Hornsea : Its Mere and Coastline. 



Mycology. — Mr. C. Crossland writes: — The three 

 mycologists — R. H. Phihp, W. Robinson, and the writer, 

 spent their time around the margin of the mere. There 

 was any quantity of material to be found on the dead 

 stems of Phragniites couiiiiiinis, Epilohium hirsuhini, a.nd 

 other deca3'ing vegetation. Members connected with other 

 sections brought in several interesting agarics, among them 

 being PhoUcta dura (Bolton) and P. radicosa (Bull.). The 

 latter, with its rooting stem and strong smell was found on a 

 decaying stump. Some of the micro-material still remains 

 undetermined, but we are hoping to get through it before long. 

 Of the species determined, represented by the following list, two 

 are new to Britain, four new to the county, and thirteen new to 

 vice-county, vS.E. These are respectively noted by the signs 

 *, J, T. In addition to the four new Yorkshire species, there is 

 Periconia pycnospora, but this was first found in the county at 

 the recent Brafferton Excursion ; it was not included in the 

 Brafferton list, as it vv'as not then definitely determined. The 

 new British discomycete — Tapesia retincoIa~\v2iS fairly abun- 

 dant on dead stems of Phragniites. Heptameria graminis also 

 on Phragmites, has been only once previously recorded for the 

 county — ' Grev.,' XVHI (i8go), p. 59 for Terrington, but this 

 record was accidentally overlooked when the ' Yorks. Fung. 

 Flo.' was compiled. The finding of the iEcidium of Puccinia 

 orchideanim — phalaridis Kleb. on Listera ovata is also worthy 

 of special note, as it appears to be the first time it has been 

 noticed on this particular host in Britain.
