CLASSIFICATION OF AGARH 



pellicle continuous and entirely separable, margin becoming 

 strongly tuberculate-striate. FLESH thin, white, ool changing 

 color, soft. GILLS bright ochraceous-yellow (flavus, B . white 

 .-it first, rather narrow, broadest in front, narrowed and adnexed 

 behind, snbdistant a1 maturity, dusted by the spores. STEW 1-8 

 cm. Long, L-2 cm. thick, subequal to ventricose, soft and fragile, 

 Loosely stuffed then cavernous (but nol from grubs), wliite, rarely 

 tinged with delicate pink, slightly wrinkled, subglabrous. SPORES 

 subglobose, 7-9 micr., echinulate, nucleate, brighl ochre-yellow in 

 mass. TASTE mild. ODOB Done CYSTIDIA very few. Sfwo- 

 hymenium narrow, sharply differentiated from gill-trama. 



Solitary or scattered. In mixed \\ Ls of hemlock and beech, 



among beds of wliite pine needles at New Richmond ; an g grass, 



etc., in oak won. is al Ann Arbor. July-October. Frequent. 



This very fragile Bussula is known from the other members of 

 the "Fragiles" group by its medium size, brighl yellow-ochraceous 

 spores and gills, tbe hollow, often subventricose stein, the mild taste 

 and the pinkish-yellow to peach-colored pileus. The stem is some- 

 times enlarged at tbe apex, sometimes at tbe base, always fragile 

 Very few of our Russulas have such bright-colored spores and gills. 

 Tbe color of tbe cap varies rather rarely to a deeper red on the one 

 hand or to ochraceous tan and straw color on the other. The flesh 

 docs not change on bruising, and Hie odor is not noticeable even in 

 age. It is very different from R. mtegra IV. It approaches B. 

 nitida and is no doubt the plant usually referred to that species 

 in this country. It differs in tbe lack of the nauseous, disagreeable 

 odor which is known to be constant in R. nitida. I formerly refer 

 red it to R. barlae Quel, which, however, is described as compact 

 and firm. R. aurata Ft. has idlls with a chrome-yellow edge.' 



Micro-chemical tests: G. (Flesh turns blue quickly ; gills become 

 greenish-blue.) S V. (Flesh and gills slowly pinkish then blue.) r 



S. (Cystidia colored brown.)
