integra, Nyl. Pyrenoc. p. 31.— On rocks, near Cork (Carroll). 
V. prominula, Nyl.—In a dark cave by the sea, at Kilkee, co. Clare 
(Carroll). 
V. superposita, Nyl. Flora, July, 1865, p. 357.— Parasitic on thallus 
of V. theleodes, Smmrf.—Near the summit of Lawers (Carroll and 
Jones) A curious little plant, not unlike V. Porreri in miniature. 
Spores 1-septate. 
V. endococcoidea, Nyl. Flora, July, 1865, p. 356.—Parasitic on 
thallus of Lecidea excentrica, near the summit of Lawers (Carroll). 
What is apparently the same plant occurs at Killarney, and near Dublin, 
also on thallus of Z. excentrica (Jones). ‘Sporis iodo czrulescen- 
tibus. 
V. dubiella, Nyl. Flora, July, 1865, p. 356.—0On moss, north side 
of Ben Lawers, July, 1864 (Carroll). *'Species bene distincta, forte 
parasita ; sporis sat parvis 3-septatis," Nyl. L c. 
V. epidermidis, Ach. ; var. allogena.— V. allogena, Nyl. Flora, July, 
1865, p. 357.— Near the summit of Lawers, growing on thallus of 
Lecidea excentrica (Carroll). 
F. epidermidis, Ach. ; var. platypyrenia.=V. platypyrenia, Nyl. Flora, 
July, 1865, p. 358.—On Ivy, at Ballyedmond, co. Cork, and at Old 
Dromore, Kerry (Carroll). Spores 3—5-septate.
