Copr opinions Fungi . II, 
branchlets which bear a great number (ioo or more) of long-stalked 
sporangiola ; terminal sporangium globose, blackish, about 168 n in 
diam., with an ovate, colourless, smooth columella ; sporangiola 
pyriform, drooping, about 25 /x in diam., white, columella not evident, 
spores broadly ellipsoid, 6-8 /x long, 4-5 /x broad, smooth. 
Hab . — On Mouse-dung, Kew, Oct. 1901. (Distrib. — France; on 
dung ; also cultivated on bread and Horse-dung.) 
A very beautiful and apparently uncommon species. In the Kew 
examples, no terminal sporangia were observed. The species is at 
once recognized by the mass of densely crowded pyriform sporangiola 
on rather long delicate stalks ; the sporangiola arise laterally from the 
main axis in the manner shown at Fig. 108. The Mouse-dung on 
which the Fungus appeared was originally sent from the Gold Coast by 
Mr. W. H. Johnston ; the dung was kept damp at Kew for a week or 
so, at the end of which time the Helicostylum appeared in some 
plenty.

Forming very minute scattered patches on Sheep's dung. Dis- 
tinguished among the species of the genus by the amber colour of all 
its parts. 
Aeromonium flmicolnm, sp. nov. (Fig. 92). 
Caespitulis albis minutis ; hyphis repentibus liliformibus sparse 
septatis furcatis hyalinis 4 /x crassis, ramulis fertilibus subulatis 5-8 /a 
longis hie inde in caespitulis irregulariter positis; conidiis globosis 
hyalinis 6-8 /x diam. 
Hab . — In fimo cuniculorum, Kew, Nov. 1900. 
Forming minute snow-white tufts which sometimes become confluent. 
The short fertile branchlets or conidiophores are arranged in clusters 
at intervals along the prostrate hyphae. Apparently allied to A. 
Brassicae, Sacc. and Schulz, but distinguished by the distinct clusters 
of conidiophores.
