﻿ON SCHWEINITZ'S SYNOPSIS FUNGORUM. 211 



in its rhubarb-colored substance and minute pores ; and in the latter character it 

 differs also from P. dryophilus, Berk. The Schweinitzian plant is, as we believe, 

 only a form of P. scrwposus. Specimens exactly similar were gathered by Mr. Lea 

 in Ohio. 



409. P. lobatus, Schwein. This is one of the specimens missing from the Herba- 

 rium. It must be very different from the Friesian homonym. 



410. P. Pini Canadensis, Schwein. ! Certainly the same with P. hi/pococcinus, 

 Berk. See above, No. 370. 



411. P. spongiosus, Fr. The plant of Fries is a resupinate form of P. nidulans, 

 such as occurs in Scotland, which this certainly is not. The pores are too large to 

 allow of its being a state of P. igniarius, but our materials are scarcely sufficient for 

 arriving at an}' distinct opinion. P. spongiosus, Klotsch, Herb. viv. Mye. No. 2, is 

 the same production. 



414. P. ferruginosus, Fr. 



416. P. salicinus, Fr. 



417. P. subspadiceus, Fr. We are unacquainted with the Friesian species. 



418. P. spissus, Schwein. This species, of which there are authentic specimens 

 in Hook. Herb., is totally different from the Friesian plant, which we believe that 

 we have from S. Carolina. The pores have the same resinous appearance as in P. 

 Pilotce, Schwein. In the Schweinitzian Herbarium it is marked P. rufus. 



419. P. unbatus, P. This differs from the plant of Persoon, of which we have an 

 authentic fragment, in the far larger pores. In color it agrees with it. 



420. P. Nieskyensis, P. 



421. P. umbrinus, P. Certainly not the same with P. obliquus. We cannot 

 distinguish it from P. ferruginosus. 



422. P. Juglandinus, Schwein. ! Certainly different from P. spissus of Hook. Herb. 



423. P. viticola, Schwein. ! Resembles P. contiguus, and perhaps not really 

 different, though totally distinct from P. super facialis. 



424. P. xanthus, Fr. Totally different from authentic specimens of the Friesian 

 species, but exactly agreeing with a specimen under the same name from Desmazieres, 

 except that it is not at present stratose. It somewhat resembles resupinate forms of 

 P. annosns, except that the pores are smaller We have the true P. xanthus from 

 S. Carolina.
