NOTES ON BRISTOL FUNGI. 297 



The family Hyphomycetes has been very little attended to by 

 Bristol botanists, as is testified by the number of species claimed, 

 3 or 4 only out of about 260 of Cooke; 



In the ascigerous group of fungi the Eristol botanists have more 

 to show. Of the primary division, Elvellacei, and the genus 

 MorcJieUa, one only is found in Crotch's list, the edible morel. 

 A marked form used to grow in the grounds of Blaize Castle, but 

 scarcely specifically distinct. Spathularia has a single species ; 

 two SelvellcB are recorded in Leigh Wood ; one Leotia, three 

 GeoglosscB. Of the genus Peziza — of which 198 species are 

 described in Cooke's work — 26 only are given in Crotch's paper. 

 The greater number of the genus are minute and difficult 

 of determination, as there are few authentic specimens in 

 existence, and to this we must attribute the paucity of species in 

 the Bristol list. Of the other genera of the order only 5 species 

 are mentioned out of 72 of Cooke. 



Of ascigerous Hypogei in the genus Tuher, 8 are named in 

 Crotch out of 10 by Cooke ; of other genera of the order 6, to 

 16 of Cook. 



Of the extensive order Sphceriacei, about 70 are recorded for 

 Bristol in the old genus Sphceria alone, while Cooke gives about 

 487, which have been divided into numerous genera of late years, 

 every writer creating new genera out of the old genus Spharia 

 just as the fit seizes him. Four or five other genera complete 

 Mr. Crotch's list. 



It is evident from the numbers represented in the latter, 

 compared with those of Mr. Cooke, that much requires to be done 

 in the Bristol district, especially in the more minute and obscure 

 -genera, in order to have a fair representation of its mycology. A 

 work of this kind can only be achieved by those resident on the 

 spot ; and to do it successfully those who take it in hand would 

 require the assistance of a good library and an herbarium for 

 comparison, as no plates or descriptive works can compensate for 

 the absence of the latter. One of the first aims of the student 

 should be the acquisition of dried specimens of all those fungi
