THE FLATFORD MILL FORAY By F. B.

On Saturday, Stour Wood was searched, and Dodnash Wood on Sunday morning. Weather conditions during the Foray were dry and often bright and sunny-in fact, a continuation of conditions prevailing during preceding weeks. An abundance of material was not, therefore, to be expected.

THE FLATFORD MILL FORAY

By F. B. HORA, Foray Secretary

For this, the twenty-seventh Spring Foray, members were accommodatedat Flatford Mill and the adjoining Willy Lott's cottage, East BerghoIt,Suffolk, both well known for their association with John Constable, thepainter, whose father once owned the Mill. About twenty members werepresent.

On the first day (Thursday), a circular trip was made taking in HollesleyHeath, Shingle Street (on the coast) and Staverton Thicks. On Fridaymorning, by kind permission of Lady Wake Walker, we visited the woodson her estate. A lane divides these woods: that part on the side remotefrom the house is known as Commons Wood and on the near-side as TreeMeadows Wood. (Records in the List of Species are sometimes given interms of these divisions.) On the same afternoon, a party went to FishpondWood, which is close-by. On Saturday, Stour Wood was searched, andDodnash Wood on Sunday morning.

Weather conditions during the Foray were dry and often bright andsunny-in fact, a continuation of conditions prevailing during precedingweeks. An abundance of material was not, therefore, to be expected.This is the main cause of the shortness of the List of Species, but in additionit should be pointed out that some of the fungus groups lacked workerswho are specialists in those groups. Nevertheless, some interesting findswere made. Phellinus torulosus has only so far been recorded for the BritishIsles from Killarney on a dead stump of Arbutus unedo (these Transactions,35,35 (1953))' This tree is part of the Hiberno-Lusitanian group and it isinteresting to note that the Flatford gathering was from sweet chestnut,a naturalized but nevertheless introduced tree with an extensive southerdEuropean distribution like Arbutus. Mr Graddon was again very pleasento have a further locality for Sclerotinia hirtella which had turned up in somequantity at the previous Spring Foray. Coprinus lagopides was definitelyidentified. Carleton Rea did not claim to have found it, and described itas rare. It is probably quite common, but passed over in mistake forC. lagopus, from which it is at once separated by having subglobose sporesas distinct from elliptic ones.

Our warmest thanks are due to the Warden of Flatford Mill, Mr JohnBingley, and to his staff, for making our stay at the Mill so pleasant.

For help in preparing this report it is a pleasure to thank Dr AgnesBrown, Messrs Finney, Fletcher, Graddon, Parker-Rhodes, Reid andStenton.
