Abstract
LONDON. British Mycological Society, March 17.—A. S. Home and H. S. Williamson: The morphological and physiological characteristics of two new species of Eidamia were described and compared with those of E. acremonioides, the only species previously included in the genus. One species obtained from oak wood is strongly acidophile and causes coloration of the wood; the other, isolated from decaying apples, is capable of causing rot in Bramley's seedling apple when kept under ordinary storage conditions or at a constant temperature of 1° C.—M. H. Carré and A. S. Home: Various fungi were grown in soluble pectin of a high degree of purity extracted from apples. Certain fungi utilise the pectin with production of acidity (Botrytis, Diplodia cacaoicola), others break it down completely with the production of sugar (Eidamia from apple), while some are apparently incapable of growth in pectin.—A. S. Horne and H. M. Judd: The Eidamia from apple grown in sugar solutions exhibits different reactions according to the sugar used, as evidenced by the odour (of coconut oil), liquid coloration, and rate of growth (on plates). The reactions appear to show a definite relation to the configuration of the sugars concerned.—H. S. Williamson: The species of Eidamia from oak caused the production of a yellow colour in seasoned wood. This colour was reproduced when normal oak was inoculated with conidia of the fungus, and was found to be partly due to the colour of the conidia and partly to a yellow refractive substance produced in the metabolism of the fungus and accumulated in some of the cells of the wood.—J. S. Bayliss Elliott and O. P. Stansfield: The life history of Polythrincium Trifolii. The Hyphomycete stage is followed by a pycnidial stage. After the pycnidial stage reaches maturity the clover leaves wither. It was found possible to obtain further development by placing the leaves between glass cover-slips placed between ivy leaves buried in soil in plant pots in the open. The perfect form is not a species of Phyllachora as has usually been supposed, but Dothidella.—J. Ramsbottom: The correspondence between M. J. Berkeley and C. E. Broome preserved in the National Herbarium covers a period of more than forty years, and gives a clear idea of the way in which the collaboration between the two was carried on. It contains a mass of biographical detail, particularly of Berkeley, and gives a much better picture of the “Father of British Mycology” than do the meagre and misleading biographies which have so far been published.—P. J. Alexander: The dates of appearance and habitats of the Mycetozoa of Surrey. No month is without a representative, and three-quarters of the British species have been recorded for the county.
