Presidential Address. Carleton Rea. 15 
Bind 1, No. 5. He therein regroups the species of Mycena with 
smooth spores into two divisions based on the characters of the 
cystidia. In the first, the CILIATAE, he places all those having 
their free apical portion conical, cylindrical, hair-shaped or 
subulate, and in the second, the GRANULATAE, he puts all those 
having clavate pyriform or obovate cystidia beset with warts 
or setae on their free portion. This is a very workable division 
of this genus and one that I think we might very usefully adopt, 
but it will take some time before we can work out the form of 
the cystidia in all our British species and therefore I crave the 
assistance of all our members in so doing. 
In 1914, the eminent American mycologist, Professor E. A. 
Burt, commenced his splendid series of monographs on the genera 
of the Thelephoraceae of North America. Up to the present 
these include monographs of the following genera: Thelephora, 
Craterellus, Cyphella, Exobasidium, Tremellodendron, Eich- 
leriella, Sebacina, Hypochnus, Septobasidium, Coniophora, 
Aleurodiscus, Hymenochaete and Stereum. These monographs 
are models of careful work and original research and are indis- 
pensable to a thorough knowledge of this group, and I feel that 
all students impatiently await the completion of this series. In 
1909, l’Abbé H. Bourdot and A. Galzin began an account of the 
“Hyménomyceétes de France” in the Bulletin de la Société 
Mycologique de France, vol. xxv, and several other instalments 
have appeared in succeeding years, but it is unfortunately far 
from completion at the present time. It is based on Patouillard’s 
classification but is especially valuable for the wealth of detail 
that it gives respecting the Thelephoraceae, Hydnaceae, Auricu- 
lariaceae, Tremellaceae and Tulasnellaceae. They have in a 
great measure remodelled the definitions of the species of Thele- 
phoraceae and resupinate Hydnaceae and in conjunction with the 
investigations of v. Hoehnel, v. Hoehnel and Litschauer, l’Abbé 
Bresadola and Professor Burt compelled us to reinvestigate our 
own British species in this group. It is somewhat unfortunate 
that Bourdot and Galzin have not followed the laws of inter- 
national nomenclature and that they rarely condescend to say 
what name the new species described by them was previously 
known by to the older school of Friesian mycologists. Take Odontia 
bicolor (A. & S.) Bres. as an instance which Miss Wakefield has 
clearly shown was known to Berkeley by the name of Grandinia 
mucida Fr. Again, the well-known Peniophora hydnoides Cke. & 
Massee has no cross reference in their synopsis of that genus 
but suddenly crops up as Odontia conspersa Bres., a specific 
name that cannot be maintained under any rules of nomen- 
clature. It is however a very important work and I think we 
are very grateful to Miss Wakefield and Mr A. A. Pearson for
