65. // ypholoma sublateritium, Schaeff. : t. 49; Cooke: 

 Illustrs., pi. 557; Massee : Brit. Fung. Flora, i., p. 380. — 

 The following plants, collected on a fallen log at Mount 

 Wilson, Blue Mountains, in June, 1915, seem to belong to 

 this species rather than to //. fasciculare : — Pileus 2J inches 

 in diameter, orange-brown, yellowish towards the edge, con- 

 vex, then expanded. Gills dirty yellowish-green, sinuate. 

 Stem up to 4 inches long, markedly attenuated downwards, 

 white above, then stained reddish-brown, shining, slightly 

 striate, hollow. Caespitose. Bitter. Spores purplish, 6 to 

 8'5 x 3*8 to 4'2 jtx. No cystidia seen.

 E. T. Harper quotes Peck's original description as follows: — 

 "Pileus convex or nearly plane, sometimes umbonate, 

 glabrous, reddish or brownish-red, usually yellowish on the 

 maroin. Flesh white or whitish. Taste mild. Lamellae 



o 



thin, close, slightly rounded behind, adnexed, pale yellow 

 becoming tinged with green, finally purplish-brown. Stem 

 rather slender, equal or nearly so, firm, hollow, slightly 

 fibrillose, whitish or yellowish above, reddish-brown below. 

 Spores 3 to 4 x 6 to 8 u,. Pileus, 2*5 to 7 cm. broad. Stem 

 5 to 7 cm. long, 4 to 8 mm. thick. Generally caespitose. 

 On or about stumps or prostrate trunks of trees in woods 

 or open places. Edible." Harper adds that Peck says that it 

 differs from Hypholoma sublateritium in its "smaller size T 

 paler margin of the pileus, somewhat umbonate pileus, mild 

 taste, and paler and more slender stem, which is always, 

 hollow, even when young." Harper also states that this plant 

 has usually been considered a form of H. sublateritium . From 

 the descriptions Harper gives, it would appear that the gills 

 in H. perplexuui are "slightly rounded behind, adnexed," 

 whilst in //. sublateritium they are "adnate." 



The following, collected at Mount Wilson, Blue Moun- 

 tains, in June, 1915, seems to belong to this species: — Pileus 

 2 inches . in diameter, convex, dark tanny-brown^ slightly 

 gibbous. Gills rather sinuately adnexed, moderately close, 

 brown with a greenish tinge. Stem brownish, white mealy 

 fibrils below, base a little swollen, slightly hollow. Flesh 

 yellow. Taste mild. Densely caespitose on a fallen log. 

 Spores purplish-brown, 7 to 7'6 x 3"4 to 4'2 /x. No cystidia 

 seen . 



67. Hypholoma fragile, Peck: N. York State Mus., 

 Mus. Bull.; 131, 1909, p. 22 (pi. v., figs. 1-7).— This species 

 has given us considerable trouble. Though closely resembling 

 the descriptions of II. append 'iculatum and H. candoll eanum , 

 it did not seem to be either. Miss E. M. Wakefield, of Kew,
