a true representation of the original, then it may still happen 

 that our species is that given by Cooke, but until this is 

 settled we leave it under T. colossa. The following is the 

 description of our specimens: — Caespitose. Pileus 3 inches 

 in diameter, convex, brownish-tan, somewhat squamulose and 

 cracking, edge turned in when young. Gills crowded, straw- 

 coloured, becoming discoloured rufous, adnate. Stem stout, 

 2^ inches x 1^ inch thick, somewhat bulbous, discoloured 

 reddish-brown, white above. Flesh showing pink at the base 

 of the stem and under the. cap. Spores pear-shaped, white, 

 7x5-2 /x. Newcastle (Miss Clarke), April, 1915. Other 

 specimens show a cap convex to plane, and finally often up- 

 turned, up to 4 J inches in diameter, shining, fawn to reddish- 

 brown, when old often very dark reddish-brown and slimy, 

 broken up more or less into scales ; flesh thick ; gills adnate 

 or sinuately adnexed, spores 5'5 to 6*8 x 3'8 to 4'2 n, in some 

 specimens apparently of this species 7 to 8'5 x 5'2 to 7 /x.

Clitocybe. 



sect. i. disciformes. 



96. Clitocybe media, Peck. — Peck's description (N. York 

 State Mus., Mus. Bull. 157, p. 61) is as follows: — "Pileus 

 fleshy, convex, becoming plane or slightly depressed in the 

 centre, often wavy or irregular on the margin, not polished, 

 greyish-brown or blackish-brown, flesh white, taste mild ; 

 lamellae broad, subdistant, adnate or decurrent, whitish, the 

 interspaces often venose; stem equal or nearly so, solid, elastic, 

 coloured like or a little paler than the pileus; spores ellip- 

 soid, 8x5 /a.. Pileus 5 to 19 cm. broad; stem 2"5 to 5 cm. 

 long, 8 to 16 mm. thick. Gregarious or scattered. Mossy 

 ground in woods." 



We have not had access to his plates of the species. The 

 following South Australian plants approximate to the descrip- 

 tion of C. media, though differing in some details, e.g., the 

 pallid-whitish stem. They differ from C. nebularis, Batsch, 

 in their larger spores, and from C. cl art pes, Pers., in the 

 non-clavate stem and non-decurrent gills. There seems justi- 

 fication for the present in placing them under C. media. 



Pileus up to 6 inches across, convex, then plane or a 

 little upturned, somewhat irregular and wavy, subgibbous, 

 matt, centre smoky-brown, the rest moist -looking yellowish- 

 stony-brown. Flesh whitish, moist-looking in places. Gills 

 adnate, close', whitish, then rather pallid or creamy. Stem 

 up to If inch high, slender to stout (-ud to f inch thick), 

 rather attenuated in the middle, slightly fibrillose or fibrously
