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 Tubercular i a ; 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

 Stipitate, rooting, cups nearly plane, disc golden-yellow. St.
