NEW AND RARE BRITISH FUNGI.
By Carleton Rea, B.C.L., M.A, 6c. With Plates 14,*1 5 and 16. Psaliota Bernardii QuCl. Soc. Bot. XXV. t. 3, f. 12. F1. Myc. 73 and see plate 14. Pileus 10-20 cm. wide, convex then expanded, lirm, the tomentose surface of the pileus soon breaking up into thick, angular warts, white then turning ferruginous at the apex of the warts. Stem 6-7cm. long, 4-5cm. thick, bulbous at the base, attenuated upwards, solid, stuffed with delicate threads, striate at the apex, white becoming reddish brown with age. Ring membranaceous, soon disappearing, striate on the upper surface. Gills 8-12mm. wide, free, attenuated at both ends, greyish flesh colour, finally blackish purple. Flesh firm, white then tinged with purple and finally stained with reddish brown. Smell unpZeasant. Taste disagreeable. Spores blackish purple, ovoid elliptical, 9-11 x 6 - t p , one guttulate with an apical germ pore. Amongst short grass, fifty yards from the edge of the cliffs near the sea, Bettyhill, Sutherlandshire, Miss Alice Warrender, I st October, 1910. Our member Monsieur RenC Maire, D.Sc.. kindly confirmed my determination of this plant and told me that he had found it ih many places near to the sea, In France near the mouth of the Loire, In Algeria at L a Lenia, near Oran, and on the border of the high lands of Chott and Chergui, In Greece at Argos and in Hungary on the Putza Hortebagy. This very distinct Mushroom is easily recognized by the surface of the pileus breaking up into areolated warts and by its disagreeable smell. Psaliota exserta Viv. Fr. Hym. Eur. 280 and see plate I 5. Pileus 6-18cm. wide, fleshy, campanulate then convexo-expanded, white becoming yellowish ochraceous and broken up into minute adpressed scales. Stem 10-15 cm. long, 3-6 cm. thick, stuffed, either slightly attenuated upwards from the base or ventricose at the middle, white, bleeding when cat or wounded, almost smooth. Ring large, membranaceous, thick, double, made up of two layers that split apart, white, covered on the underside with yellowish, fugacious warts. Gills 5-10 mm. wide, free, somewhat crowded, whitish then pinkish and finally fuscous. Flesh quickly turning bright red when bruised or Thc Rev. W. L. W. Eyre, has most generously presented the Society with this plate.
cut or woanded and exuding a bright red juice which finally stains the part affected deep brown. Smell and taste pleasant. Edible. Spores subglobose, 5-6 x 4-5p, one guttulate with an apical germ pore, deep ochre when deposited in the mass. Solitary or in rings amongst rank grass, pastures near Inchbrook, Gloucestershire, Mr. Basil P. Marmont, 6th November, 1908. This species is characterized by its double ring, deep ochre subglobose small spores and the bright blood-coloured juice which it exudes when cut or wounded. Psaliota flavescens Roze. QuCI. F1. Myc., 73, pro parte., Gillet Ch. de Fr. 129 and see plate 16. Pileus <-12 cm. wide. cam~anulatethen ex~anded.smooth. dry, shining with a satin-lirke sheen, white, at once turning saffron colour then finally light brown when touched or bruised, pellicle easily separable. Stem 10-14 cm. long, 1'5-2 cm. thick, cylindrical, long in proportion to the dimensions of the pileus, stuffed with a few loose threads when young, soon hollow, white with a satiny sheen, tinged reddish yellow at the base on one side. Ring membranaceous, soon disappearing, dirty white, yellow on the outside and more deeply coloured at the margin. Gills 5-12 mm. wide, free, crowded, pale pink then pink and finally brownish. Flesh white, turning instantly bright saffron yellow when fresh and reddish yellow when drier, especially near the surface of the pileus and at the base of the stem. Smell none. Taste not disagreeable. Spores oval, 5-6 x 4 - 5 ~ , reddish brown, one guttulate with an