LEUCOSPORI. 49 



margin remaining deflexed and incurved ; always very dry, at the very first Tricholoma. 

 minutely and very densely granulated, but the granules are wholly innate, 

 having originated from the cuticle being broken up ; granules at the first so 

 continuous that the pileus is black ; when full grown, however, the granules are 

 so distinct, on account of the small cracks, that the white ground shines through 

 between myriads of them, wherefore the pileus appears as very densely 

 black-dotted. No distinct odour. Formerly confounded with a form of A. 

 saponaceus.

89. A. loricatus Fr. Pileus 2.5-5 cent - 0~ 2 m -) broad, some- 

 times umber, sometimes livid-fuscous, paler round the margin, 

 slightly fleshy, lax, campanidate then convex, most frequently 

 undulated, even sinuato-lobed, moist (slightly viscid), smooth, 

 punctato-rugulose iinder a lens, clothed as in a cuirass with a thick 

 horny separate cuticle; flesh peculiar, scissile. Stem 5-7.5 cent. 

 (2-3 in.) long, about 6 mm. (3 lin.) thick, fleshy-fibrous, but very 

 tough, somewhat hollow, twisted, irregular, equal or attenuated 

 downwards, rooted, brick-fuscous, fibrilloso-striate under a lens. 

 Gills quite free and separable from the hymenophore, very 

 crowded, ventricose, quite entire, whitish-straw colour. 



The upper cuticle is 2 mm. (i lin.) thick, somewhat horny, fuscous, wholly 

 different from the pith of the stem, which (pith) enters at the centre between 

 the cuticle and the hymenophore which is continuous with the stem. Odour 

 strong, not pleasant, but not soapy. 



In mixed woods. Glamis, 1875. Sept. 



The flesh of the pileus is simply a prolongation and expansion of the pith of 

 the stem between the horny cuticle and the hymenophore. Name lorica, a 

 leather cuirass. Fr. ^lonogr. i. p. 71. Hym. Eur. p. 60. Icon. t. 35. f. 2.

 smooth, dry, opaque, at first even and entire, at length rimosely 

 incised and revolute at the margin, but not broken up into scales. 

 Stem 5-7.5 cent. (2-3 in.) long, 8 mm. (4 lin.) thick, stuffed, in- 

 ternally soft and when moist hyaline, equal, cylindrical, slightly 

 striate with longitudinally adpressed fibrils, and naked at the apex,

 current with a tooth or arcuato-adnexed, more or less ventricose t 

 thin, crowded, hyaline-white.
