Yorkshire Naturalists in the Ripon District. 
The few Myxomycetes recorded included Badhamia panicea, Physarum 
nutans and P. virescens, Fuligo septica, commonly, Comatricha nigra, 
Reticularia lycoperdon , Trichia varia, Perichcena depvessa and P. corticalis, 
Stemonitis fusca and 5. herbatica. 
The Discomycetes were not numerous or, at any rate, they were too 
dry and shrivelled to be recognisable. The species collected were mainly 
obtained in Spa Gill Woods and Pickin Gill. The species marked ‘ M ’ 
were sent to me after the meeting, from Mackershaw Wood.

Conchology (Mrs. E. M. Morehouse) : — The weather was not suitable 
for good results among the molluscan fauna, and a brief resume gives the 
following results of the land species : — 
Saturday : Woods round Eavestone Lake — i mollusc. 
Sunday : Pickin Gill — i mollusc, 3 slugs. 
Monday : Spa Gill Woods— 4 molluscs, 2 slugs. 
On August 2nd, Thieves Gill was visited, when eight species of 
molluscs and two slugs were taken. All the above areas were particularly 
dry. 
On August 8th a small party of five members explored the Mackershaw 
Woods. Here they were able to give much more time to a small area, 
with better results ; hence the total of 17 molluscs, including two species 
of slugs, one of which was the very common Agriolimax agrestis 
(Linne), the only specimen of its kind seen during the week-end. Also : —
