Read 28th September, 1897.] 
On 27th December, 1892, I submitted to the Society a list of the 
Ustilaginee of North Ayrshire,* in which were enumerated 16 
species, with particulars of the host-plants on which they had 
been observed by me, and the localities in which they had 
occurred. On 24th April, 1894, a similar list of Peronosporez, 
enumerating 21 species, was also communicated to the Society.t 
Since the dates when these papers were read, several additional 
‘species have been detected within the district, while certain fungi 
have been gathered on host-plants other than those formerly: 
indicated, and in localities not previously reported. 
In the following supplementary list, the mark “{” is prefixed 
to the names of species not recorded for Ayrshire in my former 
papers, while additions to the number of host-plants and localities 
are similarly indicated :—
