Leucosporae 



Lactarius distans Pk. Distant-gilled Lactarius. PileilS firm, Lactarius. 

 broadly convex or nearly plane, umbilicate or slightly depressed in the 

 center, with a minute velvety pruinosity, yellowish tawny or brownish 

 orange. Lamellae rather broad, distant, adnate or slightly decurrent, 

 white or creamy yellow, the interspaces venose, milk white, mild. 

 Stem short, equal or tapering downward, solid, pruinose, colored like 

 the pileus. Spores subglobose. 9-1 ip, broad. 



The distant-gilled Lactarius is similar to the orange Lactarius in 

 color, but in other respects it is quite distinct. The short stem, widely 

 separated gills and pruinose surface of the cap are distinctive features. 

 The cap is broadly convex and often has a small central depression or 

 umbilicus. In some cases it becomes nearly plane or even slightly fun- 

 nel-shape by the spreading or elevation of the margin. The surface, 

 specially in young and in well-developed specimens, has a soft pruinose 

 or almost velvety appearance to the naked eye, and when viewed 

 through a magnifying glass it is seen to be covered with minute per- 

 sistent granules. The surface is sometimes wrinkled and frequently it 

 cracks in such a way as to form small angular or irregular areas. 

 The color is a peculiar one, varying somewhat in shade, but with tawny 

 hues prevailing. It has been described as yellowish tawny and brown- 

 ish orange. The flesh is white or whitish and has a mild taste. 



The gills are wide apart, somewhat arched in specimens having a con- 

 vex cap and slightly decurrent in those with fully expanded or cen- 

 trally depressed caps. Their color is white or creamy yellow and in 

 old and dried specimens they have a white pruinosity as if frosted by 

 the spores. The milk is white and mild. 



The stem is short, rarely more than an inch long, and is cylindric or 

 tapering downward. It is solid and colored and clothed like the cap. 



The cap is I to 4 in. broad; the stem is usually about i in. long, 4 

 to 8 lines thick. It is found in thin woods, bushy places and pastures 

 from July to September. It is similar to the orange Lactarius, L. vol- 

 emus, in its edible qualities. Peck, $2d Rep. N. Y. State Bot.
