,a bevy of Leptomeris immutata, L., in the afternoon ; and there at dusk saw Ophiusa pastinum, Tr., further L. immutata, many Phragmatobia fuliginosa, L., Nudaria senex, Hb., and, careeringover Reeds, numerous Leucania impura, Hb. I returned home the following day with a bag of over eighty Macro-lepidoptera ; and must express my indebtedness to Mr. Burton for introducing me to new and interesting localities containing several choice and loeal species. 20 August 1946.
THE ASCOMYCETES OF SUFFOLK. BY ARTHUR MAYFIELD,
F.L.S.
THE Ascomycetes are a large and important group of Fungi, distinguished by producing their spores within globular or clubshaped cells, called Asci. In most cases the ascospores number eight in each ascus. Some of the. species, such as the Morels and Cup Fungi, attain a fair size but the majority are very minute. T h e Ascomycetes are divided into two sub-groups :—(a) T h e PYRENOMYCETES, whose asci are developed inside a spherical or flask-shaped Perithecium which, when mature, opens to relcase the ascospores ; and (ß) T h e DISCOMYCETES, in which the asci are produced on the surface of a disc-like or cup-shaped fructification called an Apothecium.—Many of the more conspicuous species are recorded in Henslow and Skepper's ' Flora of Suffolk ' ; and several of these were re-published, with additional localities, by the late Revd. E. N. Bloomfield in Trans. Norfolk & Norwich Naturalists' Soc., vol. viii, pp. 263-4 [1906 ; & Vict. Hist. Suffolk 1911, i, 84.—Ed.]. Quotations from these sources are here indicated by the initials (H. & S.) and (ENB) respectively. T h e records initialled (EAE) were kindly sent to me by Mr. Edward A. Ellis of Norwich Castle Museum ; and to him and Mr. Ronald Burn, who also gave me some interesting specimens, I tender my sincere thanks. My own gatherings were made chiefly in Mendlesham ; and it should be understood that, in every case where no locality is assigned, the fungus was found in that parish. Of the 438 species here listed, 312 have not hitherto been recorded from Suffolk. PYRENOMYCETES. GYMNOASCALES.
