ber, 1885.) In these lists names in italics denote species not yet 

 recorded for Scotland, and those marked thus (;/) denote addi- 

 tions not yet recorded for the districts. Notices of the occurrence 

 of the remaining species in each district will be found in the 

 Scottish Naturalist, chiefly in the numerous supplements to Myco- 

 logia Scotica, issued for a time by Mr. Stevenson alone, and latterly 

 by Mr. Stevenson and myself conjointly. 



The additions to "Tay" are the result chiefly of the work of 

 Mr. Stevenson in Forfarshire, and of Dr. F. B. White in Perthshire ; 

 but I have been able to add a few from the neighbourhood of 

 Montrose. 



The list for " Dee " rests almost entirely on my own work 

 among the fungi in the neighbourhood of Aberdeen during the 

 past two or three years. I have found the microscopic groups 

 quite a wide enough field of study, and accordingly have done 

 little among the Hymenomycetes and the Helvellacei, which in 

 " Dee " still greatly need working out, and that they will repay 

 study we may infer from the wonderful results of Dr. Keith's 

 labours among them in the neighbouring province of " Moray." 



A large proportion of the species in the subjoined lists were new 

 to the flora of Scotland when published from the districts of 

 "Dee" and "Tay" in the supplements; and a considerable 

 number were new to the British lists, several never having been 

 previously described. A glance at the present lists will show that 

 a considerable portion of the species in that for Dee are still un- 

 published records. 



I regret that I have no information for the part of the province 

 of " Forth " that lies within the bounds of the Union. There 

 does not seem to be any worker in the Fungi now resident in that 

 part of the East of Scotland. Let us hope that this will not long 

 continue to be the case, and that some worthy successor to 

 Greville may resume the study of Mycology in " Forth," so well 

 begun by him. 



The nomenclature and arrangement have been retained as near 

 as possible to those in the Mycologia Scotica for convenience of 

 reference ; but a few changes have been introduced where allied 

 forms were widely separated under the arrangement there em- 

 ployed, and where, as under Peronospora^ species were placed 

 under manifestly wrong genera. It must be borne in mind, how- 

 ever, that a very considerable portion of the fungi enumerated as
