and " aniline black " has too much purple in it to represent Peck's 

 types. 



Redescription. Effused for several centimeters, annual, rather 

 tender, separable, with a thin whitish or yellowish sterile margin 

 when young; subiculum very thin, whitish, rather conspicuous-, 

 tubes 2 to 6 mm long, their mouths dingy whitish (fide Peck) when 

 fresh, becoming darker where bruised or dried, fuscous or bister in 

 herbarium specimens, angular, thin-walled but entire, averaging 1.5 

 to 2 to a millimeter; spores ellipsoidal or ovoid, smooth, fuscous, 

 7.5 to II X 4 to 7 /x; cystidia none; trama and subiculum compact, 

 of thin-walled, partially collapsing and irregular hyaline h}phae 

 with inconspicuous cross walls and clamp connections, nearly 

 simple, 1-3 fi in diameter.

Original description. Resupinate, effused, thin, soft, tender, 

 orange-yellow;, the mycelium creeping in and over the wood, silky- 

 tomentose, at first white, then yellow, forming' numerous yellow 

 branching rootlike strings or ribs which are more or less connected 

 by a soft silky tomentum ; pores rather large, angular, at first shal- 

 low, sunk in the mycelium, the dissepiments becoming more elevated, 

 thin and fragile ; spores elliptical, .0002 to .00025 inch long, .00016 

 broad.

The species is allied to P. vaillantii, in its peculiar 

 rhizomorphoid strings of nnxelium, but from this it differs decid- 

 edly in its color and texture. In these respects it approaches P . 

 b o m b y c i n u s , of which it may possibly be a peculiar variety. 

 It is very destructive to the wood on which it grows, causing it to 

 become soft, brittle and even friable. 



Notes. From the standpoint of the type collection this species is 

 the most unsatisfactor\- of all of Peck's Porias. Nothing as to 

 general appearance, color etc., can be added beyond that contained
