AN OLD SUFFOLK NATURALIST

Torquay. At one time he trawled Coelenterata Jel'yfish off Harwich (Vict. Hist. 1911, 89) & he collected Mollusca, mainly pliocene specimens from the Red Crag of Felixtow. Unfortunately I am unaware that he ever published anything relating to Natural Science.

SMUT-FUNGI. F.L.S.

THE Hyphomycetes are imperfect fungi, being for the most part the conidial stages of the Ascomycetes. They bear their spores on septate hyphaj, exterior to the host-plants and not in pycnidia or pustules as in the Ccelomycetes (see Trans., vol. iv, p. 101). The Phycomycetes are parasitic or saprophytic moulds with nonseptate mycelium. They are remarkable for being the group of fungi in which sexual fertilisation was earßest recognised. Several of the species are the cause of diseases destructive to garden crops. T h e Ustilaginales are parasitic in the tissues of flowering plants, especially those of cereals and other grasses, producing the masses of dark-coloured spores which form the well-known ' s m u t ' of wheat, oats, etc.—For their determination I have tapped (1) M C. Cooke's 1871 Handbook of British Fungi, and (2) 1878 Microscopic F u n g i ; (3) G. Massee's 1893-5 British Fungus Flora ; (4) E. M. Wakefield & G. R. Bisby's 1941 List of Hyphomycetes Recorded for Britain, in Trans. Brit. Myc. Soc., vol. xxv ; &c. Except where otherwise indicated, the fungi listed hereunder were collected in the parish of Mendlesham. A few localities (initialled H. & S.) have been quoted from Henslow and Skepper's ' Flora of Suffolk ' 1860, and I have again gratefully to acknowledge the valuable assistance of Messrs. E. A. Elbs (E.A.E.) and R Burn. The following list of 245 species, of which 203 are NEW records for Suffolk, is far from being exhaustive ; further research will undoubtedly reveal many other species, especially of the Phycomycetes.
