The Leptoniæ are related to the Clitopili as the Collybiæ are to the Clitocybæ. The species are small, elegant, brightly colored, inodorous (except A. incanus), and abound _in rainy weather_. Gregarious or growing in troops; on the ground, commonly on dry mossy pastures, but also in marshy places. _Stevenson._ Six American species reported. I have not seen any. =NOLA´NEA= Fr. _Nola_, a little bell. (Plate LXVII.) [Illustration: Nolanea pascua. About natural size. ] Rosy-spored. =Stem= _tubed_, the tube more rarely stuffed with a pith, _cartilaginous_. =Pileus= somewhat membranaceous, _bell-shaped_, somewhat papillate, striate and sometimes even, sometimes also clothed with flocci, _margin straight and at the first pressed to the stem_, and not involute. =Gills= free or adfixed, and not decurrent. _Fries_. Nolanea agrees with Leptonia and Eccilia among the pink-spored species. It corresponds with Mycena, Galera and Psathyra. Several Entolomata are nearly allied. The species are thin and slender, commonly inodorous and fragile, though some of them are tough. Growing on the ground in summer and autumn. _Stevenson._ Seven American species reported. None seen by writer. _Peck_, Rep. 24, 26, 35, 39, 50. =ECCI´LIA= Fr. _Gr_—I hollow out. (Plate LXVIII.) [Illustration: ECCILIA ATROPUNCTA. Two-thirds natural size. ] =Stem= _cartilaginous_, tubular (the tube hollow or stuffed), expanded upward into the _pileus_, which is somewhat membranaceous and at the first turned inward at the margin. =Gills= attenuated behind, truly decurrent, becoming more so when the pileus is depressed, and not separating as those of Nolanea. Corresponding in structure with Omphalia of the white-spored and Tubaria of the brown-spored series. Allied to Clitopilus in the decurrent gills, but separated by the cartilaginous, smooth stem. (Plate LXIX.) [Illustration: ECCILIA CARNEO-GRISEA. Natural size. ECCILIA ATROPUNCTA. ] =E. car´neo-gri´sea= B. and Br.—_caro_, flesh; _griseus_, gray. =Pileus= about 1 in. broad, gray flesh-color, umbilicate, striate, delicately dotted, margin slightly glittering with dark particles. =Stem= about 1½ in. long, slender, fibrous-hollow upward, wavy, of the same color as the pileus, shining, smooth, white-downy at the base. =Gills= adnato-decurrent, somewhat undulated, distant, rosy, the irregular margin darker. _Stevenson._ =Spores= irregularly oblong, rough, 7×5µ _Massee_. Nova Scotia, _Dr. Somers_. New Jersey, _E.B. Sterling_, August, 1897; Eagle’s Mere, Pa., common under pines, _McIlvaine_. This neat little species is sweet and pleasant raw, and when cooked makes an agreeable dish. European authorities give the taste as unpleasant, but there is nothing of the sort about the American representative.
