CORTINARIUS. 6 1 



Among moss in woods. Glamis, 1875. Sept. Hygrocybe. 



Name — detondeo, to shear. Shaven, smooth. Fr. Monogr. ii. p. no. 

 Hym. Eur. p. 397. B. & Br. n. 1552. S. Alycol. Scot. n. 503. 



126. C. obtusus Fr.— Pileus 1-4 cent. 04.-1%. in.) broad, at 

 the first bay-browu-ferruginous, soon cinnamon, when dry either 

 (according to age) becoming pale-ochraceous or tan -whitish, 

 somewhat membranaceous, conical then campanulate, at length 

 expanded and obtusely umbonate, smooth, striate at the margin. 

 Stem 5-10 cent. (2-4 in.) long, at first spongy-stuffed, soon hollow, 

 comparatively thick, curved, flexuous (not undulated), attenuated 

 at the base, fragile, sprinkled with adpressed white silky fibrils, 

 otherwise rather smooth, tan-yellowish when moist, whitish when 

 dry. Gills adnate, ventricose, somewhat distant, very broad, 

 rather thick, the shorter ones narrower, connected by veins, 

 tawny-cinnamon, white-fringed at the edge. 



Spores somewhat ochraceous. Gregarious. Strong-smelling. Cortina 

 entirely fibrillose, whitish ; pileus when young here and there rendered hoary 

 silky by the cortina, commonly smooth, but torn when dry. Umbo vanishing. 

 It is very changeable in stature, but the colour is constant, though it changes 

 so much with age and the state of the atmosphere that it requires long 

 familiarity with the plant to enable one to distinguish individual specimens in 

 different conditions. 



In woods, chiefly pine. Frequent. Oct. 



Name — obtusus, obtuse. From the umbo. Fr. Monogr. ii. p. in. Hym. 

 Eur. p. 397. Icon. t. 163./. 3. B. & Br. n. 1274. S. Mycol. Scot. n. 504. 



127. C. acutus Fr. — Pileus honey-colour to very pale yellow 

 and somewhat shining, tan or white when dry, with a silky 

 appearance, somewhat membra7iaceous, conical then campanulate, 

 then expanded, umbo acute and of the same colour, at length 

 depressed round the umbo, striate when moist, obsoletely fibril- 

 lose round the margin when young, smooth when full grown ; 

 flesh very thin, of the same colour. Stem 7.5 cent. (3 in.) and 

 more long, 2-4 mm. (1-2 lin.) thick, fistulose, slender, equal, 

 flexuous, white-fibrillose, at length smooth, of the same colours as 

 the pileus when moist and dry. Cortina adhering to the margin, 

 fibrillose, white. Gills adnate, thin, crowded, more distant as the 

 pileus becomes more expanded and sometimes free, lanceolate, 

 ochraceous-cinnamon. 



Sometimes scattered, sometimes growing in troops. The habit is that of 

 Galera, but remarkable for its acute umbo.

Spores ellipsoid-oblong, nucleate, 8-9x3-4 mk. C.B.P. Name— acutus, 

 acute. From the umbo. Fr. Monogr. ii. p. 112. Hym. Eur. p. 398. Berk.
