Of the Agarics: which may be gathered in Tas- 

 mania we have but a poor record. The reason is not 

 far to seek ; they are incapable of satisfactory preser- 

 vation. The softness of their structure causes such a 

 distortion in drying that means of critical comparison 

 are lost. Oertiainly they may be preserved in spirits or 

 formaline, but then the colour will go, and colour in 

 this group of plants is of first importance. The only 

 satisfactory way to proceed is to make a faithful water- 

 colour copy, also accu^rate notes of all features, and 

 trust that some expert may recognice and name them. 



The following four species may certainly be 

 added : — 



Collyhia protracta, Fr. Solitary, dark brown, 

 .almost black. Pileus to 5 cm., convex to plane, um- 

 bonate, smooth ; gills deep, dark gray often with a 

 lighter edge ; ste^m long, slender, solid fibrous. Spores 

 smooth, hyaline 9 x 6 /x. Distinguished by its black 

 ^colour, and very broad, crowded gills. 



Found occasionally in partially shaded places. 



'Collyhia hutyracea, Bull. Pileus convex to plane, 

 "smooth, rather hygrophanous, mostly 5-10 cm., watery 

 flesh coloured, browner when old ; gills very numerous, 

 delicate, white, receding with a decurrent tooth; stem 

 cartilaginous, stuffed usually expanding at the base. 

 Spores hyaline, smooth, 6x3^. 



Common, chiefly amongst wattle trees. 



Flammula iwasina, C. et M. Pileus convex, 

 subumbonate, mostly 5 cm., dull green in centre fading 

 to dull yellow towards the margin ; gills fairly numer- 

 ous dull yellow, receding with a decurrent tooth ; stem 

 bold, 5-10 cm., pale yellow, solid, pithy in middle. 

 Spores brown, sanooth, 8 x 4 /i. 



Common in forests.
