CLASSIFICATION 41? 



C. aurora. — Very thin, spreading, closely adnate, rosy, becoming 

 pale, edge indeterminate. 



Very thin, pink. Distinguished from C. typhce by the large, pip- 

 shaped spores, but scarcely by external characters. ' 



On dead leaves of Carex, etc. 



C. anthochromn. — Spreading widely, and forming thin, bright 

 rose-colour or brick-red patches that become pale, edge byssoid, paler. 



When perfectly evolved, the hymenium is waxy, and sometimes 

 cracked when dry. Usually sterile and minutely velvety under a 

 pocket lens. 



On bark, etc. 



C. molle. — -Forming roundish patches of loose texture, soft, 

 margin not byssoid ; hymenium pallid, more or less spotted with 

 red, waxy, more or less papillose or warty, cracked when dry. 



Known by the thick, soft, fleshy substance. 



C. polygonium. — Closely adnate, margin determinate, byssoid, 

 soon becoming hard ; hymenium pinkish, pruinose, usually much 

 cracked. 



Usually first appearing as small, detached tubercles, which 

 generally grow into each other, and again separating when dry, 

 thick, giving the patch a much cracked or tessellated appearance. 

 Sometimes the patch is continuous, and then more or less tuber- 

 culose or warted, edge thin, adnate, byssoid ; hymenium pruinose, 

 pinkish, lilac or dingy ochraceous. 



On bark, especially poplar, also on wood. 



C. flaveolenm. — Broadly effused, very thin, loosely attached to 

 the matrix, margin determinate ; hymenium pale primrose-yellow. 



Forming patches 2-3 in. across, suborbicular or variously lobed, 

 clear but pale primrose-yellow. 



On the trunk of a tree-fern. Perhaps an introduced species. 



C. lividiim. — Thin, spreading, closely adnate, waxy and soft, 

 variously coloured, bluish grey, dingy purple, etc., margin similar ; 

 hymenium not pruinose, shghtly viscid, cracked when dry. 



Differs from C. violaceo-lividum in the hymenium not being 

 pruinose and cracked when dry, and by the margin being coloured 

 like the hymenium. 



On dead wood, etc. 



C. atro-virens. — Irregularly spreading, very thin, blackish green, 

 the indeterminate edge tomentose, similarly coloured ; hymenium, 

 when perfectly developed, paler, glaucous, and waxy. 



On rotten wood, leaves, sticks, etc. 



3. Growing under the bark, which is lifted up and pushed off. 



C. comedens (PI. XXXIII, fig. 5). — Patches rather broadly effused, 

 inseparable from the matrix, exposed by the rupture of the bark, 

 dingy lilac, then becoming pale; hymenium even, smootli, cracked 

 when dry.
