Var. Badense Schmidle, 1894. 



[Syn. C. sttbtholiforme var. Badense Schmidle]. 



Mid W. — Cocket Moss, near Giggleswick. 



N.E. — Pilmoor, near Thirsk. 



This plant is by no means an uncommon species in the boggy 

 districts of the British Isles. It is described and fairly well 

 figured by Schmidle in Flora oder allg. Botan. Zeitung, 1894, 

 heft 1, p, 58, t. vii., f. 21. We have figured its zygospore in 

 Journ. Roy. Micr. Soc, 1896, t. vii., f. 41, under the erroneous 

 name of C. confusum Cooke var. regidarms Nordst. The zygos- 

 pores were from the extensive bog on Thursley Common, Surrey, 

 and were not uncommon in a gathering made towards the end of 

 June, 1895. Schmidle, in Oesterr. Bot. Zeitschrift, Jahrg. 1895, 

 p. 21 (Sep.), remarks on its resemblance to C. confusum vax. regu- 

 larius and also to C. pramorsum Br^b. It certainly has some 

 resemblance to the latter species, but we think no one could fail 

 to readily discriminate between the two plants.
