THE RUSTY-SPORUD AGARICS 281 



Naucoria. Fr. 



Naucoria, a nut shell. The pileus is some shade of yellow, convex, inflexed, 

 smooth, flocculent or scaly. The gills are attached to the stem sometimes nearly 

 free, never decurrent. The stem is cartilaginous, confluent with the cap but of 

 a different texture, hollow or stuffed. The veil is absent or sometimes small 

 traces may be seen attached to the rim of the pileus, in young plants in the form 

 of flakes. The spores are of various shades of brown, dull or bright. They 

 grow on the ground on lawns and rich pastures. Some on wood. 



Naucoria hamadryas. Fr. 

 The Nymph Naucoria. Edible. 



Hamadryas, one of the nymphs whose life depended upon the tree to which 

 she was attached. 



The pileus is one to two inches broad, rather fleshy, convex, expanded, 

 gibbous, even, bay-ferruginous when young and moist, pale yellowish when old. 



The gills are attenuated, adnexed, almost free, rusty, slightly ventricose, 

 somewhat crowded. 



The stem is hollow, equal, fragile, smooth, pallid, two to three inches long. 

 The spores are elliptical, rust-color, 13- 14x7^. 



This is quite a common species, often growing alone along pavements, under 

 shade trees, and in the woods. The caps only are good. Found from June to 

 November. 



Naucoria pediades. Fr. 

 The Tan-colored Naucoria. EdibeE. 



Pediades is from a Greek word meaning a plain or a field, referring to its 

 being found on lawns and pastures. 



The pileus is somewhat fleshy, convex, then plane, obtuse or depressed, dry, 

 finally opaque, frequently inclined to be minutely rivulose. 



The gills are attached to the stem but not adnate to it, broad, subdistant, 

 only a few entire, brownish, then a dingy cinnamon. 



The stem is pithy or stuffed, rather wavy and silky, yellowish, base slightly 

 bulbous. The spores are of a brownish-rust color, 10-12x4-5/*,. 



If the small bulb at the base of the stem is examined, it will be found to 

 be formed chiefly of mycelium rolled together around the base. It is found on 

 lawns and richly manured pastures from May to November. Use only the caps. 

 This plant is usually known as semiorbicularis.
