Ecology and Phenology of Surrey Mycetozoa. 59 



part of the year in a confined space, namely, the wonderful 

 grounds of St George's College, Weybridge, kno\\Ti locally as 

 Wobum Park. Here, in an area of just under a hundred acres, no 

 less than 90 different species and iS varieties have been recorded*. 



There have been many notable forerunners in the same field. 

 I have no knowledge of the extent of the work of Messrs Massee 

 and PhiUips, but no doubt many of their specimens were 

 obtained in this coimty. The late Mr Arthur Lister, his daughter 

 Miss G. Lister — the chief authority on the subject to-day — 

 her sister Mrs Phear, and the latter's sister-in-law Miss Margaret 

 Phear, have also made many notable finds especially in the 

 south-west of the countv; Mr E. S. Salmon has furnished useful 

 records of the Reigate neighbourhood, and Miss A. Hibbert- 

 Ware and Prof. Farmer have also been successful hunters in 

 Surrey: so that we now have the record number of 12S species 

 and 19 varieties, or two-thirds of the kno\Mi British species. 



The present list is of particular interest as it includes one 

 species new to Europe: Didymiuyn anomalum; one new to 

 Britain: Trichia alpina; two new to England: Physarum glohidi- 

 feriim and Ph. crateriforme; Miss Lister's recently published 

 species: Didymium trachysporum ; and nearly thirty new to 

 Surrey. 



I gladly take this opportimity of expressing my grateful 

 thanks to Miss G. Lister, F.L.S., for all her help in examining 

 my finds and checking my results, and for the valuable informa- 

 tion and directions contained in her various writings which have 

 been my guide throughout. 



My experience has taught me that much precious time may 

 be lost by looking for specimens at times of the year when 

 they are not hkely to be found, or in situations where they have 

 never yet been met with. It thus occurred to me that records 

 of dates and habitats would be a useful — though not infalhble — 

 guide to others who find their pleasiure in hke pursuitsj. 



1. Ceratiomyxa fruticulosa Macbr. is very frequent from May 

 to October on rotting Ume, alder, birch and pine wood and 

 appeared oozing out of the ground in great masses of shme in 

 October, on a pathway thick with old pine sawdust at Wey- 

 bridge. 



2. Badhamia capsulifera Berk, appears in late autumn every 

 year and has been found in November on fir, oak, alder and 

 lime branches; in the last case the plasmodium was feeding 

 on Exidia glandulosa. 



* Any mycologist wishing to hunt over the same ground will always be ver\' 

 welcome. 



t Those species marked with an asterisk were first recorded for Surrey- by 

 the writer, those marked f were first found by Miss G. Lister, F.L.S.
