Murrii-l: Polyporaceae of North America 429 



November, 1895, and now in the Underwood herbarium. Al- 

 though the description is on this account unsatisfactory, the plant 

 is nevertheless very distinct and must be highly attractive when 

 seen at its best. The only other plant of this species that I have 

 seen is one at Kew sent by Ravenel under the name P. confluens. 

 This specimen however, does not figure in my description, since I 

 have made no special study of it. Like most of the other mem- 

 bers of the genus, this species is doubtless rare and probably con- 

 fined to the states south of Virginia. The appearance of the stipe 

 indicates that it is terrestrial, growing unattached in soil rich in 

 humus. The name I have chosen for it refers to its brilliant color- 

 ing throughout. 



6. Scutiger caeruleoporus (Peck) 

 Poly poms caeruleoporus Peck, Rep. N. Y. State Mus. 26 : 68. 



1874. 



Exsicc. : New NoxV, Peck, Ellis; Vermont, Morgan; North 

 Carolina, Atkinson. 



This rare and beautiful species is found on the ground in woods 

 during midsummer. In sheltered spots the whole plant is exter- 

 nally grayish-blue in color, the blue fading gradually to gray upon 

 exposure. Specimens have been found with one half of the pileus 

 exposed and faded, while the other sheltered half was normal. In 

 drying, the blue color disappears, being retained longer in the 

 hymenium than in the surface of the pileus. It was from par- 

 tially faded specimens that the plant was first described. Herba- 

 rium specimens in the Ellis collection arc fulvous with darker hy- 

 menium and ochraceous flesh. How long the grayish-blue color 

 remains after drying I cannot tell. 



7. Scutiger holocyaneus (Atk.) 

 Polyponis holocyaneus Atk. Jour. Myc. 8: 117. 1902. 

 This species was collected near Blowing Rock, North Caro- 

 lina, by Atkinson and Troyer in September, 1901. Several plants 

 were found growing gregariously on the ground beneath coniferous 

 trees. When fresh they were entirely blue, but in drying the color 

 changed to dull brown. In this and several other respects the 

 species resembles Scutiger caeruleoporus, from which, however, it 

 is quite distinct.
