Asci clavate-cylindrical. Sporidia narrowly elliptical, obtuse, con- 

 tinuous, hyaline, 8-10 x 2-2 1 . 

 On leaves, Maine. 



L. castauieola, E. & E. (in Herb.) 



Perithecia gregarious on indelinito. pale spots; mostly hypopkyl* 

 lous. erumpent. depressed-hemispherical, black, pierced above, 200- 

 250 it diam. Asci clavate. p. sp. GO x 10 <JL. aparaphysate, subs'ssil<-. 

 Sporidia biseriate above, uniseriate below, mequilaterally elliptical- 

 hyaline, continuous. 10-12x5-6 IJL. 



On decaying chestnut leaves still hanging on twigs broken oft 

 last fall. Newfield, X. J., April, 1891. 



Differs from L. eckinopMla,(Sc}i.w.).ij\ its foliicolous growth and 

 larger asci and sporidia. 



L. rubescens, E. & E. (in Herb.) 



Perithecia densely gregarious on pale spots on the upper side of 

 the leaf, minute (75-XO w), buried in the parenchyma of the leaf, but 

 visible through the raised epidermis, perforated above. The pale 

 <pots in some of the specc. finally assume a reddish hue. Asci cylin- 

 drical, about 40x6//. sessile. Sporidia uniseriate. closely packed. 

 inequilaterally elliptical, hyaline, continuous, 5-G x 3^-4 /*. 



On decaying chestnut leaves with L. c(i*tiiiii<-ol<i. from which it 



. 



differs in its smaller, more densely gregarious, epiphyllous perithecia 

 and smaller sporidia. 



L. Magnolife, (Schvv.) 



Sphceria Magnolice, Schw. Syn. N. Am. r-.< 

 Lczstadia Magnolia, Sacc. Syll. 6004, Cke. Syn. 5^30. 

 Spherrella Magnolias. Ell. Bull. Torr. Bot. Club, IX. p. 74? 

 Exsicc. Ell. N. A. F Soo. 



Perithecia aggregated in orbicular or variously shaped group- 

 finally confluent and occupying the whole lower surface of the leaf, 

 punctifbrm, covered, flattened, astomous. rising with the epidermis, at 

 length collapsing, black, but with the disk whitening out. Makes the 

 upper surface of the leaf bullate. Asci sublanceolate. Sporidia 

 biseriate, clavate-obloug. hyaline. 7 x "1\ n. 



On leaves of Magnolia ylaura. Kaign's Point arid Xewfield, X, J. 



There is no spec, of this species in Herb. Sehw.. so that we can 

 not be sun* that the specc. in X. A. F. are the N. MmjnoUd', Schw.
