represented his trachodes of 1847, for the drawing is marked in 

 pencil with the alternative name A. [Psalliota) hypocarphus, 

 B. & Br. 



The figure of Psalliota poderes (No. 1,220) is marked by 

 Berkeley, " vel potius .4. pedilius, var." It represents a small 

 half-expanded specimen, total height 51 cms. and diameter of 

 pileus 5 cms. The pileus is slightly paler than that of Ps. 

 trachodes, but has the same brown cap at the apex. The base 

 of the stem is enclosed in a brownish sheathing volva with a 

 toothed margin, and as in Ps. trachodes there is an ample 

 partial veil. It only differs from the figure of trachodes in the 

 presence of the volva at the base of the stem, and as the volva 

 is floccose and frequently remains attached to the soil, this 

 difference is undoubtedly due to carelessness in collecting. 

 The brownish colour of the volva is probably an attempt to 

 represent the red earth stain. 



Psalliota pedilia,^. &Br., is Thwaites , No .1,221. The figure 

 is marked by him " ? same as 1,220," and to this has been 

 added later a protest against their separation, "I took them 

 for the same species when they were collected." The specimen 

 had just begun to expand. It is 7 cms. high ; pileus 3 cms. 

 high and 3"8 cms. in diameter ; stalk 1*9 cms. thick. Two- 

 thirds of the pileus is covered by a smooth brown hemispherical 

 cap, and the base of the stem is enclosed in a large whitish 

 spreading volva with the edge divided into triangular lobes. 

 The flesh of the stem and pileus is reddish in section. Berkeley 

 says that poderes differs in the hemispherical squamulose, 

 striate pileus, but this is only a matter of age, pedilia being 

 scarcely escaped from the volva, and considering the loose 

 structure of the volva it is not surprising that the younger 

 specimen possesses it to the greater extent. But the great 

 difference, " the presence of a large white ring," is an oversight, 

 for the figure of the section of pedilia shows the partial veil 

 between the gills and pileus quite distinctly. There is no 

 room for doubt that Thwaites' view was correct, and that 

 Psalliota poderes and Ps. pedilia are the same species. 



It is not uncommon at Peradeniya, where it usually grows 

 among grass in the open. The pilous is hemispherical at first,
