very delicate white bloom, hollow ; spores elliptical, 

 8-10 x 3 5 /x. 



Agaricus (Tricholoma) putidus, Fries, Epicr., p. 54 ; Cke., 

 Hdbk., p. 44; Cke., Illustr., pi, 172. 



Among pine leaves, &c. 



Smell strong, rancid. Eesembling Collybia rancida in 

 habit and smell, but at once known by the soft stem being 

 entirely fibrous, and not at all cartilaginous, and not rooting. 



ARMILLARIA. Fries. 



Pileus symmetrical, more or less fleshy ; gills adnate or 

 slightly decurrent, stem central, passing continuously into 

 the flesh of the pileus, furnished with a ring ; spores white , 

 elliptical, smooth. 



Armillaria (as a subgen. of Agaricus), Fries, Syst. Myc., L 

 p. 26 ; Cke., Hdbk., p. 21. 



The principal points to be observed in the present genus 

 are, gills more or less attached to the stem, and the presence 

 of a ring. In a few species the ring disappears at an early 

 period, when the species somewhat resemble those of Tricho- 

 loma, but are distinguished by the gills not being sinuate ; 

 whereas the gills are generally sinuate, more or less, in those 

 species having a permanent ring. In fact but for the 

 presence of a ring, the species of Armillaria would fall 

 naturally into three sections, belonging respectively to 

 Tricholoma, Clitocybe, and Collybia. 



ANALYSIS OF THE SPECIES. 



* Gills sinuately adnexed ; stem fleshy, substance equal 

 throughout, furnished with a ring (resembling Tricholoma 

 with a ring). 



** Gills narrowed behind, more or less decurrent, not 

 sinuate ; stem solid, with a ring (resembling Clitocybe, but 

 with a ring). 



*** Gills equal behind, adnate ; stem cartilaginous outside 

 (resembling Collybia, but with a ring).
