Spores oblong or blunt-fusiform, at first colorless, but brown with age, 

 three-septate, the regular cells enclosing quadrate nucleoli, 33 x 1 2-18^1, hypo- 

 thecium grayish, paraphyses distinct, discrete, the tips reddish, with the upper 

 portion of the hymenium reddish downward. 



Interesting as affording internal characters in complete accordance with 

 those of the European plant. The thallus is comparable with that of L. tur- 

 Jacea, and wholly irreconcilable with that of the Californian plant described in 

 Tuckerman's Synopsis, p. 210. 



BiATORA ciNNABARiNA (Sommerf.) Fr. Lich. Eur. Ref., p. 266. 



On bark of Tsuga. Mt. Ellinor, Wash., alt. 4,000 ft., No. 2107. 

 Spores oblong, 10-12 x 3-4^. 



Reported from British Columbia and Oregon, but almost unknown to our 

 American collectors. 

 Biatora myriocarpella, sp. nov. 



No visible thallus, but the fibres of the substratum afford hyphema, and 

 nestling among the filaments, algae. Apothecia minute (about 0.25 mm.), 

 very numerous, sessile, from flattish to strongly convex, immarginate, the disk 

 from dark brown to more commonly blackish, scabrous and epruinose. Spores 

 eight in each ascus, from ellipsoid to oblong, predominantly simple, but some- 

 times thinly septate, colorless, 8 x 4ju, hymenium and hypothecium hyaline, 

 paraphyses gelatinous, the tips dark or purple, asci ventricose-clavate. 



On cedar fence posts. Gate, Wash., No. 1987. 



Comparable with B. turgidula, but the hypothecium colorless, the apothecia 

 smaller and more abundant, and the spores discrepant. 



Type specimen in herb. Merrill; co-type in Mr. Foster's collection. 

 Biatora {Biatorina) pilularis (Koerb.) comb. nov. 



Thallus from white to sordid-whitish, thin, finely granulose, effuse, K — , 

 C — . Apothetia small (about 0.3 mm.) adnate, soon convex or even sub-globose, 

 yellowish-flesh or brick-red colored, without visible margin. Spores eight in 

 each ascus, ellipsoid, colorless, one-septate, 7-10 x 3.5-4/i, hymenium and 

 hypothecium hyaline, paraphyses distinct, compacted, wholly without color at 

 the tips, asci ventricose-clavate, with the apical wall thick, hymenial gel. with 

 I. -}- blue above, wine-red below. 



On bark of aspen. Republic, Wash. 



Spores smaller than in the recorded measurements for the European speci- 

 mens, and more like those of B. cyrtella. New to America. 

 Lecidea (Buellia) papillata Fr. Lich. Eur. Ref., p. 336. 



On thin earth over rocks. Republic, Wash., No. 2299. 



Spores oblong-ellipsoid, ellipsoid or blunt-fusiform, one-septate commonly, 

 three-septate rarely, 30-40 x 11-15M, hymenium colorless, hypothecium brown, 

 paraphyses distinct, lax, tips brown, the asci ventricose with the apical wall 

 very thick. 



Remarkable for its excessively large spores. Previously recorded from 

 Washington.
