442 FUNGUS-FLOEA. 



flesh thick at the disc, margin thin ; gills decuirent, about 

 1 line broad, closely crowded, lemon-yellow, margin entire ; 

 stem 2-2|- in. long, 2 lines thick, yellow, with brownish 

 fibrils, solid.

 Cke., Hdbk., p. 62; Cke., Illustr., pi. 127. 



On an oak tub in a conservatory. 



Clustered. The sour smell, strong acrid taste, colour, and 

 habit suggest the genus Hypholoma, as does also the habitat. 

 I have found what appears to be exactly the same thing 

 along with typical Hypholoma fascicularis on a stump, and 

 cannot but think the present is nothing more than an ab- 

 normal form of Hypholoma with the gills more or less decur- 

 rent and permanently sterile, hence not becoming tinged 

 with the dark spores. Several instances of dark-spored species 

 with sterile gills that remain pale, are on record'. 



LACCAEIA, B. & Br.. 



Pileus convex then umbilicate or depressed, flesh thin ; 

 gills broadly adnate, sometimes with a decurrent tooth, 

 becoming mealy with the copious subglobose, minutely 

 warted white spores ; stem central, externally fibrous ; veil 

 not evident.

 370. 



Clitocyhe (as a subgenus of Agaricus), "Fries, Syst. Myc, i. 

 p. 70; Cke., Hdbk., p. 46. 



Separated from Clitocyhe on account of the broadly adnate 

 gills becoming powdered with the white, subglobose, mi- 

 nutely warted or echinulate spores. 



This is clearly quite as distinct from the genus Agaricus 

 as Itussula and Lactarius, and cannot with any justice be 

 included in the subgenus Clytocyhe. We have several very 

 distinct forms from Ceylon, besides our own A. laccaius, hellus, 

 and one or two continental species. The amethyst-coloured 

 form usually referred to A. laccatus is probably distinct.
