Yorkshire Naturalists at Market Weighton.

The botanists were under the care of Messrs. W. Robinson, 

 J.J. Marshall and W. Ingham. They were able to report that 

 the moss Dicranum undulatum still grew in its only known 

 station for the whole of the British Isles. Fungi were not very 

 common, but the ordinary Morel was found, as well as Mitro- 

 phera semilihera. In addition, Pluteus cervinus and Hypholoma 

 fascicularis were obtained by Mr. A. E. Peck. 



The conchologists were in full force, and were under the 

 leadership of Messrs. Taylor, Musham, Roebuck and Hutton, 

 but they were not successful in finding Acanthinula aculeata. 



Mr. S. H. Smith favours us with a lengthy report of the birds 

 observed. In this he records that the nest of a missel thrush 

 with three eggs was found in a willow tree fork, only two feet 

 above the ground.
