ON POLYPORUS PULCHERRIMUS. 

 By L. Rodway, C.M.G. 



(Read 10th October, 1921.) 



Polyporus pulcherrhmis , n.s. Dimidiate sessile, simple 

 bracket or irregularly proliferate, generally about 10 cm. 

 diameter, bright crimson throughout, fleshy, very watery, the 

 dorsal surface roughly verrucose-strigose with no distinct 

 dermis. Pores very irregular mostly about one millimetre 

 diameter, dissepiments very thin and irregular at the mouth. 

 Spores hyaline, very broadly oblong, 6 x 5 m diameter. 



Commonly on the trunk of our Evergreen Beech, rarely 

 on a Eucalypt. It is a wound parasite, but spreads to the 

 living wood. Mr. C. G. Lloyd, to whom I submitted this 

 fungus, points out the close relationship to Polyporus con- 

 fluens, from which it differs in the absence of a differentiated 

 dermis, crimson colour, growing on trees, more watery con- 

 sistency, and rather larger oblong spores.
