Agaricaceee 



PLUTE'OLUS Fr. 



Dim. of plutens, a shed. 



piuteoius. Pileus conical or bell-shaped, then expanded, rather fleshy, viscid, 

 margin at first straight and pressed to the stem. Gills free, rounded 

 behind. Stem somewhat cartilaginous, its substance different from that 

 of the pileus. 



Growing on wood. 



Spores rust or saffron color. Pluteus, the only genus having the same 

 structure, is separated by its salmon-colored spores. 



(Plate LXXVI.) 



PLUTEOLUS RETICULATUS. 

 About natural size. 



P. reticula'tus Pers. rete, a net. From the net-work of veins on 



the pileus. Pileus slightly fleshy, 

 bell-shaped, then expanded, sticky, 

 reticulate with anastomosing veins, 

 pale violaceous, striate on the margin. 

 Lamellae free, ventricose, crowded, 

 rusty-saffron. Stem hollow, fragile, 

 fibrillose, mealy at the top, white. 

 Spores elliptical, ferruginous, 10 

 13x5-6. 5/x. 



Pileus 1-2 in. broad. Stem 1-2 

 in. long, i2 lines thick. 



Decaying wood. Cattaraugus 

 county. September. 

 The specimens which I have referred to this species appear to be a 

 small form with the pileus scarcely more than an inch broad and merely 

 wrinkled on the disk, not distinctly reticulate as in the type. In the 

 dried specimens the pileus has assumed a dark violaceous color. The 

 dimensions of the spores have been taken from the American plant. I 

 do not find them given by any European author. Peck, 46th Rep.

In October, 1897, P- reticulatus grew in large quantities on a fallow 

 lot close by the University of Pennsylvania, Philadelphia. The lot was 

 thickly covered with tall heavy-stemmed weeds, a mat of which, from 

 the year before was present. The reticulations upon the cap are intri- 

 cate and distinct. I have not seen it since. 

 The whole plant is tender and of fine flavor.
