579. A. cmstiliniformis Bull. Pileus pale-whitish tan, most 

 frequently pale-yellowish or brick-colour at the disc, fleshy, con- 

 vexo-plane, obtuse or slightly gibbous with an obtuse umbo, 

 somewhat repand, even, smooth, at first slightly viscid, not zoned ; 

 flesh hyaline when moist. Stem stuffed, then hollow, stout, 

 somewhat bulbous, white, naked, white-squamulose at the apex. 

 Gills rounded-adnexed, crowded, narrowed, 2 mm. (i lin.) broad 

 and linear, thin, whitish then clay-colour, at length date-brown, 

 the tmequal edge guttate, distilling watery drops in wet weather, 

 spotted when dry. 



Veil quite awanting. Odour strong, foetid, of radish. Very variable in 

 stature; the stem, however, is never elongated as in A. elatus, &c.; in smaller 

 specimens equal, pileus regular, gills almost adnate. 



In mixed woods. Common. Aug.-Nov. 



Forming large rings. Smell like that of the flowers of the common laurel. 

 A. planus Sow. is apparently a small form of this species, M.J.B. Poison- 

 ous. Considered very dangerous. Pileus 2.5-10 cent. (1-4 in.) broad. Spores 

 ellipsoid, 10-12x5-7 mk. K.; 9x5 mk. W.G.S. Name crustulum, a 

 small pie.; forma, form. From the shape of the pileus. Bull. t. 308, 546.

580. A. elatus Batsch. Pileus as much as 7.5 cent. (3 in.) 

 broad, tan-colour, fleshy, convex then flattened, obtuse, even, 

 smooth, slightly viscid when moist, opaque becoming pale-tan 

 when dry, margin very thin. Stem 10 cent. (4 in.) long, 8 mm. 

 (4 lin.) thick, stuffed, equal and cylindrical, tense and straight, 

 but the whole constantly twisted with spiral fibres, adpressedly 

 fibrillose, pale-whitish, white-mealy at the apex. Gills rounded, 

 with a small decurrent tooth, crowded, 6 mm. (3 lin). broad, 

 not spotted, arid, not distilling drops, quite entire, pale cin- 

 namon. 



Pileus sometimes only 2.5 cent, (i in.) broad. Odour of radish very strong. 

 Veil absolutely none. In larger specimens the stem has an appendage in the 

 form of an ovate villous bulb, which is covered over with fir-leaves. Batsch f. 

 108 represents it perfectly; it differs, however, entirely from Cortin aritis elatior, 

 which Persoon described for it. 



In pine wood, among moss and leaves. Uncommon. Oct.-Nov.
