from //. cercosporoides, Speg., in which the hypha; are septate^ 

 and the 1-2 septate conidia are pale rose to fuliginous. 



72. Hexagonia bicolor, n.sp. 



Pileus dimidiate, about 3 cm. across, solitary, woody, yellowish 

 to brownish when young, smoky and cracked when old, the two 

 zones — yellow and black, distinct, smooth. Pores rounded to 

 polygonal, shallow towards margin, rather deep further back, 

 decurrent, cream-coloured, rather large, 2-3 mm. across. Spores 

 hyaline, elliptical, apiculate, 12-16 x 7-8)u. 



Restdown, N.S.W.; on dead wood of Eucalyptus woollsiana; 

 July, 1903 (R. T. Baker). 



The two-coloured pileus is very marked, as well as the large, 

 cream-coloured, polygonal pores. It differs from H. muelleriy 

 Berk., also found on Eiicaly2)tus, which is thin and rigid, and 

 the pores are only ^ mm. diam. It is rather interesting to note 

 that this seems to be the first time in w^hich the spores of this 

 genus have been recorded. Of the 88 species given in Saccardo's 

 ' Sylloge Fungorum,' in not a single instance have the spores 

 been seen or at least recorded. 



73. HUMARIA BAKERI, n.sp. 



Loosely gregarious, subsessile to distinctly stalked, glabrous, 

 all of one colour, pale fleshy pink, firm and hard; disc globose or 

 elliptic, slightly concave, about 1 mm. across. Asci cylindrical, 

 but tapering slightly towards base, rounded at apex, 8-spored, 

 85-95 X 7/x; paraphyses numerous, hyaline, septate, often bifur- 

 cating at apex. Spores 1 -seriate, hyaline, somewhat fusiform, 

 smooth, 13-16 X ^-b^x. 



Wentworth Falls, N.S.W.; on gritty soil; August, 1903 (R. 

 T. Baker). 



This is a very characteristic species with its delicate pinkish 

 tint, minute size, and subsessile to shortly stalked ascophore. 



It dijffers from H. sabnonicolor, Sacc, in the smaller size of the 

 disc and spores, and from H. novo-zelandica, Henn., in which the 

 disc is externally tomentose, the asci about twice the length, and 

 the spores larger.
