KAUCOEIA. 151 



NAUCOEIA. Fries, (figs. 8, 9, p. 3.) 



Pileus more or less fleshy, conical, or convex tlien ex- 

 panded and becoming flattened, margin at first incurved ; 

 stem central, cartilaginous, hollow or spongy inside; gills 

 free, adnexed, or adnate, not decurrent; veil fugacious, 

 squamulose, or absent. 



Naucoria (as a subgenus of Agariens), Tries, Syst. Myc, i. 

 p. 260 ; Cke., Hdbk, p. 173. 



The species are mostly small and usually of a brownish 

 colour, growing on the ground among grass, rarely on wood. 

 Naucoria is most nearly allied to Galera, but distinguished 

 by the pileus being more fleshy, and not striate, and more 

 especially in the margin being incurved when young, this 

 last character, however, is rather indistinct in a few species, 

 as N. cucumis, N. cidaris, and N. hadipes, nevertheless the 

 sum of characters retain these species in the present genus. 



Naucoria agrees morphologically with Leptonia and Collijbia. 



The species included under the present tribe are very 

 variable amongst themselves, but all agree in the following 

 characters. Spores ferruginous ; stem cartilaginous ; thts 

 more or less fleshy pileus having the margin at first incurved.
