COLLECTED IN VICTORIA, AUSTRALIA. 361 
this tribe is as largely represented in the Southern as in the 
Northern hemisphere. Probably the minuteness of the plants 
has caused them to be overlooked by collectors visiting the 
Southern hemisphere. As far as Victoria is concerned, they seem 
to have been overlooked altogether. The writer was the first to 
publish the discovery in this colony of a lichen of this tribe; and 
he has found them in great abundance in very many places and 
of many kinds, 
The following list contains 31 varieties, if not species, found 
in Victoria, of which 27 at least seem to be new to science. On 
comparing them with Nylander’s descriptions, the Victorian 
plants, as a rule, seem to have somewhat smaller spores and a 
more developed thallus than those found elsewhere. The thalli 
of Calicium niveum, C. flavidum, and C. roseo-albidum are spe- 
cially remarkable for their thickness. It is notable also that the 
Species which in other lands grow on the wood of the oak, in the 
absence of that tree in Victorian forests choose the eucalypts, 
whose timber is similarly dense. All the Calicei hitherto found 
in Victoria grow on dead wood or dead bark, or the thallus of 
other lichens. None are saxicole. The following descriptions 
and relative drawings are the result of repeated and careful 
autopsy. 
32. SPHINCTRINA MICROCEPHALA, Wyl., var. TENELLA, F. Wils. 
Apothecia nigro-fusca nitida tenella, alt. 3 mm., capitulis tur- 
binato-globosis (diam. '1 mm.) in stipitibus (crass. ‘05 mm.) 
elevatis, excipulis pyrenodeis. Spore simplices nigricantes fusi- 
formi-globosæ nonnullæ difformi ellipsoideæ, long. ‘Ol mm., pa- 
rietibus crassiusculis.— Habitat super Pertusariam quandam ad 
ramulos Hymenanthere Banksü in Maffra, Gippsland. 
Similis S. microcephalæ a Nylandro descriptz (Meth. Syn.) sed 
stipites speciminum Victorianorum s&pius longiores et graciliores 
et capitula minora et spore minutiores sunt. In plagis paucis 
minutis (diam. 6-12 mm.) conferta inventa est. Specimina simi- 
liora typo inventa sunt prope Sydney, New South Wales, etenim 
prope Brisbane, Queensland, non conferta sed sparsa et in plagis 
majoribus quam var. tenella. 
P.S. Typus nuper minutus in Maffra, Gippsland. 
33. CALICIUM CHRYSOCEPHALUM, Var. FILARE, Ach. 
Thallus obsoletus. Apothecia minuta, alt. '7-1 mm., stipitibus 
gracilibus circa 05 mm. crass., capitulis turbinatis citrino sut-
