POLYPOREI. 



Dsedalea. On dead wood. Rare. 



Name latus, broad. Very broad. Fr. Hym. Eur. p. 589. Syst. Myc. \, 

 p. 340. Berk. Out. p. 254. C. Hbk. n. 828. S. Mycol. Scot. n. 781. 



7. D. vermicularis Pers. Flesh- colour -rufesce?it, broadly 

 effused, thin, becoming even ; sinuses short, attenuated at both 

 ends, flexuous, poriform at the margin. 



It has much in common with D. latissima, but is much thinner, 10-15 cent. 

 (4-6 in.) long, 5 cent. (2 in.) broad. Adhering to the soil by root-like fibres. 



On the ground. 



Berkeley refers the figure of Sowerby to D. latissima. Name vermis, a 

 worm. From the peculiar colour. Pers. Myc. Eur. 3. p. 2. Fr. Hym. Eur. 

 p. 589. Sow. t. 424. 



Species of tine er tain affinity. 



8. D. ferruginea Schum. Pileus light-yellow -ferruginous, 

 white-villous when young and at the margin, internally flesh- 

 colour, coriaceous, effuso-reflexed, zoned; hymenium porous 

 then narrowly labyrinthiform, tawny. 



Imbricato-connate. It seems nearest to D. unicolor. 

 On dead wood. Strachan, Kincardineshire. 



Name -ferrum, iron. 

 S. Mycol. Scot. n. 782. 



Ferruginous. Schum. Fr. Hym. Eur. p. 589. 

 Fl. Dan. t. 2029. 



Hexagona. GENUS XXVII. Hexagona (hexagonum, a six-sided figure ; from 

 the form of the pores). Poll. PI. nov. p. 35. Epicr. i. p. 496. 



Hymenophore descending and forming a trama of the same 

 colour as the pileus and similar to it. Pores at the very first 

 dilated into hexagonal, regular, woody-hard alveoli, the dividing 

 walls firm, never torn. Dimidiate, sessile, growing on wood, 

 corky-woody, persistent, but not growing again to form strata. 



A very natural genus, easily recognised. The essential feature 

 consists in the depressions being equally wide in the earliest 

 stage of growth, whereas in the Polypori the pores, which are 

 minute when young, are gradually developed and dilated. Fr. 

 Hym. Eur. p. 589. 



No British species.
