On dead tnmks and branches. Northern Island, New Zea- 

 land. Victoria, Queensland, Western Australia, Malacca, Ceylon, 

 Europe, North America. 



Often broadly efiused, or almost entirely covering fal'en 

 branches, inseparable from the matrix ; flesh almost none ; 

 pores very variable, large, angular, or sinuous ; often irregularly 

 torn and more or less oblique, appearing as if sunk in the matrix, 

 which is usually bark, whitish or pallid, becoming pale-ochra- 

 ceous when dry. Pores often reaching 1 mm. in diameter. 

 This species is sometimes destructive to worked wood, forming 

 a white, spreading mycelium resembling the early stage of " dry 

 rot." 



Poria mollusca, Fries, Syst. Myc, i, p. 384 ; Sacc, Syll. vi, 

 no. 5936 ; Austr. Fung., p. 153. 



Efiused, thin, soft, white, margin fibrillose and giving ofi 

 radiating strands ; pores very shallow, minute, angular, dis- 

 sepiments very thin and unequally torn, occupying the central 

 portion of the patch, or scattered here and there in groups, 

 \-\ mm. diameter. 



On rotten wood, and on heaps of dead leaves. New Zealand. 

 Victoria, Europe, United States. 



Sometimes broadly efiused ; known by the fringed fibrillose 

 margin ; the partitions of the pores are very thin, and usually 

 toothed or torn. Sometimes tinged with yellow. At first form- 

 ing a mere byssoid margin, which gradually acquires moderate, 

 rigid, subrotund and angular pores. 



Poria hyalina. Berk., in Hooker's Flora Tasm., ii, p. 255 (1860) ; 

 Sacc, Syll. vi, no. 5938 ; Cooke, Austr. Fung., p. 153. 



Resupinate, very thin, white, more or less hyaline, circum- 

 ference sterile, membranaceous, margin not byssoid ; pores 

 very shallow, irregular in form, ^— | mm., dissepiments very 

 thin. 



On dead wood. New Zealand. Tasmania. 



Very delicate, not thicker than paper ; hymenium becom- 

 ing much cracked, due to shrinkage during drying. The some- 

 what broad sterile border remains firmly attached to the matrix. 



Poria leucoplaca. Berk., Fl. N.Z., ii, p. 180 ; Hdbk. N.Z. Flora, 

 p. 609 ; Sacc, Syll. vi, no. 6092. 



Entirely pure white, resupinate, thin ; following the irregu- 

 larities of the matrix, margin distinctly defined, every part 

 covered by the small pores about ^ mm. diameter, dissepi- 

 ments rather thick, edge pulverulent under a lens ; flesh almost 

 none.
