PSILOCYBE 361 



HYPHOLOMA 



Pileus fleshy, margin incurved when young ; stem central, 

 veil appendiculate, not forming a distinct ring ; gills adnate 

 or sinuate, spores purple-brown. 



Raspberry root rot (Hypholoma fasciculare, Fries.), although 

 one of the commonest and most generally distributed of 

 British fungi, has not been proved to be parasitic in this 

 country. Dr. M'Alpine, however, states that this species is 

 very destructive to raspberries in Victoria, forming a dense 

 white mycelium round the roots. 



Growing in dense tufts. Taste bitter. Pileus 1-3 in. 

 across, tawny, margin yellow ; gills yellow, then greenish, 

 stem yellow. 



M' Alpine advises drainage and liming the soil, removal 

 and burning of diseased plants. The addition of salt to the 

 lime in the proportion of two of lime to one of salt is 

 recommended. 



PSILOCYBE (FRIES). 



Pileus smooth, margin at first incurved ; gills and spores 

 at length brownish or purplish ; stem central, cartilaginous, 

 hollow or stuffed, veil absent or rudimentary. 



A cereal infesting agaric. Dr. Yungner-Posen describes 

 the occurrence of minute sclerotia on fading leaves of seed- 

 ling rye and wheat. The sclerotia proved to be those of 

 Psilocybe Henningsii (Yungner-Posen). The sclerotia are 

 about the size of a clover seed, sometimes a little larger, 

 yellow, then reddish-brown. 



Pileus grey, then tinged brown, edge minutely striate, 10- 

 18 mm. diam., gills broadly adnate, grey then blackish; stem 

 slender, flexuous, grey, tinged brown, 2-3 cm. long, springing 

 from a sclerotium; spores elliptic-fusoid or ovate, reddish- 

 brown, 10-13x6-7 /A, smooth.

Hemi - parasitic agarics. Hennings points out that in 

 addition to the list of agarics usually included as being 

 more or less of a parasitic nature, many other species 

 of gill-bearing fungi are constantly met with on the dead 

 stumps of trees, sometimes on living trees, and suggests that
