almost to the base, sometimes undivided for twice the length of
the spore, sterigmata 1-5 lengths of spore. (Fig. 86.)
Mr. Fred. Currey {fourn. Linn. Soc. vol. v. p. 181, 1861) was
the first to call attention to the cloven basidia in this species, and
to point out the resemblance in the fruit to some of the Tremellinacem.
Mr. George Massee {British Fungus Flora, vol. i. p. 65) has placed
Tremellodon at the end of the Tremellinaceoi, but the nature of the
basidium and sterigmata is an insufficient reason for the removal,
and if adopted many other removals would have to be made.
