mined a specimen from Minneapolis, on sandstone, as L. goniophila, and a 

 fragment in my herbarium from what is taken to be the locaUty mentioned, 

 labeled L. goniophila and communicated by Dr. Fink, undoubtedly belongs with 

 the species. 



Lecidea {Buellia) verruculosa (Borr.) Schaer. Enum. p. 114. (1850). 



Thallus small, orbicular or irregular, verruculose-areolate, the areola more 

 or less scattered toward the circumference, yellowish-green varying to fuscous, 

 K — , C + orange-red. Apothecia immersed in the thalline verrucae, small, 

 disk plane, black. Spores 8, ovoid or ellipsoid, bilocular, brown, 15-21 x 8-1 1 

 hypothecium brown, fuscescent or sometimes pale, paraphyses distinct, co- 

 herent, brown at the tips, hymenial gel. with I -f deep blue. 



On rocks in walls and in rock heaps, Rockland. 



Apothecia, one in each thalline verruca, and with a spurious thalline border. 

 Reported from Newfoundland, but I know of no record for the United 

 States. Issued in Lichenes Exsiccati Merrill No. 250. 



Lecidea {Buellia) myriocarpa var. punctiformis (Hoffm.) Lamy Mont-Dore, 

 p. 139. (1880.) 



On old bricks. Warren, and lignicoline in Thomaston. 



Thallus on bricks a filmy sub-dendritic stain. Apothecia very minute. 

 Spores 8, agglutinated, bilocular, ellipsoid, not constricted at the septum, 10- 

 14 X 6-7.5 hypothecium brownish, asci ventricose, paraphyses distinct, thick- 

 ened, tips clavate and brown. 



Not previously reported from the United States under this combination, 

 but recorded from Newfoundland as Buellia punctiformis. Tuckerman made 

 no attempt to differentiate the various forms of the species. 



Lecidea {Buellia) turgescens Nyl. in Tuck. Gen. p. 187, and Syn. Pt. 11^ 

 p. 98. (1888.) 



On old clapboards, Rockport. 



This is the common condition of the species from a lignicoline substratum. 

 A plant found on white pine in Brunswick, has a conspicuously plicate-verrucose 

 brown thallus and is the finest example of the species yet examined. The thallus 

 is effuse, incrassated centrally, but diminishing in thickness to the filmy-oliva- 

 ceous border. The apothecia appear as if immersed, due to the turgid thallus.

Buellia Miill. ' 



Parasitic, apothecia small, black, opaque, epruinose, with a persistent and 

 rather thin margin. Spores 8, bilocular, from pale to deep brown, 12-13 x 

 3.5-5 n, hypothecium blackish-brown, asci ventricose-clavate, paraphyses dis- 

 tinct but gelatinous, tips clavate and faintly colored. 



On thallus of Baeomyces rufus, No. Haven. 



Answering better to Miiller's description than to any found for L. scah- 

 rosa. The spores in our plant appear not to be constricted at the septum, and 

 are slightly longer and narrower than those of L. scabrosa. The paraphyses 

 agree perfectly with Miiller's figure. In any broad view the plant is synony- 

 mous with L. scabrosa.
