demum. granulato, subtus pubescenti fusco-nigro ad 
ambitum pallidiori, lobis erectiusculis lacero-dentato- 
crenatis; peltis nigro-castaneis margine lacero-fim- 
briato. — Rocks; Ragland, in Brookline, Manchester 
"woods, Medford hills, and Lexington. Also Chelms- 
ford, Mr. Russell. This appears, by the description, 
to be near Peltigera (Nephroma) Helvetica, of Spren- 
gel, l. c., a species said by him to be found in Swit- 
zerland, but not noticed in Scharer's Swiss Lichen- 
ography. 
GvnoPHona. Of the six New England species, 
enumerated in my former paper, two were inserted 
doubtfully. Further investigation has enabled me to 
speak with confidence in regard to both of these. .

Umbilicaria hirsuta, Hoffm., (cit. M. & N. ), De Cand. 
l. c., Lichen hirsutus, Ach. Pr. — Rocks, in the Notch 
_ of the White Mountains. Near G. vellea, from which 
it is well distinguished by the characters given by 
Acharius. Thallus of a whitish ash-color, somewhat 
pulverulent ; fibres of the under surface long and 
very distinct; trice hemispherical. The plant is 
much smaller than G. vellea, and less rigid. In my 
former paper, this was incorrectly considered a form 
of G. vellea, G. spadochroa is another species allied 
to G. vellea, which may occur, though I believe it 
has not yet been found in this country. E ue
