FUNGI. 
Puccinia iridis at Scarborough. —I found Puccinia 
iridis Wallr. recently, on cultivated Iris in some gardens in 
Scarborough. On examination an abundance of teleuto- 
spores were seen along with uredospores. This disposes of 
the late Dr. Plowright’s theory ‘that the form which occurs 
on our cultivated Irises is different from that on our native 
species, because he could not find any teleutospores in the 
former ’ (see Grove ‘ Brit. Rust Fungi,’ p. 231). In the present 
case I found them freely, and they agreed in every respect 
with those of P. wvidis. This fungus is new to Yorkshire—

Apple Tree Mildew near Scarborough. —Mr. W. Pearson, 
of Scarborough, has handed to me some apples from Ebberston 
in this district, which have been attacked by the Apple Tree 
Mildew Podosphaera leucotricha Salm., a fungus which is new 
to Yorkshire. The quality of the fruit was much depreciated 
by the disease, the apples being small in size and studded with 
the perithecia of the fungus. Massee in ‘ Mildews, Rusts 
and Smuts,’ page 40 says: ‘ Parasitic on species of Pyrus. 
This is a very destructive parasite to the apple in many parts 
of the world.’ The specimens found were in the ascigerous or 
perfect stage which is apparently rare in this country, the 
oidium or conidial condition being that usually met with, in 
which the leaves are densely covered with the conidia which 
appear as whitish dust. According to Massee (loc. cit.), ‘it is 
believed that the mycelium of the fungus hibernates between 
the bud scales and gives rise to the white oidium condition 
of the fungus.’—T. B. Ror, Scarborough.

The Norwich Museum has issued ‘ Descriptive Notes on Some British 
Plants used in Witchcraft and Medicine,’ by James Hooper, 23 pages. 
Birkenhead has issued its Furst Annual Report of the Public Libraries, 
Museum and Avt Gallery. The Art Gallery and Museum were opened 
in 1912, and views are given in the report. 
One of the last official functions of the Lord Mayor and Lady Mayoress 
of Leeds (Mr. and Mrs. J. E. Bedford, F.G.S.), before retiring from 
office, was to hold a Conversazione in the hall of the Literary and Philo- 
sophical Society. The Society’s museum at Leeds contains many inter- 
esting objects from Mr. Bedford’s collection. 
A General Guide to the Collections in the Manchester Museum: Man- 
chester Musewm Handbook, No. 97, has been issued (Longmans, Green 
& Co., 3d., 66 pages). The recent important addition of the Egyptian 
rooms to the museum accounts for a good proportion of the handbook, 
though the geological, zoological and botanical sections are well repre- 
sented. The guide book is necessarily somewhat condensed. It is well 
illustrated, and there is an excellent plan of the museum.
