ANNALES HISTORICO-NATURALES MUSEI NATIONALIS HUNGARICI Tomus 64. 1972. Hebeloma Studies I. By G. BoHTjs, Budapest Hebeloma ochroalbidum sp.n. (Fig. 1.) In poplar woods on a sandy substrate there grows a species resembling in habit Hebeloma crustidiniforme, whose characteristic features, besides its habitat, are as follows : Pileus whitish, in the centre pale ochre or entirely light ochre, smell mostly absent, taste mild. Pileus 5.5-10 cm in diam. ; convex-expanded; fleshy; whitish and in the centre pale ochre, entirely whitish ochre or light ochre ; smooth ; in wet weather viscid ; margin at first incurved. Gills to 5 mm wide ; at first pale, then more or less isabelochre, at length sordid brown ; edge under magnifying glass white setulose (ciliate) ; with watery drops in wet weather. Stipe 4-8 cm high, 1—2 cm wide ; cylindrical or with a thicker base; white; entirely but especially upwards fine floccose-grained ; firm. Flesh white, whitish ; chemical reactions : with guaiac tincture brown, with ammonia, formalin, guaiacol solution, iron sulphate, Lugol reagent, nitric acid, phenol-aniline, Pyramidon solution and sodium hydroxide negative. Taste not distinctive. Smell mostly absent or a little radish-like. Consumed in the neighbourhood of the village Fót (Comitat Pest), called "poplar mushroom". Spores 10.5-12.o-(14) X 5.5-7-(8.5) p,; almond-shaped, densely and conspicuously punctate, thick-walled, melleous. Basidia 4-spored clavate; 25—35 X 7-11 p.. Cheilocystidia crowded; clavate cylindrical sometimes subventricose, with a longer peduncle, hyaline, (45)-60-90 X (5)-7-9 p.. Spore print sordid brown. Pileus 5.5-10 cm in diam., convexus-deplanatus carnosus albidus in medio pallide ochraceus ex toto albido-ochraceus vél pallide ochraceus glaber pluviis diebus viscidus initio margine incurvatus. Lamellae usque ad 5 mm latae, initio pallidae, dein plus-minus isabellino-ochraceae, demum sordide brunneae, acie sub vitro optico manifeste albide ciliatae, pluviis diebus guttulis aquosis instructae. Stipes 4-8 cm alius, 1-2 cm crassus, cylindricus vel ad basin parum incrassatus, albus, ex toto, imprimis autem superius subtiliter floccidoso-furfuraceus, firmus. Caro albus, albidus, reactiones chemicae: per tincturam guajaci brunneus, per ammóniám, formaldehydum solutum, solutionem guajacoli, ferrum sulfuricum oxydatum, solutionem Lugol, acidum nitricum, phenol-anilinum, solutionem Pyramidon, natrium hydroxidatum immutatus. Sapor non distinctus. Odor plerumque absens, vel parum raphanaceus. Sporae 10.5-12.5-(14) x5.5-7-(8.5) p, amygdalae-formes, dense insigniterque punctatae, pariete crassae, melleae. Basidia tetraspora, clavata, 25-35 x 7—11 p. Cheilocystidia numerosa, clavata, cylindrica, nonnunquam subventricosa, peduncido longiusculo, hyalina, (45)-60-90x (5)-7-9 p. Sporae in cumulo sordide brunneae.
