Omphalia campanella sparsa n. var. 



Pileus convex, with a small umbilicus ; lamellae yellow, decur- 

 rent, rather broad, subdistant, interspaces veiny; stem long, 

 slender, equal, straight, glabrous, with a copious tawny tomen- 

 tum at the base and sometimes a slight tawny mealiness at the 

 top, hollow, black or brownish black. 



Scattered or loosely gregarious. Among fallen leaves and 

 sticks under pine trees. Bolton. August. Several varieties 

 of this species have already been described but this corresponds 

 to none of them. In its habitat and mode of growth it ap- 

 proaches varieties b a d i p e s and papillata, from the for- 

 mer of which it differs in the color and character of both pileus 

 and stem, and from the latter in the shape of the pileus. The 

 small umbilicus is not deep and it sometimes contains a small 

 blackish papilla. The pileus is 4-6 lines broad and the stem 

 1-2 inches long but scarcely more than half a line thick. 



Nyctalis asterophora Fr. 



This fungus with us is nearly always affected by what seems 

 to be a parasitic fungus which covers the pileus with a pulveru- 

 lent coat of tawny brown or cervine stellate spores. This ap- 

 pears to prevent in some cases the development of the lamellae 

 and consequently of its own spores. But the form having 

 lamellae does sometimes occur. Such specimens were found 

 near Bolton in August. When young the pileus is white and 

 its margin involute. It has a farinaceous taste and odor. The 

 stem also is at first white externally, but brown within. It is 

 stuffed or hollow. The lamellae are rather distant and nar- 

 row. Such specimens sometimes become pulverulent and dis- 

 colored after collection and before they can be dried. 



Lentinus ursinus Fr. 



This species varies beyond the limits assigned to it in the 

 description. Specimens were found growing on an old pros- 

 trate birch trunk, Betula lutea, near Bolton, that were 

 from 2-4 inches broad. When young the pileus is convex with 

 an involute margin, glabrous and whitish, but with advancing
