which suffered considerable damage from the snowstorms of 
March, 1916, and January, 1918, and here this fungus is very 
plentiful. The aecidia which appear in June are very con- 
spicuous on the fruits of the Hawthorn. 
Chrysomyxa Pyrolce Rostr. is found on the leaves of Pyrola 
minor in some of the woods in the district round Pains wick. 
The uredospores appear in the early summer, and are not 
followed by any teleutospores. 
Puccinia Thesii Chaill. Thesium humifusum in its 
Whittington habitat seldom produces flowers in the early 
summer owing to the attacks of this parasite. Later on the 
plant recovers, and flowers are produced, and may often be 
found as late as October. In this fungus it is the aecidium-stage 
that is most frequent ; I have not seen the other spore forms. 
Puccinia Bulbocastani Fckl. In the Proceedings of last year 
Mr. Montgomrey mentioned that Carum Bulbocastanum had 
recently been, found in a cornfield near Cheltenham. Its parasite 
has been introduced with it. This Puccinia has aecidiospores 
and teleutospores, both of which were produced last year, while 
Puccinia tumida, which is found on the closely allied Conopodium 
majus, has teleutospores only. 
Uromyces Poce Raben. In this the aecidia are found on 
species of Ranunculus, especially on R. Ficaria, and the uredo- 
spores and teleutospores on the common species of Poa. Last 
summer I found this parasite on Poa palustris at the Lower 
Lode near TewTesbury, on the west bank of the Severn. This 
Poa is not given as a host of this fungus in works on the British 
Uredinales. 
Since my list of Gloucestershire Mosses appeared in the 
Proceedings 1 of this Club for 1914, I have found the following 
additional species : — 
Dicranella cerviculata Schp. On Lias clay at the old Pilford 
Brickworks, Pilley, Leckhampton, with the Hepatic Aplozia 
ccespiticia. This moss is usually found growing on peat. 
Dicranum strictum Schleich. On tree stump, Chatcombe 
Wood, near Cheltenham.
