The hypothecium which is very pale-fuscous rests on a white upraised promi- 

 nence of the thallus. Paraphyses concrete, apices fuscous. Spermatia straight, 

 minute, sterigmata sub-simple. "Spores 13— 15 mm. long, 3 times as long as 

 broad.'' (Hepp.) "0.012— 16mm. long & 0.005-7 mm. broad." (T. M. Fries.) 

 " .003 in. long, by ,00125 in. broad." (Mudd.) Medulla I—. 



2. L. glohifera, (Ach.) fusco-rufous or castaneo-rufescent, squa- 

 mose, squamules reniform, imbricated, rigid, somewhat shining, 

 rimoso-inculpted, lobate, flexuose, subhorizontal, thickened at the 

 margins, concolorous or paler beneath (K — C — ) ; apothecia fus- 

 cous or black, elevated, convex and globose, immarginate, pale 

 within, solitary or aggregate ; spores 8, colourless, ellipsoid, 

 simple. 



On earth in sub-alpine calcareous localities, rare.

The hypothecium is thin and fuscescent and rests on a white globose upraised 

 prominence of the thallus. Hymenium pale-brownish, paraphyses cohcerent, 

 rufo-fuscescent at the incrassate apices ; gelatina hymenea I violet deep-blue 

 then rufo-fuscescent. " Spores 0.012—15 mm . long, 0.005 mm. broad." (Nyl.) ; 

 "9—13 mikrom long, 2— 2i longer than broad." (Hepp.); "0.012—15 mm. 

 long, 0.005—6 mm. broad." (T. M. Fr.) ; ".0015 in. long, by .00075 in. broad." 

 (Mudd.) .010— .013 mm. long, .005-006 mm. broad.

 erect, margins and under surface whitish.

Thallus K — C — ; medulla I — . The structure of the apothecium is precisely 

 similar to that of L. globifera, but the hymenium and hypothecium are more 

 darkly fuscescent, and the spores are about one-fourth larger. Paraphyses 

 cohcerent; chemical reaction nearly similar, "Spores 0.012—17 mm. long, 

 and 0.005—7 mm. broad." (T. M. Fr.) Spores .016 mm. long, .007 mm. 

 broad. 



3. L. Salweii, Borr. whitish or creamy-white, tartareous, effuse 

 or continuous, squamulose, squamules depressed, tumid or granulose, 

 bluntly lobed, oppressed, unpolished, minutely innato-granulate, (K 

 yellow C red) ; apothecia sessile, solitary or clustered, plane, lurid 

 umber-brown, pruinose, margin paler, thin, elevated, flexuose; hypo- 

 thecium pale ; spores 8, colourless, ellipsoid, simple, large, twice as 

 long as broad. 



On earth amoilg rocks, frequent. 1825.
