KEVISION OP THE UREDINE£ AND OP THE USTILAGItfEU 



Sicbmitted to the Meeting of the Scottish Cryptogenic Society in 



By Prof. James W. H. Trail, A.M., M.D., F.L.S. 

 HE publication of Mr. Plowright's " Monograph of the 



X British Uredineae and the Ustilagineae " in the early part 

 of 1889 induced me to select these groups of fungi in continuance 

 of the series of " Revisions" that I have been laying before the 

 Scottish Cryptogamic Society at its later annual meetings. 



So great an advance has been made in our knowledge of the 

 biology and of the Scotch distribution of the species of both 

 groups since the year 1879, when the Mycologia Scotica was 

 published, that the subjoined list will be found to differ very widely 

 from the lists in that work alike in the nomenclature and in arrange- 

 ment of the fungi enumerated, and very numerous additions to 

 the areas of distribution will be observed, especially under a few 

 of the districts. 



Among the Uredinece the interval is in so far bridged by a paper 

 on " Hetercecism in the Uredines" which was published in the 

 first volume (1883 — 84) of the New Series of this Journal, but in 

 that paper there is no attempt to indicate distribution. 



The signs and contractions employed below are similar to those employed in 

 the "Revisions" already issued. The mark (!) denotes that the record is a 

 personal one, i.e., if it follows the name of a locality or district it denotes that 

 I have myself seen the fungus growing there ; if it follows the month or season, 

 or the name of a host-plant, it denotes that I have found it at the time and on 

 the plant indicated. 



The names used in the Mycologia Scotica are given in brackets, with the 

 numbers under which they stand in that work. The letters p.p. (standing for 

 pro parte) denote that the name in the Mycologia Scotica covers more than 

 one species as now understood ; and that the "species " in the subjoined list 

 corresponds only in part to the name put after it in brackets. An asterisk is 

 prefixed to the names of species added to Scotch records since 1879, and also 

 to the new stages observed since then in the species with a complex cycle of 

 development, of which only one stage, or at least not all, had been previously 

 found in Scotland. New records of food plants are indicated in the same way. 

 New district-records are in italics ; those previously given in the Mycologia 

 being in ordinary type.
