150 THE ESSEX FIELD CLUB. The "Scarlet Agaric" itself was in great profusion, forming brilliant patches under the birch-trees. In some of the meadows at Piercing Hill the common edible mushroom was very fine and plentiful, and some members secured ful' baskets. The remarkable "Parasol Mushroom" (Agaricus procerus) was also common in the same meadows as well as in the open forest. Some other very beautiful species were found, and the long tables at the farm soon looked very gay with the brightly coloured plants. It was a universal subject of regret that such beautiful natural objects could not be effectively preserved. Several cameras were on the ground, and Mr. Whitehead secured some very interesting photographs of "plant associations" for the collection at the Essex Museum. Mr. Wilfred M. Webb, F.L.S., also took many views, some of which we may hope to see in his forthcoming serial, The Country Home. The naturalists were gratified at re-discovering the little slug Limax tenellus which had been found in 1904 in Epping Forest by Mr. T. Petch, after having been lost as a British species for more than 50 years (see Essex Naturalist), It feeds on funguses, seeming rather to prefer the poisonous kinds. Truly a day of resurrections ! By the kindness of Mr. Gerald Buxton, the woods at Birch Hall were also visited by the members. At about five o'clock all the collecting parties returned to the farm, where Mrs. Morgan had prepared an excellent "high tea," and then a meeting was held, under the chairmanship of Mr. Miller Christy, F.L.S., the President. Mr. Massee gave a long but interesting address on "The Economic Aspect of Plant Diseases," dealing with the "life-histories" of some of the common injurious fungi or "moulds" which infest crops and gardens, explaining the wonderful advances made in the study at Kew and by continental botanists, discoveries which go far to modify or contradict all previous notions on the subject. It was evident from the facts brought forward that the persevering and careful study of fungi would result in discoveries of the highest importance to gardeners and farmers. Mr. Massee mentioned a case, in which he had been consulted this summer, of a rose tree fungus which had destroyed at least £500 worth of blossoming roses in a week. It was announced that an important meeting o( the club would be held about the middle of December to consider the pressing question of river pollution from the naturalist's point of view.
