AGARICUS. 145 



Davao, in sunny pastures, not common. 



This species resembles A. argenteus Braendle and A. argyropotamicus 

 Speg. ; it. differs from them in the pileus' being conical at first, the disk's 

 shining like the periphery, unchanging flesh, and eguttulate spores. 



A. (Psalliota) manilensis Copeland. Pileus convex, smooth, squam- 

 ulose with disk flat and dark brown; toward the margin, where the scales 

 are sparse, becoming white, subfleshy; gills free, rounded toward the stipe, 

 turning from rose to dark-brown; spores about 7.5 by 4 p, obtuse, oblique 

 at the base; stipe 5 cm. high, 2.5 mm. thick, equal, naked, smooth, hardly 

 solid; annulus fixed, entire, convex upward. 



Manila, in lawns. 



Resembles A. haematospermiis Bull, and A. dy spines B. & Br. 



A. (Psalliota) perfuscus Copeland. Entire fungus brown, darkening 

 with age, odorless, with the flavor of A. campestris; pileus early expanded, 

 3 to 4 cm. wide, undulate, squamulose, subfleshy, disk slightly depressed, 

 margin strongly but deciduously appendaged; gills free, close, obtuse at 

 both ends, 4 mm. deep; spores elliptical, 6 to 6.5 by 4.5 //., obscurely 1- or 

 2-guttulate; stipe 3 to 4 cm. high, 3 to 4 mm. thick equal, firm, naked, 

 subhollow; annulus high up, fugacious. 



Manila, subgregarious on manured ground in the old botanical garden. 



Resembles A. insinuatus Cooke and A. haematospermus Bull. 



Lepiota chlorospora Copeland. Pileus fleshy, passing from globose 

 through campanulate to broadly conical, 8 cm. wide, 4 cm. high, the 

 periphery sometimes explanate, disk with a brown, entire or fissured cap, 

 periphery sparsely clothed with pale brown scales and fibers, white near 

 the entire or subciliate margin; gills free, remote, 5 cm. long, 8 mm. 

 deep, crowded, narrowed toward the stipe, white at first, turning a 

 greenish-blue, their edges made of hyaline vesicles 25 to 35 by 20 n; 

 spores hyaline-green, 8 by 5 /*, smooth, short-stalked, each with a single 

 large globule containing the green pigment; stipe 8 to 10 cm. high, 6 to 8 

 mm. thick, straight or crooked, knotted, firmly attached to the pileus, 

 brown outside and inside, with white pith; annulus 1 cm. broad, conspic- 

 uous, fixed, persistent, split in its own plane, white above until discolored 

 by the spores. 



Manila, in lawns. 



Distinguished from L. esculenta (Massee) Sacc. and Sydow by the brown 

 scales and fixed annulus. Massee established the genus Chlorophyllum 

 for these green-spored species; but it seems to me better to keep them in 

 Lepiota and extend its characterization sufficiently to cover them. The 

 spores are of the same color as those of Aspergillus glauous. 



L. manilensis Copeland. Flavor excellent, odor almost none; pileus 

 5 to 9 cm. wide, campanulate-conical, later flat, subumbonate, striate near 

 the margin, the disk densely clothed with minute brown scales, which 

 become sparse toward the margin; flesh whitish, unchanging; gills free, 

 not attached to a collar, crowded, deep, whitish, subacute at both ends; 

 spores variable, commonly 10 by 6 to 7 n, the largest 13 to 15 by 7.5 to 9 

 n, hyaline; stipe 10 cm. or less high, 1 cm. thick, firm, equal or somewhat
