A few dead insects bearing either parasitic or saprophytic fungi were 
collected and I am indebted to Mr. T. Petch for their examination. A 
fly (species undetermined) taken in the net by Mr. J. R. Dibb, was 
parasitised by Empusa muscce Cohn. Miss K. Morehouse collected a 
number of specimens of dead flies at Eavestone which had been attacked 
by Fntomophthora americana Thaxter, while the only fungus found 
among a mixed lot of insects from the district was Mucor miicedo on 
a Tipulid, on which, doubtless, it occurred as a saprophyte. 
There were fewer Uredines than might have been expected, and those 
seen were mostly on the plants growing about Eavestone Lake or in the 
marshy fields traversed at the head of Spa Gill.

The ‘ smut,’ Entyloma ranunculi , occurred on Ranunculus repens at 
Eavestone. 
Microscopic fungi received but little attention, although they were 
present in plenty. In addition to the few species that could be identified 
in the field, material since examined has yielded a list containing some 
noteworthy species.
