both. The hairs of the pileus are coarse and vanish so easily that they 

 are preserved with difficulty in the dried specimens." (Charles H. Peck.) 



The illustration, Fig. 276 (on last page), shows plants in various 

 stages of development. The dense floccose tufts are seen plainly on the 

 young specimens, and even on those quite well developed. Specimens in 

 age showing these tufts of hairs most conspicuously were selected for the 

 photograph. From the specimens on the left scarcely any are to be seen. 

 The plants are but 3 cm. high, the caps about one and a half cm. wide, and 

 the stems one to two mm. in diameter. 



Specimens later were sent to Professor Atkinson, who considers them 

 Dccoiiica atrorufa, (named by Schaeffer originally as Agaricus 

 atrorufus) ; some others use the name Psilocybe atrorufa for this. A 

 final decision may yet have to be deferred in reference to this plant. Un- 

 fortunately the greenhouse bench gave way and the soil in which specimens 

 were growing had to be removed. It is hoped that plants may be found 

 later and their taxonomic status satisfactorilv settled.

 better the yellow strands of mycelium at the base of the stem, by means of which the 

 attachment to the sphagnum is intimately secured. See description of the species on 

 other page.
