 tbecia sraall, '3 to -4 mm. high ; stipe black, -1 to "2 mm. 

 high, -Oo to "1 mm. thick ; capitulum turbinate, disk flat, "1 

 to -2 mm. broad, margin cinerascent or albido cinerascent.

Hab. on decaying eucalyptus stump, near Tallarook. 



Var. 3. Clarensis, Wilson. — Thallus whitish or cinerascent, 

 of medium thickness. Apothecia black, '8 mm. high, stipe 

 •1 mm. thick, ca])itulum '3 mm. broad, turbinato lenticular, 

 margin whitish. Spores fuscous or fuscescent, ellipsoid, 

 narrow at apices, often constricted in middle, uniseptate or 

 bilocular, -00.5 to -OOS x •002 to -003.5 mm. 



Hab. on decaying decorticated eucalj'ptus, Bright, Beech- 

 worth. 



16. C. cwrtmn, Borr. 



Thallus whitish, thin or evanescent. Apothecia to 1 '8 mm. 

 high, but often much less, stipe to "2 mm. thick, capitulum 

 turbinate, to 'G mm. broad, albo suffused beneath. Sporal

Hab. on decaying dec(n-ticated eucalyptus and old hard-

17. C. tracheUintm, Ach. var. elattospo7 aiH, Wilson. 



Thallus obscurely cinerascent or albescent. Apothecia

'J'he dnnensions of the spores are half of those described 

 by Nylander. This is in Victoria the commonest species^of 

 this genus, and often grows in large patches on the trees, 

 covering man}^ square feet with abundant apothecia, some- 

 times making the tree seem as thouL;h clothed with short 

 hair.
