Yorkshire Naturalists at Pocklhigton. 



267 



The members continued their investigations on Bank HoHday, 

 the route taken being- from Pocklington, through Givendale, 

 over the Wolds to Millington, and back by the picturesque 

 MiUington springs and valley. The famous springs were 

 examined by the party, and in the dale itself attention was 

 drawn to those remarkable earthworks which are of a very 

 early date, and were described by Mr. Mortimer, of Driffield, as 

 habitation terraces. The botanists were successful in obtaining 

 212 species of flowering plants, together with a large number 

 of mosses, fungi, and lower forms of plant life. 



After dinner at Pocklington the meeting was held, Mr. G. T. 

 Porritt, F.L.S., Huddersfield, presiding. At this the various 

 reports of sections were presented. 



For the conchologists the Rev. F. H. Woods reports : — The 

 shells found were Helix virgata with variety submaritima, both 

 frequent on dry ground in pastures and the roadsides ; H. 

 nemoralis , on roadsides ; H. cantiana, on roadsides up the long 

 hill towards Warter, mostly of a reddish type ; H. arbiistoriim 

 with var. pallida, in the same locality. A very dark variety was 

 also taken in the wood on Major Duncombe's estate. In these 

 two cases one fancies that the different locality may have 

 indirectly influenced the colour, the dark specimens being found 

 among damp, mossy stones, the light coloured in dry places in 

 the open. H. rotundata, among mossy stumps in the same 

 wood ; H. ericetorum, one specimen was found ; H. hispida, 

 smooth variety ; Ancylus flttviatilis, abundant on the stones in 

 the brook in the valley above Millington, but only young speci- 

 mens. On Saturday we found Anodonta cygnea and Limncea 

 auricularia. I also found several young specimens of Ancylus 

 fluviatilis in the brook below the lake. This also yielded a fine 

 example of Anodonta cygnea var. incrassata Sheppard. 



For the Mycological Section, the Hon. Secretary (Mr. C. 

 Crossland, F.L.S.) reports : — ^The results achieved by the 

 Fungus Section came quite up to expectation. The long spell 

 of hot, dry weather had warned us not to be over sanguine in 

 regard to quantity. The few toadstools met with are of 

 common occurrence, with the exception of Mycena pullata and 

 Heheloma snhsaponaceuni Karst. The latter does not appear to 

 have been previously recorded for Britain ; H. sinapi-zans and 

 H. crustidijiiforme are its two nearest allies ; it differs from the 

 former in the non-emarginate gills, and in smell ; from the latter 

 in the dry, non-crenulate, adnate gills, and the strong, soap- 

 like smell. Next in point of numbers come the Uredinaceas.
