2. G. 2)hoeocephalum, Borr. var. phfjedrosporurii, Wilson. 



Tballus white, or whitish, witli pale glauceseent venucose 

 congested granules, which are sometimes dissolved into 

 citrine soredia. Apothecia atro-fuscous, with slender stipe 

 (about "2 mm. high, -1 mm. thick), the upper ]>art citrino 

 suffused ; capitulum hemispherico-turbinate or sub-globose ; 

 margin citrino suffused ; sporal mass from fulvous to 

 umbrine. Spores dilutely nigrescent, very nearly colourless, 

 <lelimitated by a dark line ; form variable, globose or 

 ellipsoid, simple, nucleated, diameter -002 to "004 mm. 



Hab. on decaying decorticated eucalyptus, near Kilmore. 



I am doubtful whether the granules of the tballus belong 

 to this liclien, or are au undeveloped form of some other. 

 Perhaps the plant is of a new species, which may be called 

 C. phmdrosporurti. 



3. C. nivewni; Wilson. 



Thallus snowy white, thick, or cinerascenti albid, thinner, 

 effuse, rimulose with convex areolse. Apothecia minute 

 (•5 to '8 mm. high), stipe slender (-07 mm. thick), either all 

 whitish or partly hyaline and partly fuscous, or all fuscous, 

 or ail black, sometimes furcate. Capitulum hemispherico 

 lenticular, black, about "25 mm. broad, sometimes divided 

 into two or three or more lobes. Spores dilutely nigrescent, 

 fusiformi ellipsoid, or oblong, compressed, simple, ■004' to 

 •006 X -002 to 0025 mm., paries thick. Gel. hym. with 

 iodine vinous yellow. 



Hab. on dead bark of living eucalyptus, Cunninghame, 

 Maffra, Beechworth. 



Perhaps a variety of 0. pusiolum, Ach.
