20 PLANTS BAKERIAN^. 



MYCOSPH^ERELLA sp. On dead stems of Senecio near Pa- 

 gosa Peak, 10,000 feet, 29 Aug. ; n. 40. 



PLEOSPORACE.E. 



LEPTOSPH.ERIA DOLIOLUM (Pers.) De Not. Schem. Sfer. 61. 

 On dead stems of Heracleum, near Pagosa Peak, 10,000 

 feet, 29 Aug.; n. 32. 



LEPTOSPH^RIA LUPINICOLA, n. sp. Perithecia thickly scat- 

 tered or gregarious, buried but becoming exposed by the 

 shredding of the epidermis, black, somewhat roughened, not 

 collapsing, ostioles strongly papillate, 200-250/i; asci sub- 

 cylindric, thin walled, about 80x8^; paraphyses threadlike; 

 ascospores subdistichous, cylindric, curved, light olivaceous, 

 3-septate, cells uniform, not constricted, 25-30x4/4. 



On dead lupine stems, Hermosa, 4 April ; n. 82. This 

 seems to be sufficiently distinct from any of the many species 

 attributed to papilionaceous hosts. 



LEPTOSPH^RIA TYPH^E Karst. (?) Myc. Fenn. ii. 99. 



On dead stems of Typha, at Hermosa, 30 March ; n. 33. 



This differs materially from all other specimens of Lepto- 

 sphseria found on Typha in this country in the decidedly 

 smaller spores and narrower asci. Our specimens have the 

 asci about 60xl2/x and the spores only 20x5/-t, while in 

 specimens of L. typharum (Desm.) Karst. the asci are 

 60-80x20/4, and the spores 25-30x7-8/4. Our measurements 

 of perithecia asci and spores agree closely with those pub- 

 lished for L. Typhse, but in our specimens the perithecia are 

 often densely cespitose in clusters of 6 or 8 to 20 forming 

 double or single lines and not "scattered" as described for 

 the European specimens. 



LEPTOSPHAERIA VERATRI, n. sp. Perithecia scattered, 

 buried except the strongly papillate ostioles, J-Jmm., of
