scaly, owing to the rupture of the cuticle; margin white, sterile, 

 entire, involute when young; context sulfur-yellow, unchanging 

 or turning slightly yellowish-green when cut, with pleasant odor 

 and mild flavor; tubes large, decurrent, elongate near the stipe, 

 flavous when young, dark dirty-flavous with a greenish tint when 

 older, unchanging when bruised ; spores oblong-ellipsoid, smooth, 

 yellowish-brown, 8.5-10.5 X 3-5fi ; stipe subequal, 7X2 cm., 

 flavous at the apex, then testaceous, then adorned with the ample, 

 white, persistent, cottony annulus, and below this similar to the 

 pileus in color and surface markings. 



This species is similar to B. luteus and takes its place in the 

 flora of the Pacific Coast; but the tubes are larger and the sur- 

 face is floccose-scaly. At Corvallis it was very abundant in fir 

 woods mixed with a few deciduous trees. It gives me pleasure 

 to dedicate this handsome species to Professor E. R. Lake, of 

 the Oregon Agricultural College, who some time ago sent me 

 specimens for determination collected by him at Corvallis, No- 

 vember 29, 1907. This type collection was accompanied by notes 

 and an excellent photograph.

Certomyces communis (Bull.) Murrill. Common about Seattle, 

 but rare in other localities. Several varieties were found.

Ceriomyces mirabilis sp. nov. 



Pileus convex, spongy, solitary or gregarious, reaching 12 cm. 

 in diameter; surface moist, bay, uniformily covered with con- 

 spicuous, projecting, conic, floccose, persistent papillae, which 

 give it somewhat the appearance of bread-fruit; margin project- 

 ing like the eaves of a house, showing a yellow membrane 2-3 

 mm. wide; context citrinous, slowly changing to incarnate when 

 bruised, very watery, drying with difficulty, tasteless ; tubes large, 

 greenish-yellow, uneven; spores fusiform, smooth, ochraceous- 

 mellous, 19X7 /a; stipe very bulbous, solid, bay and streaked 

 below, strongly reticulate and latericeous above, the apex colored 

 like the tubes, 15 cm. long, 1.3 cm. thick above, 3.5 thick below. 



This remarkable species was found several times in the vicinity 

 of Seattle on the ground in woods. It is one of the most difficult
