Mycology Report, 1963 By D. Boardman The wet summer of 1963 produced ideal conditions and fungi appeared in quantity during July and continued well into Novem- ber, giving us an unusually long period for recording work which has made good progress this year. Earthstars (Geaster bryantii) turned up again in Chingford and Woodford Green and a new station was reported from Purleigh. In the spring, Morels (Morchella esculenta) were re- ported from High Beach and Chelmsford, a new record for the county. The annual foray was held in the Ingatestone area, and Mill Green woods produced some interesting records. Eighty-seven species were recorded. Tree fungi were very plentiful and the genera Lactarius and Russula, were well represented. It was pleasing to find several species of Hygrophorus, so frequently absent on our forest forays. The highlight was in finding eleven species of Cortinarius, many of them new records. Our grateful thanks are due to Mr. J. B. Evans of the British Museum (Natural History) who kindly identified these and other critical species found during the season. The year's climax was undoubtedly the recorder's meeting held on 12th October in the Baldwin's Hill area of Epping Forest with Mr. R. W. Rayner and Mr. C. Jeffrey of Kew. With their expert and willing help we managed to record 98 species and varieties. Concentrating mainly on Russula and Lactarius we recorded some additions to Pearson's list and re-recorded several species not found since 1938. With the publication this year of the long-awaited Collins' Guide to Mushrooms and Toadstools, it is now possible for all students of mycology to own an adequate text-book, and this excellent work by Dr. Hora and Morten Lange should make field identification easier especially as chemical tests are included as well as field characters. The book uses the new system of nomenclature which is now generally adopted and it would appear that the time has now come for us to turn over to the new system for our records. I am now actively engaged in re-organising the card index records of some 1,000 species and renaming these
