Out of 76 British we have 38 species. 



Genus 21. Trametes.* 

 Trama descending among the pores, but remaining quite un- 

 changed ; pores concrete with the pileus, and entire. 



Fries has separated some of the Polypori, as P. Versicolor for 

 instance, from the rest under the generic name of Polystictus, the 

 character being that the pores, which are developed in a centri- 

 fugal direction, are perpendicular to the fibrillose stratum above 

 the hymenophore. In Trametes the hymenophore is not distinct 

 from the rest of the pileus. 



Trametes Odora, Fr. Bolt., t, 162. On willows ; common. 



• Trametes, from tramis, the space between the poros of a Polyporus.
