\Polyporus. 
small, punctiform ; dissepiments thick, with flattened obtuse pulverulent 
edges. 
Northern Island : on sticks, Colenso. 
24. P. (Resupinatus) diffusus, Berk. in FI. N. Z. ii. 180. Bright 
red, effuse, at length tearing away from the matrix, and leaving part of its 
substance behind. Pores small ; edges thin, membranous, slightly toothed. 
Northern Island : on charred wood, Colenso. Probably an imperfect form. 
25. P. (Resupinatus) vaporarius, Fries ; — Berk, in FI. N. Z. ii. 
180. Firm, persistent, with difficulty torn away, thin, dry, whitish; myce- 
lium creeping in the tissue of the wood. Pores large, angular, white, 
crowded into a close firm persistent stratum ; edges torn. — Berk. Outlines, 
252. 
Northern Island: on dead wood, Colenso. (Europe, Tasmania.) 
11. D JED ALE A, Persoon. 
Habits of Polyporus. Hymenophorum descending unchanged into the 
trama. Pores, when fully formed, torn, toothed or labyrinthiform. 
A large genus, both tropical and temperate. 
1. D. confragosa, Pers.; — FI. N~. Z. ii. 180. Stem 0. Pileus be- 
tween corky and coriaceous, somewhat zoned, scabrous, brownish-red, sub-

more that of a Radulum. 
12. FAVOLUS, Fries. 
Plabit of Polyporus. Pileus fleshy, flexible. Hymenium reticulated, cel- 
lular, alveolate. Pores radiating, elongated, formed by densely anastomosing 
laminae with double walls. 
A small tropical genus, allied closely to Polyporus , hut the pores are large from the first, 
not minute and afterwards dilating. 
1. F. intestinalis, Berk, in Plook. Kew Journ.Bot. iii. 167 ; FI. N. Z. 
ii. 181. White, turning olive- or dirty yellow in drying. Pileus thin, soft,
