On branches. Northern Island, New Zealand. Queensland. 



This species was at first incorrectly determined as Aleuro- 

 discus oakesii. The last-named is not known to occur in New 

 Zealand. 



Corticium scutellare. Berk, and Curt., Grev., ii. p. 4 ; Brit. Fung. 

 FL, i, p. 121 ; Sacc, Syll. vi, no. 7647. 



Broadly effused, thin, quite inseparable from the matrix, 

 margin indistinct, whitish, then dirty pale-tan-colour or tawny, 

 waxy, smooth, very much cracked into polygonal portions, 

 interstices white, silky ; spores elliptical, 5 x 3 /x. 



On wood, dead herbaceous stems, &c. Recognised by the 

 brownish areolately cracked hymenium, and small spores. 



Corticium leve, Pers., Disp., p. 30 ; Sacc, Svll. vi, no. 7530 ; 

 Cooke, Austr. Fung., p. 194; Fl. N.Z., ii. p. 184; Hdbk. 

 N.Z. Flora, p. 613. 



Forming very thin patches from 5-10 cm. in diameter ; 

 hymenium smooth and with a more or less polished appearance,, 

 old-ivory colour often suffused with a flesh-colour or rosy tinge, 

 becoming cracked when dry, the interstices silky, margin bys- 

 soid ; spores elliptical, often slightly curved, 10-12 x 6-7 //. 



On dead wood and bark. Northern Island, New Zealand. 

 Victoria, Queensland, Tasmania, Ceylon, Europe, North and 

 South America. 



Some forms of this species closely resemble, superficially, 

 Penio'phora rosea, but can at once be recognised under the micro- 

 scope, or even under a pocket-lens, by the absence of projecting 

 cystidia in the hymenium. 



*** Hymenium, tinged green. 



Corticium viride. Berk., Fl. N.Z., ii, p*. 184 ; Hdbk. N.Z. Flora, 

 p. 613. 



Olive-green, crustaceous, effused, cracked ; margin very thin, 

 membranous, scarcely byssoid, livid ; spores large, elliptic or 

 subglobose. 



On dead bark and wood. Northern Island, New Zealand. 



Effused, forming small confluent patches of a yellow oliva- 

 ceous green, with a very thin, membranous, scarcely byssoid, 

 livid margin ; hymenium cracked ; spores subglobose or elliptic, 

 very large Yy^g^jin. long (= about 14 /x). Analogous to Hydnum 

 viride. When old it acquires a darker tinge. There is no 

 specimen of this species at Kew.
