290 Rev. M. J. Berkeley and Rev. M. A. Curtis on new 



to characterize it very imperfectly, but it is too marked to be 

 omitted entirely. 



74. A. (Leptonia) assularum, B. & C. Pileo e campanulato 

 explanato, umbonato glabro virgato albido ; stipite fuligineo ; 

 lamellis ex albo carneis secedentibus. Curt. no. 2842. On 

 rotten bits of wood in swamps, Sept., South Carolina, M. A. 

 Curtis. 



Pileus 1 J inch across, campanulate, then expanded, umbonate, 

 smooth, virgate, whitish with the centre dark ; margin striate ; 

 flesh thin, stem nearly 3 inches high, 1 J line thick, fuliginous, 

 flexuous, nearly equal ; gills white, at length flesh-coloured, sub- 

 ventricose. Spores irregular. 



Evidently distinct from the other white-gilled Leptonice which 

 grow on wood. 



75. A. (Leptonia) variicolor, B. & C. Pileo umbilicato glabro 

 pallide fusco ; stipite farcto ; lamellis postice abrupte attenuatis 

 adnatis purpureo-albis. Curt. no. 5530. Amongst bushes in 

 damp ground, Connecticut, C. Wright. 



Pileus i-li inch broad, umbilicate, smooth, pale brown; 

 flesh thin; stem 2 inches high, 1| line thick, greenish blue, 

 smooth, stufl*ed with woolly fibres ; gills broad, distant, some- 

 what ventricose, abruptly attenuated behind, and adnate, pale 

 purplish white. Spores irregular, -^q^jj-q inch in diameter. 



Allied to A. asprellus. 



7Q. A. (Nolanea) quadratus, B. & C. Pileo membranaceo co- 

 nico demum reflexo aurantiaco-fusco ; stipite fistuloso aurantiaco- 

 luteo; lamellis carneo-aurantiacis latis ventricosis. Curt. no. 

 5735. Amongst wet mosses in pine swamps. New England, 

 C. J. Sprague. 



Pileus 1| inch across, membranaceous, at first obtusely coni- 

 cal, then depressed, striate, of a clear orange or brown orange ; 

 stem 3 inches high, tender, fistulose to the very top of the pileus, 

 orange-yellow ; gills very broad, ventricose, almost triangular, 

 at first adnexed, then decurrent as the pileus becomes depressed, 

 of a beautiful incarnate orange ; spores, when seen from above, 

 quadrangular, yyjo inch across, sometimes irregular. 



One of the most splendid and singular species of the genus. 



77. A. (Eccilia) pyrinus, B. & C. Graveolens; pileo umbili- 

 cato fusco ; stipite compresso fistuloso ; lamellis albidis. Curt, 

 no. 5066. In swampy ground, New England, C. J. Sprague. 



Pileus 1 inch across, at first broadly convex, then flat, umbi- 

 licate, dark brown in the centre, grey at the crenate edge ; stem 

 1| inch high, J-^ inch thick, hollow, at length compressed; 

 gills whitish, slightly decurrent ; spores irregular, angular. 

 Odour like that of ripe pears. 



78. A. (Naucoria) siparioides, B. & C. Pileo hemisphserico
