CHAPTER V 



THE INOCYBE SUB-TYPE AND ITS INTERMEDIATE POSITION 

 Greneral Remarks — Characters of the Inocybe Sub-type 



General Remarks, — The Panaeolus, Psathyrella, Bolbitius, and 

 Armillaria Sub-types, when typically developed, can be readily 

 distinguished from one another with the help of the microscope. 

 The Inocybe Sub-type, with which this Chapter is concerned, stands 

 in a position intermediate between the Panaeolus and the Armil- 

 laria Sub- types and serves, more or less, to bridge over the gap 

 between them. This is the most unsatisfactory Sub-type with 

 which we have to deal, and in it have been placed those fungi in 

 which (1) the mottling of the hymenium is very feebly developed, 

 so that one cannot detect it with the naked eye or even in any very 

 clear manner with the microscope, but in which, nevertheless, (2) the 

 basidia of like age are not widely scattered over the hymenium 

 but come up in tiny irregular groups or strings. We seem to have 

 presented to us fungi which are passing from the Armillaria to the 

 Panaeolus Sub-type, or vice versa, and in which the basidia of like 

 age come up not isolated from one another but in small associations. 

 The species of Hymenomycetes which I have been unable to 

 place in either the Panaeolus or the Armillaria Sub-type, but which 

 appear to occupy an intermediate position and have therefore been 

 included in the Inocybe Sub-type, are as follows : 



Inocybe asterospora Psathyra corrugis 



Galera tenera (Fig. 53) Russula emetica 



Characters of the Inocybe Sub-type. — The Inocybe Sub-type 

 of fruit-body possesses all the characters already described for the 

 Aequi-hymeniiferous Type : the gills are wedge-shaped in cross-