apical germ pore. Solitary or in clusters and rings, in open upland pastures, near Inchbrook, Gloucestershire, Mr. Basil P. Marmont, 6th November I 908. Above Ribbesford, Worcestershire, October, 1909, C. R. Easily known by its long white satiny stem and pileus, which instantly turn bright saffron yellow at the slightest touch or when bruised. This species is very poisonous to many people. QuClet seems to have included in his definition of P. flavescens some characters that are attributable solely to P. xanthoderma Genev. This latter species is characterized from the former by its offensive smell, shorter and broader stem, and pear-shaped reddish brown spores 6 x 4p. 4
Androsaceus epip/tylloides Rea. See plate I q.* Pileus 2-5 mm. wide, membranaceous, somewhat spherical i t first, then convex and expanded, tomentose, white. Stem 3-8 Pileus 2-5 mm. latus, membranaceus, e ronveuo-subhemisphaerio expansus, totnentosus, albus. Stipes 3-8 mm. longus, .CJ mm. crassus, e farcto fistulosus, aequalis, velutinus, spadiceus apice albus. Lamellae albae, adnatae, '5-1 mm. latae, interdum venoso-conjunctae, distantes, paucae. Sporae albae, Cystidia cuspihyalinae, elongato-clavatae, 13-15x 3.5-4p, multiguttulatae. data, basi ventricosa. 43-45 x 9-10s Hab. ad folia eusiccata Hederac Helicis.
mm. long, '5 mm. thick, stuffed then hollow, equal, velvety, chestnut brown, white at the apex. Gills white, adnate, '5-1 mm. wide, sometimes connected by veins, distant, few. Spores white, hyaline, club shaped, I 3- I 5 x 3'5-4p, multiguttulate. Cystidia 43-45 x 9 - I O ~attenuated , at the apex, ventricose a t the base. On dead Ivy leaves, Swarraton, Hants, November and December, 1909and I 910,Rev. W. L. W. Eyre. The tomentum on the surface of the pileus consists of two forms of cystidia, the one 30-jb x 4 - ~ p ,the other short, toothed at the apex on the margin and from 8-12p wide. Easily distinguished from Androsaceus epiphyZZus (Fr.) Pat. by the tomentose pileus and long club-shaped spores. Fomcs laccatus (Kalchbr.) Sacc. Syll. XI., 89 (=Polyporzrs Kalchbr. & Wettst. Bot. Leitschr. (1885) 81. Pileus very hard, convex, dimidiate, sessile, horizontal, concentrically sulcate, irregularly tubercular, glabrous, crustaceous, copper colour, rarely fuscous when old, very shining and varnished, flesh very densely fibrillose, pliant, margin sterile, entire, very shining, reddish. Pores thin, orifice very small, round and deep ochraceous. Spores hyaline, subglobose. Habitat. On living trunks of Cherry in Lower Austria. Pileus I 0-20 cm. across ; spores 3-5 x 2-4p. Our member, Mr. C. G . Lloyd, of Cincinnati, informs me that he found this species fairly common in England in 1910. It is characterized by the strongly laccate surface of the pileus, similar to that found on Fomes lucidas Fr., the deeply coloured, compact, hard flesh and the small hyaline spores. Fonzes resinaceus (Boud.) Rea (= Ganoderma Boud. in litt. ; G. ajplanatus Fr. Hym. Eur. 557 et Auct. plurr. Patouillard Bull. Soc. Myc. Fr. v. 72. Large, r 5-30 cm. wide, perennial? Pileus semicircular, somewhat flattened, sessile, rarely stalked or imbricate, concentrically sulcate, the primary furrows wide, becoming shallower and more crowded with age, covered with a varnished yellow, then blood red umber chestnut crust which is at first very shining, then duller and dusted with the spores ; margin at first white, delicately pruinose and rounded, becoming glabrous, more acute and concolorous. Pores minute, rounded, elongate, and finally stratose, when they measure about 3 cm. in length, orifice a t first white then fuscous cinnamon. Spores ovate oblong or obovate, truncate at the base, fuscous, quite smooth, epispore thick, eguttulate or one guttulate, 10-I 2 x 6-7p. Common, on trunks of Oak in old woods near Blois, Central France.
