nearly flat, varying from pale-ochraceous through reddish -brown 

 to umber, with very dehcate lines radiating from the point of 

 attachment to the margin, other\vise glabrous, 3-8 cm. broad ; 

 pores rather large, irregular, coloured like the pileus ; stem 

 usually lateral, very short-, 3-4 mm. long by 2-3 mm. thick, 

 scarcely discoid, sometimes quite central, at others almost 

 absent. 



On rotten trunks, fallen wood, &c. New Zealand. Queens- 

 land, New South Wales. New Guinea. 



A verv variable species in minor points, but characterized 

 by the thin flesh, very short lateral stem, and the pileus streaked 

 with very delicate, crowded, radiating ridges.

Horizontal, subspathulate or reniform, either narrowed 

 behind into a short more or less distinct stem, or thick and 

 sessile, 4-10 cm. across, whitish then dingy-yellow, spongy then 

 €orky, compact, hairy ; flesh thick, whitish, composed of parallel 

 fibres; tubes 5-8 mm. long; pores unequal, flexuous ; dissepi- 

 ments thin, white, torn ; spores hyaline, snbglobose, 4 fi diameter. 



On stumps and trunks of conifers, &c. Otago, Middle 

 Island, New Zealand. Asiatic Siberia, Europe, United States. 



Pileus often radiately \mnkled, rigid and more or less in- 

 curv'ed when dry. AMien a stem is present the pores are more 

 or less decurrent. Fleshy wheu young, becoming cork}' with age.

Main branches numerous, rather slender, springing from a 

 common basal mass, and dividing into many smaller branch- 

 lets, each terminated by a small, fan-shaped, depressed pileus, 

 broAvnish, nearly smooth ; hymenium pale ; pores shallow, large, 

 often elongated, decurrent ; dissepiments thin, edge acute, 

 often toothed. 



On tnmks. Tarawera, Northern Island, New Zealand. 



" Forming a mass more than 1 ft. across ; main stems slender, 

 distinct, somewhat elongated, repeatedly dichotombus. Pilei 

 extremely numerous, flabelliform, expanded, depressed above, 

 bro\vnish, smooth, or nearly so, with a few raised lines. Pores 

 pale, often very much elongated, decurrent ; dissepiments 

 thin ; edge extremely acute, often toothed, sublamelUform. 

 This is a noble species, and evidently differing from every form 

 of P. intyhaceus in its distinct dichotomous branches and the 

 constantly acute dissepiments. Some of the figures of Hydnum
