Last year Mr. W. A. Thwaites, of Masham, continued his 

 investig-ations into the funi^us flora of Masham and Swinton, 

 commenced in August 1901 (vide 'The Naturalist,' January 

 1902, pp. 21-31). The district worked Hes between the two 

 places named and is mostly in the valley of the Burn;. 116 

 species have been added to the 416 met with in 1901. They 

 will be found classified in the following- list, with host, habitat, 

 and date when collected, added. None are new to the Britisli 

 flora. . A few hosts, attacked by parasitic fungi, are given in 

 addition to those generally found in the text books, viz.: — 

 Ccvoma orchidis on Gymnodena conopsea ; and Dasyscvpha calvcinu, 

 the larch disease on the Weymouth pine and Spruce fir. The 

 number of herbaceous-plant parasites in the shape of Uredines 

 is a noticeable feature; 17 were noted in 1901, and to these 21 

 more have been added. Out of 66 British species of Helotmm 

 Mr. Thwaites has succeeded in collecting- no less than 20. The 

 dates show that fungi of one kind or another are to be met with 

 all the year round.
