agree, however, with the genus Reinkella; they are more or less stellate, at first 
immersed, later erumpent, and finally appressed sessile. The section of aa 
apothecium also exhibits the Opegrapha character, while Roccellographa apothecia 
show the character of the apothecia of Chiodecton. Your lichen is, therefore, a 
new species of the genus Reinkella and may perhaps be recognized as represent- 
ing a new section. But this section is weak, as the characters rest solely upon 
habit (thalli laciniae compressae, non teretes, non solidae, i. e., intus cavae.)” 
Thallus fruticose; erect or suberect laciniae scantily branching, from io 
to 20 mm., or perhaps more, long, and about 3 mm. thick (from broken condi- 
tion of specimen these measurements are approximate). Surface of younger 
and terminal laciniae smoothish, in the older or basal ones transversly tortuous 
rugose, mealy throughout. Cortex with K yellow, C red; medulla not stained 
by either, with jod giving a yellow reaction; cephaloid heaps of soredia not in- 
frequent. Cortical layer of upright (to the thallus-plane) hyaline hyphae, some- 
what clavate at tips and 4^1 thick: this layer is 20fx to 28^ high, the gonidial 
layer, immediately beneath and with definite upper border, is from three to four 
times thicker, its lower border gradually merging into the medulla, the hyphae 
of this are thinner, about 2 /jl thick, densely interwoven and those parallel to thal- 
line surface prevailing: all hyphae are indistinctly, if at all, septate; the entire 
thickness of an apical lacinia is from 120/x to 150^, the older basal laciniae beings 
considerably thicker. Epithecium subcontinuous, granulose, pale to dark 
yellow: thecium colorless, 140^ to i 6 o/jl high, lower part with dark streaks as- 
cending from the dark brown to black hypothecium: paraphyses branching, 
matted, about 2 /jl thick, containing numerous minute globules: asci clavate, 
i60jii long, 12 /I thick, membrane thick throughout, 8-spored: spores colorless, 
fusiform, 8-locular, 20n to 22n long, 4 n thick. Hym. gel. with jod. yellow, soon 
orange, K — . Spermogones not seen. 
Since Dr. Zahlbruckner most kindly has delegated the writer to partly 
describe and name this species, it is named for Mr. S. B. Parish, its discoverer, 
Oct. 19, 1913. (No. 8809 .) Type deposited with Dr. A. Zahlbruckner and in 
herbaria of the Sullivant Moss Society and Hasse.

A LIST OF HEPATIGAE COLLECTED UPON ISLE ROYALE, LAKE 
SUPERIOR 
George Hall Conklin 
During the summer of 1901, Prof. C. E. Allen and Mr. S. C. Stuntz, of the 
Botanical Department of the University of Wisconsin, visited Isle Royale, Lake 
Superior, and made an extensive collection of botanical specimens in the vicinity 
of Rock Harbor and the adjacent islands. Material was collected of all the great 
groups. Among the bryophytes were quite a number of hepatics. Through 
the kindness of Prof. Allen the writer was able to examine these specimens and 
the following determinations were made. Of especial interest was the finding 
of Riccardia multifida, Lophozia heterocolpa , Lophozia Kaurini, and Lophozia
