DESCRIBED SPECIES

(WITH PLATES XXI-XXIII AND SIX FIGURES) 
Introduction 
hs has been shown in a former article (6), the term bulbil, as 
_ applied to fungi, refers to reproductive bodies of more or less 
definite form, composed of a compact mass of homogeneous or 
heterogeneous cells which may be few or many in number, but 
which are usually developed from primordia of more than one 
cell. This mode of reproduction is common among certain fungi - 
and constitutes the only known means among others. Many 
_ Of these structures superficially resemble the “spore-balls” of 
_ Urocystis or Tuburcinia among the smuts, but differ from them in 
their manner of germination. In general appearance and mode — 
of development the bulbils of Papulospora spinulosa Hotson might — 
readily be taken for “‘spore-balls”’ of Urocystis, but, on germination, ae 
Promycelia bearing sporidia such as are produced by” the smuts are _ re
