hyphae up to 210u high. These branched penicillately, forming 
a head of flask shaped branches which produced very long chains 
of globose, smooth, hyaline conidia which were slightly tinted 
brown and measured 3 diameter. In the specimen examined 
by Jensen the mycelium formed non-zonate patches; our speci- 
men, however, showed slight zonation. 
RARE FUNGI. 
During 1921 we met with the following rare fungi: 
Oospora ochracea (Corda) Sacc. and Roum. Forming gre- 
garious pinkish-grey velvety tufts on apricot jam. 
Tetraploa aristata B. and Br. On grass (probably Poa pra- 
tensis) cut and thrown into a heap; also on living roots of grass. 
Sporodesmium myrianum Desm. On Psamma arenaria Borth, 
North Wales and Sandwich, Kent. 
In conclusion we thank Mr W. B. Grove for valuable help in 
the identification of some of the above species. 
REVIEW. 
British Basidiomycetae, a Handbook of the larger British Fungi, 
by CARLETON REA. Pp. xii + 799. £1. Ios. net. Cambridge 
University Press. 1922. 
The publication of this important work, embodying the accu- 
mulated knowledge of thirty years’ work in the field, has been 
awaited by members of the British Mycological Society with a 
peculiar interest. 
It is well known how Mr Rea acted as Secretary to the Society 
for many years, practically managed the Forays singlehanded, 
and was responsible for the naming and listing of the huge 
quantities of material collected. The beautiful coloured plates, 
painted by Mrs Rea, were invaluable for placing on permanent 
record rare or new species. 
The work has been delayed by printing and publishing 
difficulties arising from the War. The author is to be congratu- 
lated on the success of his great effort. 
The Handbook will be welcomed not only by all Mycologists 
in this country, but also by Continental botanists, and will be 
assigned a worthy place among the most esteemed Fungus 
Floras of France, Sweden or Germany. 
An appreciation of its merits can only be arrived at after a 
prolonged study of its contents, and considerable experience in 
comparing the groupings and descriptions with the Fungi them- 
selves, but even a limited practical acquaintance with it is 
sufficient to demonstrate its value. The time and labour required 
in its compilation must have been great. 
Mr Rea deals in this volume with the Basidiomycetes alone— 
a sufficiently large field!
