FORMATION of perithecia of the oak mildew is a rare occurrence in Britain, the only record known to me being that of Robertson and Macfarlane1, who found one leaf with six perithecia at Bricket Wood, Hertfordshire, on October 6, 1945. It is therefore of some interest to note that a few perithecia were found on leaves of Quercus robur at Aberystwyth on October 2, 1947. The identification of the fungus as Microsphœra alphitoides Griff, and Maubl. was kindly made by Mr. S. J. Hughes, Imperial Mycological Institute, who compared the Aberystwyth material with a slide of Robertson and Macfarlane's specimen deposited in the Herbarium of the Royal Botanic Gardens, Kew. |
