repeated comparison with Hepp's specimens and drawings tbat 
the following species has been classed with the Stigonemata :— 
1. STIGONEMA EPHEBEOIDES, F. Wils., sp.nov. (Pl. XLIX. 
fig. 1.) 
Thallus fusco-ater opacus pulvinato-contextus filiformis tenel- 
lus, subsecundc-ramosus, presertim ad apicem. Alt. ad 3 mm., 
crass. ad *1 mm. adtingens.—Habitat super saxa granitica sub- 
alpina in Mt. Macedon (alt. 3400 ped.). ; 
Cortex e membrana tenuissima olivacea constat, per quam vise 
sunt, saltem in ramulis juvenilibus, cellule transverse ordinate, 
granula gonima 1-3 vel plura continentes. Ramuli senescentes 
minus translucidi, atque a granulis plus prominentibus magis 
rugulosi facti sunt. Granula gonima dilute olivaceo-virentia sunt, 
et magnitudine formaque valde diversa, plerumque '01 mm. diam. 
Supra thallum et eoncolora et mox separabilia inveniuntur organa 
minuta lenticularia, '2 mm. diam., quorum textura videtur eadem 
que thalli. 
Fig. 1 exhibet ramuli thallini apicem. 
Fam. II. COLLEMACEI. 
This family is well represented in Victoria, considering the 
dryness of the climate. Twenty-three species have been found, 
of which eleven seem to be new to science. Of the rest four are 
new varieties. One of the new species has been assigned to 
Wallroth's obsolete genus Obryzwm, owing to its unmistakably 
endocarpoid apothecia and its cellular thalline cortex. Some of 
this family are abundant enough, especially Lichina confinis, 
Leptogium olivaceum, L.tremelloides var. azureum, L. Victorianum, 
and Z. Burgessü. It is notable that the Victorian Collemata 
belong chiefly to the narrow-spored section (Synechoblastus) of 
that genus, which is usually the least numerous. 
2. LICHINA CONFINIS, Ach. 
Frequens supra scopulos maritimos ad mare Australe et ad 
sinum Port Phillip, aqua marinä inundata. 
3. SYNALISSA MICROCOCCA, Born. et Nyl. 
Abundans supra muscos et rupes subalpinos in Mt. Macedon 
(alt. 3400 ped.). 
4. COLLEMA PLUMBEUM, F. Wils.,sp. nov. (Pl. XLIX. fig. 2.) 
Thallus plumbeus parvus complicatus membranaceus rotundo- 
lobatus, lobis undulatis. Apothecia minuta sæpe conferta rufo-
