Massee has removed 2040 and made it the sole type of a new
genus, Dacryopsis. It is undesirable to break up such a small and
natural genus as Ditiola. Dacryopsis is said to be distinguished from
Ditiola by having the hymenial surface at first covered with conidio-
phores and conidia as in Tubercularia ; but this is hardly a distinction
of generic value as conidia are present in some species of Tremella
and not in others. Species 2039 2041
