RIDDLE: THE LICHENS OF BERMUDA 159 
regarded as certain, but the thalline characters agree exactly with 
those of the species cited. As this species is entirely unknown in 
America, the interesting possibility suggests itself of its having 
been introduced into Bermuda from England, where it is common 
in just such habitats as the one given. 
77- BUELLIA MyRIOCARPA (DC.) Mudd. 
On bark of Melia, Tucker’s Town, E. G. B. 867 in part; with- 
out definite station, W. G. Farlow. 
78. BUELLIA PARASEMA (Ach.) Th. Fr. 
On pine-rail fence, Paynter’s Vale, Brown & Britton 991; on 
Juniperus, St. David’s Island, Brown, Britton & Bisset 2078. 
: The Bermuda material of this species varies considerably 
from the species as known in the northeastern United States. The 
thallus is either more distinctly areolate, or, in other specimens, 
almost absent, the disk of the apothecia is very flat, and the spores 
of the minimum size for the species. Yet it scarcely seems worth 
while giving a varietal name in the case of such a polymorphic 
species. 
79. Rinopina insperata (Nyl.) Zahlbr.; Engler & Prantl, Nat. 
Pflanzenfam. 1!*: 232. 1907. 
Without definite station, Challenger Expedition. 
This was published originally as Lecanora insperata Nyl. Act. 
Soc. Sci. Fenn. 7: 443. 1863. Then it was changed to Lecidea 
Nyl.; Crombie, Jour. Linn. Soc: Bot. 16: 215. 1877- Hue, in 
his Lichenes Exotici (Nouv. Arch. Mus. d’Hist. Nat. Paris il. 
3: 139. 1891), places it under ‘‘Stirps Lecideae (Buelliae) 
myriocarpae.” An examination of an apothecium from an 
original specimen in Lindig’s Lich. Nov. Gran. No. 2616 shows 
beyond doubt that Zahlbruckner’s disposition of the species 1s 
Correct, in spite of the thalline exciple having disappeared. 
80. BLASTENIA FLORIDANA (Tuck.) Zahlbr. 
On tamarisk, Biological Station, E. G. B. 36, and on Coccolobis, 
north of Hamilton, E. G. B. 66.
