ness arc also paraphysate. Without authentic specc for comparison, 

 it can not be certainly decided that this is the veritable Hysterium 

 orhicnlare, Ehrenb., hut the locality, habitat and general characters 

 indicate that species. The perithecia are at first covered and almost 

 hidden by the whitish, orbicular scales of the leaf. 



L. Heteromelis, (Phil. & Hark.) 



Hypoderma Heteromelis, Phil. & Hark. Grev. XIII, p. 23. 



Gregarious, innate-erumpent, oblong, straight or curved, flattened 

 or slightly prominent, 400-800 JUL long. Asci clavate-cylindrical, 75- 

 80 x 5-6 //, with filiform paraphyses. Sporidia filiform. 60-65 x 1 \ JJL. 



On the under side of leaves of Heteromeles arbutifolia, Cali- 

 i'ornia (Harkness). 



The perithecia in specc. from Harkness are covered by the thin 

 epidermis, which gives them a dull appearance. The sporidia being 

 nearly as long as the asci, will place this in Lophodermium. 



L. Dracamse, Phil. & Hark. Grev. XII, p. 84. 



Scattered, elliptical or oblong-elliptical, 300-800 i long, super- 

 ficial, deciduous, glabrous; lips adherent, then open and gaping. Asci 

 clavate-cylindrical, 100x5-6 //, 8-spored, with filiform paraphyses 

 bent or hooked at the tips. Sporidia filiform, 70-85 x 1-2 p.. 



On Dracaena, California (Harkness). 



We have supplemented the original diagnosis by the examination 

 of specc. from Dr. Harkness, but can not make the paraphyses di- 

 chotomous at the tips.

 long by J-| mm. wide, with a narrow cleft and lips scarcely swollen. 

 Asci clavate, short-stipitate, 70-85 x 10-12 //, 8-spored, with filiform
