134 INTRODUCTION TO THE STUDY OF FUNGI 



done with the Rhodosporae, so we might indicate the analogues 

 of the Leucosporae in the Ochrospor&e, in so far as they are 

 represented. There is no, genus which corresponds with 

 Amanita, but Locellina or Acetabular 'ia, whichever name we 

 select, is equivalent to Amanitopsis. Zepiota and Schulzeria 

 have no analogue, but Armillaria has a correspondent in 

 Pholiota. Tricholoma is most nearly represented by Hebeloma, 

 and in some degree by Inocybe, the essential difference between 

 these two genera being the fibrillose cuticle in the latter, and 

 the smooth viscid cuticle in the former, both of which are 

 represented in subsections of Tricholoma. Glitocybe is repre- 

 sented by Flammula in some of its species only, which have' 

 decurrent gills, whilst Pleurotus has its analogue in Crepidotus. 

 For Collybia ' we have Naucoria ; for Mycena there is Galera ; 

 and Omphalia is recognised in Tubaria. It is only in Inocybe, 

 that we meet with irregular spores such as are not uncommon 

 in the Rhodosporae. 



The total number of recorded species is estimated at 1157, 

 as against 366 of the Rhodosporae. The large genus Gortinarius 

 comprises some 400 species, all of which are terrestrial, and 

 only subtropical at considerable elevations. Should Bolbitius 

 be included, it differs from all the rest in the thin membra- 

 naceous pileus, in which respect it is analogous to Hiatula 

 in the Leucosporae, and to some species of Coprinus in the 

 Melanosporae. 



The fourth and last primary division of the Agaricineae, 

 according to Saccardo, is Melanosporae, in which he combines 

 the Pratellae of Fries with the Coprinarii, and adds thereto the 

 genera Coprinus, Bolbitius (ochrosporous), Gomphidius, Anthra- 

 cophyllum, and Montagnites. In some cases it is difficult to 

 distinguish dark purple -brown spores from black, but this is 

 hardly sufficient reason for combining them. Mr. G. Massee 

 felt this to be the case, and in his British Fungus Flora he 

 adopts two divisions instead of one, namely, the Porphyrosporae 

 and the Melanosporae. After all there is no great principle at 

 stake, although personally we would rather, if a coalition be 

 considered advisable, that the two subdivisions were kept 

 separate as Porphyrosporae and Melanosporae under a common 

 designation. Following the same course that we have adopted
