BASIDIOMYCETES. 



SECTION LXXXIV. This . group is composed of two large sub-groups, the 

 Hymenomycetes and the Gastromycetes, and derives its name from the basidia 

 which are proper to all members of the group and abjoint spores acrogenously. These 

 organs, which were described above on pages 63, 64, are closely crowded together and 

 usually stand parallel to one another, forming hymem'a on or in the compound 

 sporophore; they are not unfrequently accompanied by sterile hyphal branches, 

 which here as elsewhere may be included in Montagne's term * paraphyses (see page 

 53). The basidia appear almost always, it may be said indeed uniformly, as the
