Daedalea confragosa Bolt. Plate XVIII. 



Pileus corky, convex, subzonate, brown with concentric zones 

 of a darker color, often concentrically furrowed and radiately 

 rugose or sulcate; wood-color within. 



Pores from subrotund and flexuous to narrowly labyrinthiform 

 and lacerate, ciereous-pruinose, then reddish-brown. 



Prostrate, hewed timber, Skokie marsh. Pepoon. On de- 

 caying, prostrate branches, Bowmanville. Harper. On stumps, 

 Glen Ellyn. 



"A handsome, finished-looking fungus, varying considerably 

 in color, roughness, etc., generally very symmetrical, centrally 

 attached and with an even margin, sometimes imbricated, two 

 or three together/' McBride, Bull. Lab. Nat. Hist. la. Ill 3 : 8. 

 Forms of this species collected at different stages of growth have 

 been described under various names. Among the synonyms are : 

 Trametes rubescens A. & S., Lenzites Crataegi Berk. ,L.Cookei Berk, 

 and L. proximo, Berk. 



CYCLOMYCES. 



Pileus coriaceous-membranaceous, velutine, fuscous or cinna- 

 mon. Lamellae concentric, becoming lacerate or polyporoid. 

 Stem central, sub-central or none. 



Cyclomyces Greenii Berk. 



Pileus orbicular, undulate, sublobate, zonate-tomentose, cin- 

 namon, marked with a few furrows near the edge. Lamellae 

 thin, acute, at length ashy. Stem central, obconic. 



On hard damp ground in a woodland road. Glen Ellyn, August 

 1901 and 1902. Only a few plants found. Pileus thin, depressed 

 then funnel-shaped, 3 to 8 cm. broad. Pores or gills thin-walled, 

 unequal in size and shape, becoming labyrinthine with age. In 

 some of our plants the pileus is sessile on the ground; in others 

 there is a short abruptly conic stem 1 to 1.5 cm. long, to which 

 the obconic pileus is joined by a narrow neck. In the largest 

 plant there is an irregular stem 4 cm. long. The context of pileus 

 and stem is wood color, corky when dry. Sometimes two or 

 three pilei are concrescent, the stems remaining separate. The 

 species, which is, rare in the United States, seems to have disap- 

 peared from our station. 



FAVOLUS. 



Pileus dimidiate, or orbicular and substipitate, annual, soft, 

 fleshy; pores reticulate-cellular, alveolate, the alveoli, formed of 

 rather densely anastomosing lamellae, radiating from the point of 

 attachment. 



Favolus alveolaris D. C. 



Pileus fleshy-tough, thin, reniform, fibrillose-scaly and tawny, 

 becoming pale and glabrous. 



Alveoli angular-elongated, whitish, the dissepiments becoming 

 thin, rigid and dentate.