This species is easily distinguished from G. applanatum by its very soft consistency, smooth spores and frequent viscid surface. It differs from G. australe in its thick flesh and from its ally G. carnosum in the margin which is never hard and horny and its smooth not verrucose spores. It very closely resembles G. lucidum and has often been considered a sessile form of that species, but it is distinguished by its sessile growth on the trunk of the tree itself (only very rarely having a rudimentary stem), its larger size, greater thickness, softer flesh, which is more fibrous and less fine, and especially by its tubes, which are sometimes stratose, and its quite smooth spores. On Beech, Oak, Pinus halepensis, &c., near Paris, Nantes, Marseilles, Tyrol, &c. On Beech, Kyre Park, Worcestershire, 24th September, 1910, and on Oak, Wynnstay Park, 30th September, 1910, C. R. It is easily distinguished from F. applanatus by the more viscid, laccate surface of the pileus and lighter coloured flesh. My thanks for its determination are due to Mr. C. G. Lloyd and L'AbbC G. Bresadola PAZebia albidn Fr. hlonogr. 11. 280. Hym. Eur. 625. White. Spots orbicular becoming confluent, adnate except at the margin which is definite, waxy coriaceous when moist, cartilaginous when dry. Hymenium consisting of simple, elevated wrinkles irregularly dispersed over the surface. Spores white, hyaline, elliptical, obtuse at both ends, 4-5 x z'5-3p, one to two-guttulate. On a fallen trunk, Stevenston Wood, Ayrsnire, Mr. D. A. Boyd, 4th October, 1910. This species is characterized by its pure white colour, simple wrinkles, and its Corticium like consistency which becomes cartilaginous when dry. Corticium atrovirens Fr. See Trans. Brit. Myc. Soc. vol. III., Pt. 3, 172. Through the kindness of Monsieur Rend Maire, D.Sc., we are able to give an illustration of this rare species with microscopic detail on plate 16. Dasj~scyphaflavo-fuligineum (A. Sr S.) Fckl. Rabh. Krypt. Flora I., 3, 888. Ascophores scattered or gregarious, 1-3 mm. wide, sessile, globose and closed at first then becoming plane with the margin slightly raised ; disc olivaceous brown or fuliginous, externally bright sulphur yellow densely villose, hairs simple, straight, obtuse, sparingly septate, almost smooth, yellow, colourless at
the ends 210-370 x 3-4p, asci cylindric clavate, rounded at the ~ apex, 7 ~ - 57 x 5-6p, 8-spored ; spores 9-1 I x 2 - 2 . 5 ~subcylindrical, hyaline, continuous, straight, obtuse; paraphyses lanceolate, acute, hyaline, 80-85 x 4-5p.

(1910) I 3;. nonnull. recent. non Thiimen Oidium qrcercinzlm var. gemmiparum Ferraris. Very densely tufted, effused, pulverulent, pure white or whitish, often confluent on the upper side of the leaf and sometimes entirely covering it, more attenuated on the under side ; sterile hyphae with globose haustoria, septate, hyaline, intricate ; conidiophores erect, septate ,SO-gox 5-gp, conidia ovate or jarshaped, obtuse at both ends, hyaline, guttulate 25-35 x 14-19p. On living leaves of Quercus. Bredon, Eesford, Wyre Forest, Tiddesley Wood and Nunnery Wood, Worcestershire. This species is very common and widely distributed, it is very easily recognized by its barrel-shaped conidia. Artlirobotrjls superbu Cda. Prachtfl., 43, pl. 21. Massee and Salmon. Ann. Bot. XVI.
