conspicuous but thin, white, persisting in dried specimens ; tubes 

 2 to 4 mm long, their mouths white (fide Peck), more or less cinna- 

 mon buff or clay color in herbarium specimens, suffused with a 

 grayish pruinosity easily rubbed off when fresh, angular, rather 

 thick-walled, entire, averaging 5 to 7 to a millimeter ; spores allan- 

 toid or cylindric, hyaline, 3 to 4x1 fi; basidia 2 /a in diameter ; 

 cystidia none; trama very compact, composed of flexuous, nearly 

 simple, hyaline hyphae, 3 to 7 ^ in diameter, apparently without 

 cross walls ; no clamp connections. 



On decorticated trunks of spruce.

Original description. Effused, i to 2 lines thick, somewhat 

 tenacious, adnate or inseparable from the matrix, white, the sur- 

 face slightly undulate or uneven, the margin definite, studded with 

 drops of moisture when fresh, spotted with dotlike depressions 

 when dry; pores subrotund, minute unequal, often oblique. 



Decaying prostrate trunks of deciduous trees. Osceola. 

 August. 



This species is at once distinguished by its adnate subiculum and 

 its peculiarly spotted margin. The spots are watery white in the 

 fresh state and each one is covered by a drop of moisture. In the 

 dried plant the place previously occupied by the drop of moisture 

 becomes a small depression in the subiculum. 



Notes. The type collection contains but a moderate amount of 

 material at present, but apparently enough to exhibit the important 

 characteristics of the species. The largest and best developed speci- 

 men is only about 10 cm long and 5 cm broad, but the fungus 

 probably occurs more widely effused. Peck describes it as " adnate 

 or inseparable from the matrix " but inspection of the lower sur- 

 face of the plants shows a smooith surface where it has been in 

 contact with the substratum. In this respect it has the appearance 

 of Poria subacida when growing on a smooth surface, and 

 that species under such conditions is separable. The hymenial
