FLORA OF NEW ZEALAND. 



[Fungi, 



elongated into a short stem, extremely smooth, marked with little waved furrows ; cuticle cartilaginous and subtrans- 

 lucent when dry. Pores very minute, just visible to the naked eye, irregular ; dissepiments very thin, denticulated, 

 sometimes tomentose. — A very distinct species, somewhat resembling P. liturarius, Berk, et Curt., gathered at the 

 Feejee Islands by the American Antarctic Expedition, but more nearly allied to the subarctic species P. obductus, 

 Berk. — Plate CV. Eig. 3, P. phlebophorus, Berk., natural size. 



4. Polyporus (Pleuropus) xerophyllus, Berk. ; pileo flabellato suborbiculari radiato-rugoso scabriusculo, 

 margine crenato, stipite brevi nigro ruguloso subtiliter velutino, hymenio pallido, poris parvis, acie obtu- 

 siuscula. (Tab. CV. Pig. 2.) 



Hab. On dead wood, Colenso. 



Pileus about one inch across, flabelliform, suborbicular, brown with a strong rufous tinge, marked with raised 

 radiating lines, and many smaller wrinkles, very minutely scabrous; margin thin, crenate. Stem -| of an inch long, 

 black, rugose, most minutely velvety. Hymenium nearly white. Pores just visible to the naked eye ; dissepiments 

 varying in thickness ; edge generally rather obtuse. — A very neat little species, closely allied to P. varius, but more 

 particularly to P. grammocepkalus, from which however it differs in the rugged, differently coloured pileus. — Plate 

 CV. Fig. 2, P. xerophyllus, Berk., natural size. 



5. Polypoms luoidus, Pr. Fp.p. 442. 

 Hab. On dead wood, Colenso.

7. Polyporus (Merisma) Colensoi, Berk. ; rarnosissimus, frequenter dichotomus, pileis parvis flabellifor- 

 mibus lineatis glabris, poris elongatis, dissepimentis tenuibus, acie acutissima. 



Hab. On trunks of trees in forests : Tehawera, Colenso. 



Forming a mass more than a foot across ; main stems slender, distinct, somewhat elongated, repeatedly dicho- 

 tomous. Pilei extremely numerous, flabelliform, expanded, depressed above, brownish, smooth, or nearly so, with a 

 few raised lines. Pores pale, often very much elongated, decurrent ; dissepiments thin ; edge extremely acute, 

 often toothed, sublamellasform. — This is a noble species, and evidently differing from every form of P. intybaceus 

 in its distinct dichotomous branches, and the constantly acute dissepiments. Some of the figures of Hydrmm 

 eoralloides give a better idea of the ramification of the species than any of those of P.frondosus.

8. Polyporus dichrous, Pr. Ep.p. 457. 



Hab. On dead wood, Tehawera, Colenso, J. B. II. 



The specimens are more undulated than usual, but cannot be separated from the more ordinary form. P. nigro- 

 purpurascens, Schweinitz, scarcely differs.

10. Polyporus isidioides, Berk, in Hook. Fond. J. Bot. v. 2. p. 415. 

 Hab. Bay of Islands, /. B. II. 



This is a common Polyporus in the southern hemisphere, and perhaps may prove eventually a subspecies of 

 P. scruposus, Fr.
