RIDDLE: THE LICHENS oF BERMUDA 153 
comb. nov., but differing in the thallus being entirely made up of 
sulphury granules, which under the microscope are seen to be 
glomerules of gonidia with a loose mixture of hyphae. The regular, 
marginate apothecia, resembling those of Microphiale lutea, also 
distinguish this species from B. floridana. 
42. Bilimbia sphaeroides var. vacillans (Nyl.) Riddle, comb. nov. 
Lecidea sphaeroides var. vacillans N yl. Lich. Scand. 204. 1861. 
Without definite station, Brown, Britton & Seaver, 1270. 
43. BAcIDIA FUSCORUBELLA (Hoffm.) Th. Fr. 
On Rhizophora, Fairy Land, E. G. B. 194 in part; without 
definite station, W. G. Farlow. 
Agrees well with Wright’s Lich. Cub. No. 220, in the Tuckerman 
Herbarium under the synonym Biatora rubella var. spadicea (Ach.) 
uck. 
44. CLADONIA FIMBRIATA var. BORBONICA (Del.) Wainio. 
On a roadside banking, Harrington House, Brown & Britton 
§52. Tropical material of the fimbriata-pityrea group offers an 
almost hopeless problem, but this specimen agrees well with 
Wright’s Lich. Cub. No. 31, which is cited by Wainio under his 
account of this variety. 
45. CLADONIA FIMBRIATA var. NEMOXYNA (Ach.) Coem. 
According to Wainio, the specimen called ‘Cl. fibula Hofim.” 
in Crombie’s Report belongs here. The specimen listed in the 
Same report as ‘Cl. acuminata var. hebescens Nyl.” is said by 
Wainio to be related to Cl. fimbriata, but not in condition for 
determination. 
46. CLADONIA FIMBRIATA var. SIMPLEX (Weis.) Flot. 
On a stone-wall near St. Mark’s Church, Brown & Britton 496; 
E.G. B. 1861. 
The squamules of the primary thallus are more compact than 
In northern material, but there seems to be nothing else to dis- 
tinguish this.
