2. Ascodesmis porcina Seaver, Mycologia 8: 3. 1916. (Plate 



5, FIG. 6-9.) 



Apothecia very small, scarcely visible, scattered or thickly 

 gregarious, at first subglobose, expanding and becoming sub- 

 discoid, externally whitish or pallid, not exceeding 0.5 mm. in 

 diameter; hymenium strongly convex, becoming dark, finally 

 almost black by reason of the dark-colored spores; excipulum 

 almost wanting; asci broad-clavate to ovoid, abruptly narrowed 

 into a stem-like base, reaching a length of 75-90 m and a diameter 

 of 25-35 m; spores 2-seriate or very irregularly bunched near 

 the end of the ascus, subglobose, at first hyaline and smooth, 

 becoming pale-brown sculptured, reaching a diameter of 10-13 /x, 

 or occasionally 10-11 X 12-13 m; spore-sculpturing very variable, 

 consisting of minute rounded wart-like projections, short inter- 

 rupted ridges, or often with one conspicuous simple or branched 

 ridge extending across the visible surface of the spore ; paraphyses 

 stout, gradually enlarged at their apices, reaching a diameter of 

 about 5 /x. 



On excrement of pigs. 



Type locality: Grown in the laboratories of The New York 

 Botanical Garden on pig dung sent from Porto Rico. 



Distribution: Cultivated on pig dung from Porto Rico and 



New Jersey. 



Illustration: Mycologia 8: pi. 172, f. 6-9. 



The occurrence of this species on material collected in two 

 such widely separated localities would indicate that the species 

 is more dependent upon the substratum conditions than on 

 climate, assuming that the material collected in Porto Rico was 

 infected before it was received. 



8. CUBONIA Sacc. Syll. Fung. 8: 527. 1889. 



Apothecia sessile, convex-hemispheric, naked or clothed with 

 hairs, white or whitish; hymenium plane or convex, roughened
