paraphyses filiform. Sporidia cylindrical-fusiform, pale yellow, 2-seriate, 

 constricted and 1-septate in the middle, each division with 4— o large 

 nuclei, and each end tipped with a small, subglobose appenda<]^e. The 

 perithecia are at length emergent or superficial wlien the epidermis dis- 

 appears. 



IlY3rEN0Cir.ETE FiMBRiATA, E. & E.— On dead Finns Murray ana, 

 Yellowstone Park, Montana, 1885. Collected by Frank Tweedy. Resup- 

 inate, suborbicular, 2—8 cm. diameter, margin umber brown, laciniately 

 divided so as to be coarsely fimbriate ; hymenium silver gray, the whole 

 forming a thick, tough, membranaceous layer which is partially separate 

 from the matiix. The hymenium is composed of a densely compacted 

 layer of erect threads, with obtuse and slightly swollen tips, giving the 

 surface a velvet-like texture. Part of these threads are hyaline and part 

 umber or chestnut brown. The former are a little longer and thus give 

 the peculiar gray tint to the hymenium which, when examined with a 

 lens, or seen with the naked eye, has the appearance of being overrun 

 with a white mould. 



ZYG0DES3IUS iNDiGOFERUS, E. & E.— -On vcry rotten Avood, West 

 Chester, Pa., Sept. 1885. Forming a thin, loose, submembranous stra- 

 tum, indigo blue, becoming greenish yellow, margin byssoid. Flocci 

 slender, branched, septate, mostly less than 3 in diameter. Spores 

 globose, smooth on short basidia (8—10 x 3 fJ-.) Approaches Thelephora. 



Dacrymyces corticioides, E. & E.— On rotten pine logs and limbs, 

 Newfield, J., Oct., 1885. Suborbicular, 2—5 mm , convex-applanate. 

 often subumbilicate-depressed in the center, pale, subvelutinous and 

 with an even surface when young, becoming pale orange and when con- 

 fluent, as it often is, more or less plicate, apparently from mutual pres- 

 sure. Basidia cylindrical, more or less dichotomously branched, 100 

 long or rfiore by about 4 thick. Spores oblong-elliptical with an oblique 

 api cuius, becoming imiseptate, 12 — 17 x 4—5 Looks much like over- 

 grown specimens of Helotium conjiuens, Schw.. or H. citrinum, Fr., when 

 fresh, and in the dry state resembles a Corticium with a narrow, white, 

 subbyssoid margin. The orange color deepens in drying. 



LOPHTOST03IA ROSEOTmcTUM, E. & E.— On dead twigs and limbs of 

 Staphylca trifoUa. Perithecia gregarious, hemispheric or subgiobose, 

 subcarbonaceous, black and roughish, imm. diameter, with a slightly 

 prominent, compressed ostiolum, covered at first by the epidermis which 

 assumes a dull, rose-colored tint, over that part of the stems occupied by 

 the fungus. Asci clavate-cylindrical, subsessile, 100 — 112 x 13 — 15 /-'- ; 

 paraphyses filiform. Sporidia cylindrical fusiform, pale yellow, 2-seriate, 

 constricted and 1-septate in the middle, each division with 4—5 large 

 nuclei, and each end tipped with a small, subgiobose appendage. The 

 perithecia are at length emergent or superficial, when the epidermis dis- 

 appears.
