THE VICTORIAN NATURALIST. 65 



to 75 mm. high ; stipe 'i mm. thick. Capitulum turbinato- 

 globose (•2--5 mm. broad), margin white. Spores fusiformi- 

 ellipsoid, somewhat pointed at each end (•oo8--oi2 mm. long, 

 •003-005 mm. broad), uniseptate, somewhat constricted at 

 septum, fuscous with a fusco-nigrescent locule in each cell. 

 Habitat on decaying decorticated eucalyptus. The apothecium 

 is like that of C. ciiitu77i, but the spores are different in shape 

 and colour, and size, and the thallus is altogether unlike.

 with thalline and other granules, i mm. high, or rather more. 

 Capitulum turbinato-lentiform attaining a diameter of "5 mm., 

 stipe -2 mm. thick. Sporal mass black, protruded, sometimes 

 extending considerably on one side. Spores fusiformi-ellipsoid, 

 nigrescent, ■oo6-'oo8 mm. long, •oo25-'oo4 mm. broad, unisep- 

 tate, septum generally rather indistinct. Habitat on decaying 

 eucalyptus. 



20. Calicium nigrum. Schser. ; var, nov. minutum, C. Knight. 

 Thallus obscurely cinereous or black, leprose. Apothecia short 



(•5 mm. high); stipes stout (•i--i2 mm. thick). Capitulum turbinato- 

 lentiform, disk puinose, "3 mm. broad. Spores nigrescent ('0075 

 mm. long, -004 mm. broad), ellipsoid, uniseptate, constricted at 

 middle, a locule in each cell. Habitat on old rails. 



21. Calicium subfile. Pers. ; var. nov. biloculare, Wilson. 

 Thallus whitish or cinerascent, thin. Apothecia all black (-8-1 



mm. high). Capitulum lentiform or sub-turbinato lentiform (■3-'4 

 mm. broad), stipe -i mm. thick. Spores fuscescent or fusco- 

 nigrescent, ellipsoid or sub-fusiformi-ellipsoid, bilocular or obso- 

 letely bilocular or simple, no visible septum (•oo5--oo7 mm. long, 

 •002 -'003 mm. broad). Paries somewhat thick. Habitat on 

 decaying eucalyptus. 



22. Calicium gracillimum. Wilson, spec. nov. 



Thallus a whitish spot. Apothecia all black (-8 mm. high). 

 Stipe very slender, about '06 mm. thick. Capitulum minute (-x 

 mm. broad), turbinato-lentiform. Spores ellipsoid or fusiformi- 

 ellipsoid, uniseptate (about •oot-"oo2 mm. long, •ooo6-'ooi mm. 

 broad). Habitat on decaying decorticated musk-tree. 



23. Calicium roseo-albidum. Wilson, spec. nov. 



Thallus roseo-albescent, thick, minuLely cancellate, chryso- 

 gonimic. Apothecia minute, wholly black. Capitulum lenticular 

 (•2 mm. broad). Stipe slender (7 mm. high, -06 broad.) Spores 

 nigrescent, oblong or oblongo-ellipsoid ("005 mm. or more in length, 

 •002--003 mm. broad), apices roundish, uniseptate. Habitat on 

 decaying decorticated eucalyptus, a great portion of which it 

 covers with a light rosy tint. When the thallus is bruised it
