species of North American Fungi. 427 



infundibuliform, smooth, dirty white ; margin finely revolute ; 

 stem 1 inch high, not a Hne thick, nearly smooth above, lanu- 

 ginous, below pale brown ; gills extremely narrow, entire, often 

 dichotomous, white, strongly decurrent. Spores white. 



An elegant little species, and quite a dwarf in a genus con- 

 taining many of the most magnificent fungi. 



31. Lentinus Micheneri, n. s. Pileo sinuato sublobato um- 

 bilicato glabro ; stipite brevi incurvo spongioso-velutino fusco ; 

 lamellis latiusculis laceratis crassis breviter decurrentibus. Cm't. 

 no. 3962. On decaying timber, Pennsylvania, Dr. Michener. 



Pileus about 2 inches across, irregular, lobed and siuuated, 

 umbilicate, smooth; stem about 1 inch high, 2 lines or more 

 thick, clothed wdth brown spongy down, but more especially 

 below; gills rather thick, broadish, shortly decurrent. 



A very distinct species, to which we can point out no close ally. 

 The gills resemble those of L. cochleaius. 



32. Lentinus paUidus, n. s. Csespitosus ; pileo convexo mar- 

 gine repando sordide luteo-albo ; stipite fibroso-squamoso deor- 

 sum furfuraceo, lamellis decurrentibus crassiusculis. Curt. no. 

 2586. On dead wood. South CaroHna, H. W. Ravenel, Esq. 



Csespitose, connate at the base. Pileus 3-4 inches broad, 

 convex, slightly depressed in the centre, dingy yellow-white, 

 margin repand ; stem 4 inches high, | of an inch or more thick, 

 rough above, with a few coarse squarrose fibres, furfuraceous 

 below. Gills white, decurrent, lacerated, interstices venous. 

 Spores white. 



Allied to L. lepideus, but the pileus is quite smooth, and the 

 stem rough with linear processes torn from its substance. 



33. Panus levis, n. s. Pileo plano-depresso \'illoso, stipite 

 sursum attenuato tomentoso deorsum strigoso pallidis ; lamellis 

 latis distantibus integris deorsum villosis. Curt. no. 2949 ; 

 Rav. no. 808. On trunks of trees, Sept., H. W. Ravenel, Esq. 



Pileus 3 inches across, orbicular, slightly depressed, white, 

 clothed in the centre with long intricate villous rather delicate 

 hairs, which are shorter and more matted towards the inflected 

 margin. Substance rather thin. Stem 3 inches high, ^ an inch 

 thick, attenuated upwards, generally excentric, sometimes lateral, 

 not rooting, sohd, strigose below, closely villous like the margin of 

 the pileus above. Gills rather broad, entire, decurrent, but not to a 

 great degree ; the interstices even above, behind clothed with the 

 same coat as the top of the stem. Spores white. 



A most distinct species, remarkable for its great lightness 

 when dry, and the long, villous, but not compressed or compound, 

 flocci of the pileus. Sometimes the centre of the pileus becomes 

 quite smooth when old, 



34. Panus alliaceus, n. s. Pileo sessili postice subeffuso al-
