BASIDIOMYCETES. 
Section LXXXIV. This group is composed of two large sub-groups, the 
Hymenomycetes and the Gastromycetes, and derives its name from the dasıdia 
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 Aymenia 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
