Pinus. As these trees are not indigenous and this species 
of fungus is found in fir woods in Hngland, it is almost 
certainly an introduction, probably with seedling pines. It 
is exceedingly remarkable that the Rhizopogon should 
require for its development some constituent derived from 
the pine, which apparently must be present in the soil 
in very small amount as the fungus may be found some 
little distance away. Spores elongated, almost colourless, 
often biguttulate, 7°2 to 8°5 x 2°7 to 3°4v. Hawkesbury 
River, June 1913; Leura, October 1914. 
Hymenogaster ? sp.—We have a sinall reddish-brown 
species, pear-shaped and about 4 in. long, which has a well- 
marked sterile base and very finely warted (oil immersion 
lens) oval brown spores. These features seem to place it 
in the genus Hymenogaster. The substance is minutely 
cellular and of a pallid cinnamon tint, the peridium is quite 
smooth with no attached fibrils and the spores are oval, 
8°5 to 10°4 x 7p, very finely warted. Sydney district. _ 
Hydnangium brisbanensis.—We have taken this species 
on several occasions. The gleba is very pale, size up to # in. 
long, and the spores spherical or subspherical, almost 
colourless, 7°2 to 10°4, with an apiculus, and sometimes 
very distantly warted, sometimes more closely warted.

River (July), Terrigal (June, 1914). 
Hydnangium tasmanicum (?)—Our specimen is placed 
doubtfully under this heading. There is no sterile base 
and the spores are warted. Our spores are oval, however, 
and the spores of H. tasmanicum are given in Cooke as 
globose. Specimen irregular, about + in. diameter, when 
fresh covered with a powdery whitish to brownish bloom, 
tending to split irregularly above, on section dark cinna- 
mon, minutely areolate. Spores oval, 14 x 9», brown,
