Few cross walls and clamp connections are recognizable on these 

 hyphae The hvphae of the sterile margin and subiculum are 

 somewhat different, being long and straight, simple or nifre- 

 quently branched, and with abundant and conspicuous clamp con- 

 nections (plate 22, figure 3). Cross walls are apparent only where 

 clamp connections are present. The diameter of both types of 

 hvphae is quite small, up to 2.5 /x. 

 'in general appearance the species bears some resemblance to 

 P o r i a s e m i t i n c t a and to resupinate forms of P o 1 y - 

 porus semipileatus Peck. But from both it differs m 

 the much smaller diameter of the hyphae, and from the former 

 also in the considerably smaller tubes. 



Redescripfwn. Effused for several centimeters, annual, sep- 

 arable (?), verv thin, light of color, with a narrow, sterile pubes- 

 cent, white margin at least when young; subiculum very thin and 

 inconspicuous, white; tubes up to .75 mm in length, their mouths 

 lic^ht buff or pinkish buff, rounded, averaging 5 to 6 to a millimeter, 

 the dissepiments relatively thick, slightly pubescent when young, 

 quite even and entire; spores cylindric or allantoid, hyaline, 3 to 

 5 X I to 2 ^; cystidia none; trama of loosely arranged, hyaline, 

 thin-walled, flexuous hyphae, sometimes branched, cross walls and 

 clamp connections, not often apparent; subiculum hyphae straight, 

 simple, with conspicuous clamp connections at the cross walls; 

 diameter of both types i to 2.5 ix.

44th Rep't N. Y. State Mus., p. 21. 1891 

 Original description. Resupinate, effused or nodulose, pale 

 sulphur-yellow ; pores short, labyrinthiform, the dissepiments often 



lacerated and irpiciform in the dry plant; spores subglobose or 



broadly elliptical, .0002 in. long. 



Much decaved wood. Salamanca. September. 



Mostly very irregular or nodulose, following the irregularities 



of the wood^ and encrusting mosses. It is of a beautiful pale 



yellow color when fresh, but it changes to a dull pallid hue when 



dry.
