“Vulva ex area sat parva subpentagona, nitida, pallide 
fusca, ad utrinque angulum lateralem macula nigra notata 
constat, que postice truncata est, lateribus rectis sensim 
angustato-acuminata: hee area excavata est et septa cruci- 
formi munita, cujus ramus posterior, reliquis longior, foveas 
duas oblongas separat. Pone hance aream callum fortem 
transversum convexum nitidum pallide fuscum video.” 
Thorell says of this species, the form of whose vulva is 
sufficiently difficult to grasp from the description, “ pedibus 
fongis et forma vulvz notabili satis distincta est.”

“ Vulva figure fungi (Agarici) humilis sat similis est: ex 
callo maximo, alto, deplanato, transverso et triplo-quadruplo 
latiore quam longiore constat, qui postice ample rotundatus est, 
antice in medio quasi in petiolum basi angustum, tum dila- 
tatum productus et utrinque, apud eum, paullo emarginatus : 
apices rotundati hujus calli (pallide fusci) nigri sunt.” 
The general form of the vulva is clear from the description, 
and proves the species to be quite distinct from the females 
taken in Pinang by Mr. Flower, described below, though it 
must be closely allied to another form before me from Java, 
as well as to valvularis.
