Fam. III. MyrraNGIACEL. 
Two species of Myriangium have been found in Victoria, one 
of which is new to science. The new species has several pecu- 
liarities, which may give a little help in elucidating the affinities 
of this strange family. 
The whole plant is covered with scyphophoroid apothecia 
standing out in all directions, and of various sizes and stages of 
development. The epithecium is almost identical in texture 
with the epithallus, but is generally concave and slightly rufescent. 
In old apothecia it is worn into cavities, which give it a granulato- 
rugulose appearance. The spores are longer and narrower than 
those of the species hitherto known, and in general form re- 
semble those of Collema multipartitum figured by Nylander in his 
‘Synopsis.’ Both thallus and apothecia contain granular gonimia, 
which are usually, if not invariably, conglomerate. When a dried
