 curved at the tips. 



On the under side of leaves of Garrya ellipiica. 3145. 



Helotium furfuraceum. 



Scattered, minute, shortly stipitate or sessile, cyathiform, 

 alutaceous, furfuraceous; asci clavate; sporidia 8, oblongo- 

 elliptic, slightly curved, two nuclei, sometimes three; .015 X

 Boudiera marginata. 



Crowded, at first orbicular, then patelliform, with a ser- 

 rated margin, dull-ochraceous; asci broadly clavate, sporidia

On rabbits' dung. 2985. 



The cells of the receptacle are remarkable for their thick 

 walls, and the young sporidia for the same thing. This is 

 quite as striking a species as B. arelolata, C & Ph. 



Patellaria nigro-cyanea. 



Medium size, scattered, applanate, margined, blue within; 

 asci cylindraceo-clavate, sporidia 8, oblong, obtuse, curved, 

 one to three septa, parapliyses not seen. 



On dead stems of Audibertia stachyoides. 3097. 



Similar to Patellaria airo-vinosa B. & Br. in size and form 

 of sporidia, but differs in color and in the absence of 

 parapliyses. 



Midotis plicata. 



Cups oblique, externally granular, blackish-brown, hy- 

 menium same color, sub-plicate, asci cylindrical, spor- 

 idia 8, ovate-elliptical, slightly curved, binucleate, 005 — 007 

 X -007 mm., parapliyses 0.
