NOTES ON KILLARNEY AGARICS By A. A. PEARSON LEPTONIA QUELETII Boudier, leones Myeol. PI.
100.
Pileus 1-3 em., convex, depressed in centre, submembranaceous but fairly firm, incurved at first, delicate violaceous pink, deeper in centre, pale round margin or fawn colour without trace of pink; minutely squamulose with a delicate sheen, flesh white, pink under cuticle. Gills subdistant, emarginate with a decurrent tooth, fairly broad, 2-3 mm., linear or ventricose, white then pink, edge straight or undulate. Stem 4-6 em. long, about 2 mm. thick, firm, hollow, white, minutely fibrillose, with white tomentose base. Basidia 4-spored. Spores in mass pink, nodulose, mostly with blunt angles and sharply pointed apiculus, 9-11 x 6'7 u, Cystidia none; cuticle of pileus of elongate hyphae 8-10 ft. wide, septate, hyaline, mixed with patches of coloured hyphae which give the pink tinge to the pileus. Taste mild. No smell. Habitat: in troops among grass and moss under trees. National Park, Muckross Demesne, Killarney, Ireland, 21 September 1936. Arthog, Merionethshire, Wales, 19 September 1937. Mr G. J. Cooke. PLEUROTUS CANDIDISSIMUS Berk. & Curtis in
Ann. Mag. Nat. Hist. (1859). Pileus 0'5-1 em., pure white, membranous, shell-like, finely pulverulent, slightly undulate, edge incurved. Gills white, crowded, thin. Stem rudimentary, the base of receptacle sometimes more or less elongated. Spores globose, 5-6 ft, apiculate, smooth, hyaline, with granular contents or 1-guttulate. Killarney, 24 September 1936. Specimens were brought in at the meeting of the British Mycological Society, and the above notes made by me. I was able to trace the species in the monograph of Pleurotus by Dr Albert Pilat (Prague, 1935). It closely resembles P. septicus and P. ehioneus from which it differs in the globose spores. As these small Pleuroti are often passed over, it may not be uncommon.
