cortex running through center of folds ; asci cylindrical to somewhat 

 club-shaped, gradually tapering to long stipe ; asci not constricted be- 

 tween spores, rounded at apex, 24-28 by 200-220/j. ; spores globose- 

 ellipsoid, 17-21 by 20-24jtt; paraphyses with terminal cell swollen, 

 5-8/i. tliick, about equal in length to asci.

Material under tliis number was sent to Fischer who describes it in 

 the Botanische Zeitung, 1908, pp. 157-158, and places it with G. 

 Cooperi. The specimens he received were not quite mature, and he 

 found the asci shorter (150-190^) and the paraphyses narrower (5/i,) 

 than above described. The spores in the material studied differ in 

 size from those of G. Cooperi as described by Harkness, his measure- 

 ments being 20 by 28;ti. However, this difference is no greater than 

 that found in actual measurements of Pseudhydnotrya carnea and 

 those cited by Harkness, and the discrepancy in both cases may simply 

 be due to an error in recording. Such other characters as are men- 

 tioned in his description agree with those of our species, and it seems 

 best to consider the two identical ; though since the type of G. Cooperi 

 cannot be found in the Harkness collection at Stanford University and 

 apparently also does not exist in the California Academy of Sciences 

 herbarium, there seems to be no means of definitely deciding this point.

Ascocarp reddish brown, subglobose, 4-10 cm. in diam., minutely 

 verrucose, densely tomentose, particularly in wrinkles and depres- 

 sions ; compai'atively even, with few low lobes and shallow depres- 

 sions, but surface of cortex occasionally extending far into ascocarp 

 (rarely entirely through) forming a large, clearly defined chamber 

 generally unconnected with hymenium ; walls of chamber much folded 

 and covered with tomentose cortical tissue ; gleba composed of complex 

 closely folded tissue tlirough center of which runs cortical tissue as two 

 narrow layers of pseudoparenchyma bearing intertangled septate hairs, 

 these two layers sometimes separating for short distances forming 

 small chambers; very rai'ely openings fi-om hymenium to chambers 

 present; inner walls of folds covered with hymenium, with sometimes 

 numerous short projections making surface appear thickly papillose ; 

 hymenium-lined cavity representing single hollow into which much 

 convoluted walls extend, forming numerous labyrinthine canals, later 

 occasionall}' becoming closed chambers through union of walls; larger 

 folds easily separated, but smaller more or less compactly fitted to-
