on the lower side are often shorter than those on the upper. 
Consequently, when the fructification is viewed from below, 
large specimens show an oval opening, through which the orange- 
coloured disc may be visible. The sporodochium then resembles 
a small Otidea. 
The marginal hyphae may be united into a continuous layer 
surrounding the disc, or divided into teeth or segments to varying 
depths from the apex. In some forms, this envelope is continuous 
up to the apex on the upper side, and iui down to the base 
in the median line on the lower. 
The conidiophores are short, as a rule. They are at first un- 
branched and about 30 » long, but become branched and about 
60 long. They resemble the conidiophores of Micrvocera in 
diameter and branching, but are very considerably shorter. It 
is possible that they may attain a greater length in some species, 
but in all the cases observed, the ultimate branches are short, 
and the conidiophore branched almost from the base. Probably 
because of the shortness of the conidiophores, ladder connec- 
tions between them are absent, or at least rare. 
The conidia are long, three to five septate with long aseptate 
tips, and, in the forms examined, are usually regularly curved 
from tip to tip (Plate V, fig. 17). They remain for some time 
enclosed within the tip in an orange, or coral-red, mass, the 
apex of which projects slightly, but, judging from the available 
specimens, they are more readily dispersed than those of the 
true Microcera. 
The structure of this conidial form is evidently quite different 
from that of the Microcera described by Desmaziéres; and it 
does not appear to agree with any existing genus. I therefore 
propose for it a new genus, Pseudomicrocera. 
PSEUDOMICROCERA. Sporodochium conical; base ovoid, or 
cylindric, or pulvinate, parenchymatous, or composed of inter- 
woven irregular hyphae, surmounted by a discoid layer of 
conidiophores with a marginal zone of long hyphae, united into 
a continuous sheet or into fascicles of varying breadth, which 
are connivent at the apex; conidiophores branched; conidia elon- 
gated, narrow, curved, septate, hyaline. 
The following forms of Pseudomicrocera have been examined.

The sporodochia are oblique or horizontal. The sale at first 
has a radiating byssoid margin, which develops into a more 
compact yellowish-white stroma, at the side of, or covering, the 
scale. The sporodochia may arise from the margin of the scale, 
or from the stroma. In some cases the sporodochium arises at
