HYPHOLOMA. 379 



of the pileus (appendiculate) ; not forming a distinct ring 

 round the stem ; gills adnate or sinuate and adnexed, often 

 seceding (separating from the stem, and then appearing as 

 if free) ; spores brownish-purple, sometimes intense purple.

 p. 202. 



Mostly caespitose and growing on wood, when growing on 

 the ground, often springing from buried wood, roots, &c. 



Distinguished from Stropharia by the absence of an inter- 

 woven ring on the stem ; when a trace of the ring is present, 

 it is in the form of cobweb-like fibres, and very scanty. 



Hypholoma agrees in structure with Hebeloma, Entoloma, 

 and Tricholoma. 



Veil woven into a loose cobweb-like texture, adhering to 

 the margin of the pileus, not forming a distinct ring round 

 the stem; the last character separates the present genus 

 from Agaricus ; from Psathyra it is known by the stature, 

 habit, and presence of an evident veil. Known amongst 

 allied genera by the tufted mode of growth, growing on 

 wood, pileus not furnished with a separable pellicle, gills in 

 some species almost deliquescent- (Fries.)
