spores. The subiculum also is tomentose, not crustaceous. The 



perithecia are sometimes entirely black and almost wholly glabrous^ 



Perithecia gregaria, globosa, tomento effuso atro insidentia, 

 ad apicem subglabra rufo-brunneaque vel grisea, aliquando omnino 

 atra, ostiolis obscure laceratis ; asci clavati subcylindraceive, 



60-100 /i longi, 10-12// lati ; sporae confertae subdistichaeve, ob- 

 longae, subfusiformes, rectae vel subcurvatae, uniseptatae, liyalinae, 

 in maturitate flavescentes, 16-20/i longae, 6-8// latae ; cellula 

 quaque 1-2-septata. 



Botrytis uredinicola 



Tufts T-2 mm. broad, hypophyllous, soft, snowy white ; hyphae 

 rather short, sparingly branched, septate, branches very, short ;" 

 spores globose, hyaline, 8-10 // in diameter.

tall smooth panic grass, Paniaim virgatian L. Stockton, Kansas.

Caespites 1-2 mm. lati, hypophylli, molles, nlvei ; hyphae

 globosae, hyalinae, 8-10// latae. 



Gyroceras divergens

Spots on the upper surface of the leaf grayish with a faint 

 purplish tinge, on the lower surface purplish brown, more or less 

 confluent ; hyphae hypophyllous, the sterile creeping, branched, 

 often short, hyaline or pallid, the fertile suberect, multiseptate, 

 variable in lenerth and diameter, 20-80 /i X 6-10 /i, forming brown

inhabitant of Celtis aitstralis, in the color of the spots and in its 

 chains of spores, which are shorter, broader, and erect, not in- 

 curved or involute at the apex, and in sometimes having a few of 

 the articulations longitudinally divided. In this character the 

 species diverges from the typical character of the genus. The 

 number of septa in a spore chain may vary from 3 to 15, but in G. 

 Celtidis they may exceed 20. In our fungus the apical cells or 

 spores are sometimes broader than the basal ones, thereby giving
