Polyporus sulphureus. So called for many years and much the best 

 name that can be applied to It. Common, late in the season. 



Polystictus conchifer. A most peculiar species, named by Schweinitz. 

 It occurs only on elm, and does not grow in Europe. 



Polystictus hirsutus. A very common and a very variable plant. Around 

 Cincinnati it is quite uniform, but many forms (?) reach me, an,d I do not 

 know but that I am confusing more than one species. 



Polystictus perennis. A frequent species growing in the ground. A 

 form in the Southern States has larger pores, and is known as Polystictus 

 parvulus. I doubt if it can be kept distinct. 



Polystictus pergameus*. A very common plant in the United States, 

 usually growing on oak. It is claimed that as the original grew on pine it 

 is not the same as the common species in the United States, and the name 

 Polystictus pseudo-pergameus has been proposed. However, the plant is 

 generally known as Polystictus pergameus. It is a curious fact that this is 

 a very rare plant in Europe, and it was recently brought into the museum 

 at Paris as a great rarity. It is called in France "Polystictus simulans, 

 Blonski." 



Polystictus sangulneus. This is the bright-red species of the Southern 

 States, and is close to Trametes cinnabarinus (which see). It is common 

 throughout the warm regions of the world. 



Polystictus versicolor. The most frequent Polystictus that occurs and 

 the most variable. New species hunters are wasting their opportunities. I 

 They should devote themselves to this plant, for they can make a "new 

 species" out of every specimen they collect. 



Trametes cinnabarinus. The only red polyporoid in the northern United 

 States. It is a question whether it should be called Trametes or Polystictus, 

 and it is given both names in Saccardo. (Cfr. Polystictus sanguineus.) 



Schizophyllum commune. A very common species all over the world 

 and in every country, hot and cold, where I have ever been. At Cincin- 

 nati it has a special liking for the maple. It has been known as "commune" 

 for two generations, but recent date dictionary investigators have called it 

 Schizophyllum .alneum, in my opinion a stupid change for a plant that is 

 the most common species, that occurs everywhere, and grows in many 

 countries and thousands of localities where alder does not grow. 



Stereum albobadium. A very common plant at Cincinnati, but does not 

 occur in Europe, I think. The margin is generally so slightly recurved it is 

 more liable to be taken for a Corticium. 



Stereum frustulosum. If this plant does not have another generic name 

 it ought to have. One who is familiar with other stereums would never sus- 

 'pect its relation to that genus. 



Stereum ochraceoflavum. It is of a Southern type. Common in Florida, 

 but I have received it from New Jersey and once from Connecticut. 



Stereum versicolor. As I have always known the plant and as it is gen- . 

 erally known. I think Professor Burt told me he had decided to c:ill it 

 another name, but I have forgotten what it is.
