WHITE-SPORED AGARICACEAE. 



Amanitopsis. 



253. Amanitopsis suhvaginatus, n. sp. — Pileus up to \\ inch in diameter, 

 convex, "Ashy-Grey" (Dauthenay, pi. 358, Ton 3), mealy, edge striate. Gills 

 just reaching the stem, close, white, edge finely serrate. Stem, I-2- inch long, 

 moderately stout, mealy white, solid, base a little bulbous. Volva marginate, 

 colour of pileus. Spores spherical, with a small pedicle, 7 5 to 9 /x.. On the 

 ground, usually in subclayey pockets in the Hawkesbury sandstone by the sides 

 of paths. Cremorne Point and Bradley Head, Sydney liarbour, March, April, 

 November, December (Miss Clarke, Watercolour No. 171). 



Pileus ad 32 cm. latus, convexus, subcineraceus, farinaceus, margine striato. 

 Lamellae ad stipem assecutae, confertae, albae, marginibus subserratis. 

 Stipes ad 39 cm. altus, subrobustus, farinaceus, albus, solidus, ad basem 

 sub-bulbosus. Volva marginata, subcineraceus. Sporae subsphaericae, 

 7-5-9 fx. (PI. i., fig. 6.) 



Mycena, 



254. Mycena epipterygia, Scop. — We refer the following to this species, 

 though our plants are smaller and we have no note of a decurrent tooth to the 

 gills. Pileus and stem glutinous, and both when young in colour near Sulphine- 

 Yellow (Ridgway, pi. iv.), the pileus later near Dark Olive-Bufif (pi. xl.). 

 Pileus f inch high, five-sixteenth inch in diameter, at first ovate conical, then 

 conico-campanulate, gibbous, apex darker, periphery paler, rugose. Gills 

 ascending, adnate, rather ventricose, moderately close, white. Stem up to 

 3 inches high, slender, hollow, a little strigose below. Spores 8x4-8 fi; no 

 cystidia seen. Attached to buried sticks, etc.. Mount Lofty, S.A., June (Miss 

 Fiveash, Watercolour No. 13). (PI. ii., fig. 3.) 



Marasmius. 



255. Marasmius siibinstitius, n. sp. — The following seems allied to M. 

 institius, differing in the absence of umbilication, in the dark stem, and in the 

 presence of cystidia. Pileus ^ inch in diameter, convex, occasionally reaching 

 J inch when more expanded, slightly coarsely rugose, pallid brownish, surface 

 matt. Gills adnate, distant, relatively few, alternate ones short, deep, colour of 

 pileus. Stem up to l:g: inch high, blackish, like horsehair, finely villous, abruptly 

 leaving the matrix. Spores elongated, one end more pointed, 8-5 x 2-8 fx; a 

 few thick-walled cystidia with rough apices, 52 to 60 x 12 fi. On dead leaves, 

 sticks, etc., Mosman, Sydney, May, 1919 (Miss Clarke, Watercolour No. 205). 

 (PI. i., fig. 5.) 



Pileus 3-6-2 mm. latus, convexus, subrugosus, pallido-subfuscus. Lamellae 

 adnatae, distantes, subpaucae, pallido-subfuscae. Stipes ad 3-2 cm. altus, 

 subniger, similis equino-crini, villosus. Sporae elongate, 85x28 /j.; cystidia 

 apicibus asperis. 



256. Marasmius rugoso-elcgans, n. sp. — We refer the following to a new 

 species. Pileus 7 to f inch broad, \ inch high, at first rather conico-hemispherical, 

 then hemispherical or rather bell-shaped, slightly gibbous, coarsely rugose, surface 

 matt, edge turned in when young, near Brownish-Terra-cotta (Dauthenay, pi. 

 322, Ton 4), the ridges darker, brittle. Gills adnate, attached to a more or less 

 definite collar, distant, often short, about 15 in number, white to cream or 

 pinkish-white. Stem ^ to 2 inches or more long, hair-like, dark brown or Purple- 

 black (Dauthenay, pi. 345, Ton 3) except pallid to whitish just below the pileus, 

 smooth, abruptly piercing the matrix or (in the Dorrigo specimens) with a pad 

 of fluffy white mycelium at the base, the fallen leaves, twigs, etc., forming the 

 substratum on which it grows being covered with a pallid whitish or greyish
