426 BRITISH FUN(;i 



2. Pilci overlap pi II g, growing horizontally. 



T. tcrrestris.- — Brown, then blackish, man}^ flattened, more or less 

 circular, fibrillose overlapping parts ; hymenium radiately wrinkled. 



Forming tufts 1-3 in. across. 



On the ground in pine woods. 



T. laciniata. — Brown with a tinge of purple, soft, coarsely fibrous 

 in texture, encrusting, segments overgrowing each other, margin 

 coarsely fibrillose, whitish ; hymenium rugulose and papillose. 



Known from T. terrestris by the coarsely fibrous surface, shaggy 

 margin, and papillose hymenium. 



On the ground in fir woods, running up stumps, stems of heather, 

 etc. 



T. biennis. — Greyish brown or ochraceous, sometimes with a 

 purple tinge ; pilei overlapping, tomentose, with a fringed, often 

 upturned edge ; hymenium almost even. 



Running over the ground, stones, wood, etc., and encrusting 

 e^'erything in its path. Known from T. terrestris by the even, not 

 radiato-rugulose hymenium, and from T. laciniata by the tomentose, 

 and not coarsely fibrillose pileus. 



T. mollissima. — Whitish, becoming tinged brown, encrusting, 

 very soft, either forming unbroken or continuous patches, or cut 

 up into spreading, acute-pointed segments ; hymenium almost 

 even, smooth, vinous brown. 



Sometimes forming broadly effused, irregular, encrusting patches, 

 without distinct pilei, at others erect and as much cut up as Thele- 

 phora palmata. Very soft. 



On the ground, twigs, etc., in woods. 



Cyphella 



Very minute. Cup-shaped, erect or more frequently pendulous, 

 stalkless or sessile, or with a short stem, outside downy or hairy, 

 mouth or opening of the cup not contracted. 



Tlie most frequent forms are pendulous or hanging witli the 

 opening to the hymenium downwards, and resemble in miniature 

 the head of an old-fashioned clay pipe with a very short piece of 

 the stem attached. Some .of the critical species cannot be satis- 

 factorily determined without an examination of the spores, never- 

 theless a clear idea of the genus can be gained in the field, with 

 the assistance of a good pocket lens. 



I. With a more or less distinct stem. 



C. pimii. — Whitish or very pale yellow, cup-shaped, erect or 

 pendulous, membranaceous, pubescent, margin of cup somewhat 

 torn ; stem rather slender, crooked, enlarged near the cup or pileus. 



Fasciculate ; about 2 lines high, cup about i line across. A 

 some^\•hat sliowy species of the genus. 



On dead herbaceous stems in water or in very damp places.
