GUIDE TO THE MODELS OF FUNGI. 



— t 



obtuse umbo, smooth, at first slightly viscid, not zoned ; flesh hyaline 

 when moist ; gills rounded-adnexed, crowded, whitish, then clay- 

 coloured, at length brown, distilling drops in wet weather; stalk 

 stuffed, then hollow, stout, somewhat bulbous, white, naked, white- 

 squamulose at apex; veil and ring absent. Odour strong, like 

 prussic acid or radish, but foetid and disgusting ; very poisonous. 



A. cnistuliniformis is common in mixed woods, where it fre- 

 quently grows in rings of immense size; it is often confounded 

 with A. fastibilis, and as frequently mistaken for A. arvensis. It 

 differs from the latter in its odour, in the attachment of the gills 

 to the stem, in the absence of a ring, and in its habitat ; the superficial 

 resemblance between the two plants is however strong. As both 

 fungi are very variable, no single character should be held conclusive; 

 all the distinctive characters should be taken together. 



Sub-genus 17. Naucoria. — There are forty-one British species 

 of Naucoria, only one of which is represented by a model. Naucoria 

 — :px agrees in structure with Collybia, Lcptonia, 

 jiLv^ and Psilocybe ; but the spores are ferru- 



r^^, ( ginous, not white, rosy, or purple. The 



_ . > \ species, however, differ much among them- 



selves in details of structure and habit ; 

 they are generally small, and are either 

 terrestrial or grow on stumps, twigs, saw- 

 dust, decaying leaves, grass, etc. No 

 species of Naucoria is edible.

Subgenus i8. Galcra. — There are 

 fourteen British species of Galcra, only 

 one of which is represented by a model. 

 Galcra agrees in .structure with Mycciia, 

 Nolauca, and Psnihyra ; but the spores are 

 ochreous-fi.rruginous, not white, rosy, or 

 purple. All the species are small in size 

 and autumnal.
