 Ascobolus depauperatus Berk. & Br. Ann. Mag. Nat. Hist. III. 15: 448. 1865. 



Apothecia scattered or gregarious, with a narrowed base which 

 is immersed in the substratum, expanding and becoming discoid, 

 scarcely exceeding 0.3 mm. in diameter; hymenium even with, 

 or slightly elevated above the surface of the substratum, at first 

 whitish with a tinge of violet, finally almost black; the excipular 

 cells angular or rounded and reaching a diameter of 5-7 /x, the 

 walls beautifully lilac, fading to brown, giving rise above to a 

 palisade of mycelia which resemble paraphyses except that they 

 are more deeply colored; asci very broad-clavate, the ends 

 strongly truncate, tapering gradually below into a stem-like 

 base, reaching a length of 65-70 ^ and a diameter of 15-17 m, 

 8-spored; spore-mass elongated, reaching a length of 30 n and a 

 diameter of 11-12 m; spores ellipsoid, the ends strongly narrowed, 

 smooth or minutely sculptured, at first hyaline, becoming deep- 

 violet, finally blackish-brown, 5 X 10-12 /x; paraphyses slender, 

 slightly enlarged above, reaching a diameter of 3-4 /x, hyaline, or 

 very faintly colored.

5. Saccobolus globuliferellus Seaver, sp. nov. 



Apothecia widely scattered, minute, scarcely visible, not 

 exceeding 0.3 mm. in diameter, milk-white; hymenium becoming 

 convex, at first white like the outside of the apothecium, finally 

 dotted over with the ends of the asci which appear black on 

 account of the dark-colored spores; asci broad-ovoid above, 

 tapering below into a stem-like base, reaching a length of 60 n 

 and a diameter of 23-25 m, 8-spored; spore-mass nearly rounded, 

 about 23 X 20 m; spores at first loosely disposed in the ascus, 

 finally collecting into the loosely united spore-mass, ellipsoid, at 

 first hyaline, later assuming a faded-blue color which finally
