Decaying wood of ash posts below the surface of the ground. 

 Stockton, Kansas. December. E. Bartholomew. 



Effusum, stratum tenue nigrum formans; hyphae inconspicuae, 

 breves, continuae, repentes, fuscae, 3-4 ^ rrassae; sporae minutae. 

 subglobosae vel irregulares, fuscae, 4-6 p. in diam., persistenter 

 adherentes, acervulosque subglobosos, irregulares vel oblongos 

 nigricantes formantes, 20-40 // in diam. vel 20-35x40-60;/. 



Cylindrosporium conservans 



Spots numerous, amphigenous, suborbicular, sometimes conflu- 

 ent, 1-3 mm broad, green; acervuli epiphyllous, commonly 1-6 on 

 a spot; spores filiform, curved, 40-75// long, 3-4 fj. broad, oozing

Leaves of Scouler's willow, Salix scouleriana Barr 

 Rolling Bay, Washington. August. E. Bartholomew, ^^^^^'^/^j/^'^^ 



The spots are surrounded by the yellow or greenish yellow tissue 

 of the leaves, the fungus apparently preventing the discoloration 

 of the tissues in proximity to it. This character is suggestive of the 

 specific name. The center of the spots appears paler on the upper 

 surface because of the spore masses. 



Maculae numerosae, amphigenae, suWrbiculares, aliciuando con- 

 fluentes, 1-3 mm latae, virides ; acervuli epiphylli, vulgo 1-6 in 

 quavis macula; sporae filiformes, 40-75x3-4//, curvatae, exun- 

 dantes et massas aut claviculas persistentes albidas melleasve for- 

 mantes. 



Diaporthe callicarpae 



Stroma effused, thin, blackening the surface of the wood ; peri- 

 thecia immersed in the wood, commonly 2-6, depressed-globose, 

 .3-.5 mm broad, black, ostiola minute, barely emerging from the 

 blackened surface of the wood and rupturing the epidermis ; asci 

 very slender, narrowed at each end, 60-80 .'j- long, 6-8 !'■ broad, 

 spores distichous, 4-nucleate, 12-15// ^o"?' 3~4 '^- broad.

 perceptible.
