100 The North American Cup-Fungi 



whitish, tomentose, the tomentum consisting of poorly developed 

 hairs; stems very variable in length, reaching 1-2 cm., irregular, 

 often clinging together in clumps, attached at the base by a 

 dense mass of white mycelium which penetrates into the sub- 

 stratum binding together the leaf-mould in which the plants 

 grow, expanding abruptly above into the apothecium; hymenium 

 concave, bright-orange, the color fading in dried specimens; 

 asci cylindric above, tapering below into a stem-like base, often 

 becoming spirally twisted, especially in dried specimens, reaching 

 a length of 300-350 ix and a diameter of 15-17 p.; spores 1-seriate, 

 obliquely arranged and with the ends overlapping, ellipsoid, at 

 first smooth, becoming sculptured, 12 X 20-23 /x; spore-sculp- 

 turing assuming the form of reticulations, the meshes of the 

 reticulations reaching a diameter of 3 ju or more, rarely 5 or 6 ^t, 

 the edges of the ridges extending 1-2 ^u beyond the periphery of 

 the spore ; paraphyses enlarged above, where they reach a diameter 

 of 6 M. filled with orange granules. 



On the ground in coniferous woods. 



Type locality: Europe. 



Distribution: Pennsylvania to Alabama and west to Wash-

Apothecia gregarious or scattered, stipitate, at first closed 

 and about the same diameter as the stem, gradually expanding 

 and becoming turbinate, the margin crenate and fringed with a 

 few delicate hairs, externally whitish or pale-orange, reaching a 

 diameter of 1 cm. ; stem rather slender and short, reaching 

 a maximum length of 5 mm., gradually expanding above into 

 the apothecium; hairs delicate, hyaline, septate, reaching a 

 length of 300 ix and a diameter of 10-12 /x; asci cylindric above, 

 tapering below into a stem-like base, reaching a length of 300- 

 350 n and a diameter of 20 /x; spores 1-seriate, obliquely arranged 

 and often with the ends overlapping, ellipsoid, containing one or 

 two (usually one) large oil-drops, at first smooth, becoming
