orange colour, which is communicated by the
layer of spermatia, unmixed with spores. These spots retain their
bright colour, while the remainder of the plant becomes pale, or
covered with a white dust. The spermatia are very small, spherical,
and smooth, scarcely equalling .002 _mm._ They are sessile, sometimes
solitary, sometimes three or four together, on the slightly swollen
extremities of certain filaments of the weft of the fungus.[P] Tulasne
found it impossible to make these corpuscles germinate, and in all
essential particulars they agreed with the spermatia found in
ascomycetous fungi.

In the genus _Dacrymyces_, the same observer found the structure to
have great affinity with that of _Tremella_. The spores in the species
examined were of a different form, being oblong, very obtuse, slightly
curved (.013 - .019 x .004 - .006 _mm._), at first unilocular, but
afterwards triseptate. The basidia are cylindrical or clavate, filled
with coloured granular matter; each of these bifurcates at the summit,
and gradually elongates into two very open branches, which are
attenuated above, and ultimately each is crowned by a spore. There are
to be found also in the species of this genus globose bodies,
designated "sporidioles" by M. Leveille, which Tulasne took
considerable care to trace to their source. He thus accounts for
them:--Each of the cells of the spore emits exteriorly one or several
of these corpuscles, supported on very short and very slender
pedicels, which remain after the corpuscles are detached from them,
new corpuscles succeeding the first as long as there remains any
plastic matter within the spore. The pedicels are not all on the same
plane; they are often implanted all on the same, and oftenest on the
convex side of the reproductive body. These corpuscles, though placed
under the most favourable conditions, never gave the least sign of
vegetation, and Tulasne concludes that they are spermatia, analogous
to those produced in _Tremella_. The spores which produce spermatia
are not at all apt to germinate, whilst those which did not produce
spermatia germinated freely. Hence it would appear that, although all
spores seem to be perfectly identical, they have not all the same
function. The same observer detected also amongst specimens of the
_Dacrymyces_ some of a darker and reddish tint, always bare of spores
or spermatia on the surface, and these presented a somewhat different
structure. Where the tissue had
