from Cleveland ; on the soredia of Isidium corallinum, Ach. 
(Hardy). 1 
Spores 6 — 8, oblong, 2 — 4-locular, colourless. Possesses 
spermogonia. Th. Fries describes, without naming (Arct., 
105), a parasite on the apothecia of L. subfusca, v. lainea, 
Ach., which has yellowish 2-locular spores, but which, 
nevertheless, may prove referable to A. varians. 
2. A. punctella, Nyl. (Mudd, 252). 
On thallus of Lecidea albo-atra ; of Lecanora erysibe, Ach., 
Carroll, in my herbarium from Cork ; and Isidium coral- 
linum (Hardy) . 
Spores soleaform (2-locular), colourless. 
3. A. abrothallina, Nyl. 
I have met with no description of its characters. A. cal- 
cicola, Nyl. (Prod., 168), is apparently athalline ; but not 
parasitic on other Lichens ; a category to which belongs a 
considerable number of varieties of species that are usually 
possessed of a proper thallus. 
Genus X. — Opegrapha, Ach. 
Species 1. 0. Monspeliensis, Nyl., Prod., 153. 
On thallus of Lecanora calcarea. 
Spores oblong, brown. 
2. O. anomea, Nyl., Prod., 153. 
On Variolaria amara, which is Perlusaria communis, v. 
sorediata, Fr., according to Nylander (Prod., 98). 
Spores oblong, 4-locular, colourless. 
Genus XI. — Sphinctrina, Fr. Mudd, 255. Nyl., Syn., 
142 (whole genus parasitic). 
Species 1. — S. turbinata, Pers. (Ilepp, 326 ; Leight., Exs., 
132; Mudd, Exs., 241 ; Schaer, Exs., 6). 
Syn. Calicium, Pers. Fungi. 
C. sessile, Sm. 
Cyphelium, Hepp, 326. 
Sphceria sphincterica, Sow. Fungi, t. 286; Moug. 
and Nestler, *366. 
Lichen gelasinatus, With. 
On thallus of various Perlusarice, both saxicolous and corti- 
colous ; e. g. P. communis and P. Wulfenii (Nyl., Piod., 
33 ; Syn., 143) ; sometimes of Lecanora parella, Urceolaria 
scruposa, and other crustaeeous Lichens; of Parmelia saxatilis 
In letter of May, 1862.
