The exceptional color of L. indigo will halt anyone with ordinary observing power. It is unnecessary to describe it further. Being a large, stout plant it frequently lifts the leaf mat as it pushes upward, making leaf-mounds under which it is hidden, as do many of the Cortinarii. But even in such instances there are usually a few solitary plants standing prominently forth as sentinels. It is edible, but coarse. Good flavor. =L. chelido´nium= Pk. =Pileus= 2–3 in. broad, at first convex, then nearly plane and umbilicate or centrally depressed, _grayish-yellow or tawny_, at length varied with bluish and greenish stains, often with a few narrow zones on the margin. =Gills= _narrow_, close, sometimes forked, anastomosing or wavy at the base, _grayish-yellow_. =Stem= 1–1.5 in. long, 4–6 lines thick, short, subequal, hollow, colored like the pileus. =Spores= globose, 7.5µ. =Milk= sparse, _saffron-yellow_; taste mild. Sandy soil, under or near pine trees. Saratoga and Bethlehem. The milk of this species resembles in color the juice of celandine, Chelidonium majus. It is paler than that of L. deliciosus. By this character and by the dull color of the pileus, the narrow lamellæ, short stem and its fondness for dry situations, it may be separated from the other species. Wounds of the flesh are at first stained with the color of the milk, then with blue, finally with green. A saffron-color is sometimes attributed to the milk of L. deliciosus, which may indicate that this species has been confused with that, or that the relationship of the two plants is a closer one than we have assigned to them. _Peck_, 38th Rep. N.Y. State Bot. Mt. Gretna, Pa. In mixed woods, gravelly low ground. September, October. _McIlvaine._ A score or more solitary specimens were found and eaten. The substance and flavor are not distinguishable from L. deliciosus, which is lauded to the summit of good toadstools. =L. subpurpu´reus= Pk.—_sub_, under; _purpureus_, purple. =Pileus= at first convex, then nearly plane or subinfundibuliform, more or less spotted and zonate when young, and moist _dark-red with a grayish luster_. =Gills= close, _dark-red_, becoming less clear and sometimes greenish-stained with age. =Stem= equal or slightly tapering upward, soon hollow, often spotted with red, colored like the pileus, sometimes hairy at the base. =Spores= subglobose, 9–10µ. =Milk= _dark-red_. =Pileus= 2–3 in. broad. =Stem= 1.5–3 in. long, 3–5 lines thick. Damp or mossy ground in woods and swamps. July and August. At once known by the peculiar dark-red or purplish hue of the milk, which color also appears in the spots of the stem and in a more subdued tone in the whole plant. The color of the pileus, gills and stem is modified by grayish and yellowish hues. In age and dryness the zones are less clear, and dried specimens can scarcely be distinguished from L. deliciosus. _Peck_, 38th Rep. N.Y. State Bot. I have not seen this species.
