to have great aflinity with that of J'remella. The spores in the 
species examined were of a different form, being oblong, very 
obtuse, slightly curved (018 —'019 x -004—-006 mm.), at first 
unilocular, but afterwards triseptate. The basidia are cylin- 
drical 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. Léveillé, 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 planc; 
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 
‘Sspermatia, analogous to those produced in Zremella. 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 iden- 
tical, they have not all the same function. The same observer 
detected also amongst specimens of the Daerymyves 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 turned red it was sterile, the constituent 
filaments, ordinarily colourless, and almost empty of solid matter, 
were filled with a highly-coloured protoplasm ; they were of less 
tennity, more irregularly thick, and instead of only rarcly pre- 
senting partitions, and remaining continuous, as in other parts 
of the plant, were parcelled out into an infinity of straight or 
curved pieces, angular and of irregular form, especially towards 
the surface of the fungus, where they compose a sort of pulp, 
varying in cohesion according to the dry or moist condition of
