getlier and soiuetiiues united ; asci cylindrical, not constricted between 

 spores, 20 by 180/x; spores smooth, l-sei-iate, ellipsoid, 14-1 S by 24/i ; 

 parapliyses a little shorter than a-sci, slightly swollen, 6/x thick.

The measurements of paraphyses and spores in this species do not 

 agree Avith those of Harkness for any of liis species of Geopora. Aside 

 from the measurements, there is nothing to exclude this species from 

 G. Cooperi as described by Harkness, but there are no characters there 

 mentioned that are particularly characteristic of this species. It 

 ditfers from G. annulata in size, comparatively even surface, very 

 definite hollow opening to exterior, unconstricted asci, and broader 

 paraphyses. It ditfers from the plants which I have referred with a 

 question to G. Cooperi, in size, regularity of surface, central liollow, 

 smaller asci, spores less globose-ellipsoid, and paraphyses with less 

 conspicuously swollen tips. 



This is the largest of the ascomycetous hypogaei reported from 

 California, being approached in size only by Piersonia hispora, which 

 sometimes reaches 8 cm. in diameter. The collector, A. A. Baroteau 

 of Alameda, California, pronounces the plants edible and delicious.

Ascocarp reddish brown and black, 2-2.5 cm. in diam., much 

 wrinkled, surface verrucose, densely tomentose particularly in 

 wrinkles, tomentose cortex extending deeply into interior; outei- cor- 

 tical tissue pseudoparenchymatous with large cells ; gleba of large, 

 loose folds containing central layer of coarse hyphal tissue continuing 

 from outer cortex, ends of folds free, enlarged; asci cylindrical, 

 strongly constricted witli annulate thickenings between spoi'es, rounded 

 at apex, 16-20 by 140-160/^; spores smooth, 1-seriate, globose-ellipsoid, 

 14-18 by 22-26/a; paraphyses not swollen at tip, 4^5|Li thick.

This species is found in the Harkness collection uutler the numbers 

 10& and probably also under 102. The type of G. Cooperi is cited 

 under the number 106 (Harkness, 18i)[), p. 270) and it is possible that 

 106 represents the type, the number 106 being a misprint. There is
