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) 
Polyporus caeruleoporus Peck, Rep. N. Y. State Mus. 26: 68. 
1874. 
Exsicc.: New York, 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 are fulvous with darker hy- 
menium and ochraceous flesh. How long the grayish-blue color 
remains after drying I cannot tell. 
7. Scutiger holocyaneus (Atk.) 
Polyporus 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.
