Fungi (F. A. Mason) : — Comparatively few species of fungi were 
observed. Daldinia concentrica, the pyrenomycete, so frequently found 
on ash, was here found on birch, one small tree with a trunk about 2 in. 
in diameter, was found supporting a considerable number of fructifica- 
tions. It is an interesting fact that at Allerthorpe, a similar district, 
in which small birches flourish, D. concentvica occurs on the same host. 
Mr. W. G. Bramley collected agarics, and although all the species are 
common they are worth mention as being characteristic of such an 
area : Paxillus involutus, Tubavia furfuraceus , Omphalia umbellifera, 
Galera hypnorum and var. bryorum, Panceolus campanulatus and 
Stropharia semiglobata. 
The St. George’s mushroom, Tricholoma gambosum, occurred* sparsely 
distributed. Among some discomycetes collected by Miss D. Wooff 
were Peziza luteo-nitens B. and Br., and Cilliaria hirta (Schum.) Boud., 
both of which are additional to the flora of S.E. Div. (V.C. 61).

species, records of recovery of ringed birds, and notices of occurrence of 
rarities. One of the most valuable series of articles is that dealing with
