SPORES HYALINE. 



POLYPORUS FLORIFORMIS. Pileus thin, white, smooth 

 usually reduced at the base, unchanged in drying. Flesh thin, 1-2 mm , 

 stiptic to taste. Pores small, round, or slightly elongated, pure white! 

 2-4 mic. long. Spores 3x4 mic., opaque. 



This is a thin, white species, growing imbricate and pilei reduced 

 at the base, hence might be sought in Petaloides. It is rare both in 

 Europe and United States, and grows on acerous wood. It was well 

 illustrated by Bresadola (t. 63), who really named the plant, although 

 they write Quelet after it. It has a stiptic taste, and one of my cor- 

 respondents holds it to be Polyporus stipticus.

Polyporus undosus. 



POLYPORUS LACTEUS (Fig. 656). Pileus effuso-reflexed, 

 white, rather thin, with rugulose, undulate surface. Flesh white, soft, 

 friable. Pores small, round, thin, but on the effused portion elongated, 

 unequal, angular. Spores 1^x4-5 mic., allantoid. 



This to me is a rare plant, and so stated by Fries. I have but one 

 collection from Otto Jaap, Germany, which grew on poplar. There 

 is a poor cotype at Kew which I have compared with Jaap's collection 

 and found to be the same. It has the same flesh, surface, and spores 

 as Polyporus trabeus (compare page 301), but is a thin plant, largely 

 effusive behind, with the pores on the resupinate portion elongated 

 and angular. I believe it is too close to Polyporus trabeus, but in my 

 view it is not Polyporus trabeus of Fries; and the Fries' view is "Law" 

 nowadays. 



SPECIMENS. Only one, from Otto Jaap, Germany.
