pitosae, flexuosae vel irregulares, 30-40 // longae, vulgo asep- 

 tatae, leviter coloratae; sporae oblongae vel ad apicem attenuatae, 

 2-4-septatae, 35-60 X 3-4^,,. 



Cladosporium paeoniae Pass. 



Living leaves of paeonia. Batavia. August. D. B. VanBuren. 

 Collected by Alice G. Fisher. The fungus forms large brown spots 

 on the leaves. It sometimes occupies the entire leaf and kills it

Clitocybe biformis n. sp. 



Plate VI, figures 9-15 



Pileus fleshy, thin, firm, broadly convex or nearly plane, be- 

 coming centrally depressed, subumbilicate or broadly infundibuli- 

 form, glabrous, even or slightly striate on the margin, pale buff, 

 sometimes more brightly colored in the center, flesh white or 

 whitish, margin at first involute ; lamellae thin, close, narrow, de- 

 current, whitish, becoming pallid or subcinnamon with age or in 

 drying; stem equal or nearly so, firm, solid or stuffed, often curved, 

 sometimes eccentric, tomentose at the base, colored like the pileus ; 

 spores subglobose or broadly elliptic, 5-6 /j- long, 4-5 p. broad. 



Pileus 2.5-7.5 ^^ broad; stem 2.5-3.5 cm long, 4-8 mm thick. 



In mixed woods. Growing in arcs of circles. North Elba. 

 Essex CO. September. 



When young the pileus is convex, when old it is centrally de- 

 pressed or sometimes broadly infundibuliform. This change of 

 shape has suggested the specific name. The change in the color 

 of the lamellae is more remarkable. The species is closely allied 

 to 'Clitocybe g i 1 v a (Pers.) Fr. from which it may be 

 separated by the whitish color of the flesh and the peculiar change 

 of color in the lamellae. This passes from whitish to fawn color 

 or pale cinnamon. Its habit of growing in circles is also peculiar. 

 The mycelium binds together a mass of dirt and decaying vege- 

 table matter. These adhere closely to the base of the stem when 

 the mushroom is pulled from its place of growth, and make the 

 stem appear as if bulbous.
