AGARICINI. 



Hygro- 

 phorus. 



becoming pale, streaked withjibrils. Stem equal, shining. Gills 

 becoming glaucous. 



Stiff. It seems to be a young state of H. nitratus, scorched by the sun, 

 but it is reckoned distinct by Persoon and others. Odour the same, but 

 weaker. 



In mixed woods. Pass of Killiecrankie. 1877. Aug. 



Name glaucus, glaucous ; nitens, shining. Fr. Hym. Eicr. p. 421. B. & 

 Br. n. 1671. S. MycoL Scot. n. 546. Ag. Batschf. 192. 



Lactarius. GENUS IX. Lactarius (lac, milk). Fr. Epicr. p. 333. 



Hymenophore continuous with the stem. Gills unequal, mem- 

 branaceous-waxy, slightly rigid, milky, acute at the edge. Spores 

 globose, white, rarely yellowish. Fleshy fungi, growing on the 



ground (with two exceptions), putres- 

 cent, pile us depressed, gills adnato- 

 dectirrent and often branched. 



A very distinct genus and easily 

 recognised. Pileus in some species 

 zoned which is peculiar to this genus. 

 Watery milk is never a normal fea- 

 ture of the genus, but where it does 

 occur it is owing to the dampness 

 of the station where the specimens 

 have grown. Fr. Hym. Eur. p. 421. 

 The nearest allies to the Lactarii 

 are the Russufa, which are at once 

 distinguished by their want of milk. 

 The genus includes some species 

 which are edible and delicious, while 

 others are exceedingly poisonous. 



The best mark of distinction of species is the nature of the 

 milk. 



Tribe I. PIPERITES (piperitis, pepper-wort). Stem central. Gills un- 

 changeable, naked, not changing colour and not pruinose. Milk at the first 

 white, (commonly) acrid. 



* TRICHOLOMOIDEI. Pileus viscid "when moist, margin at first involute, 

 tomentose. 



** LlMAClNl. Pileus viscid when moist, pelliculose, margin naked. 



*** PIPERATI. Pileus without a pellicle, hence absolutely dry, most fre- 

 quently unpolished. 



Tribe II. DAPETES (daps, food). Stem central. Gills naked ; milk at the 

 first deeply coloured. 



XL IX. Lactarius snbdiilcis. 

 One-third natural size.
