were seen attached to these basidia. In other cases, however, 

 hyphae were seen to give off a number of upright branches, closely 

 arranged, and each terminating in a basidium. The tramal and 

 subiculum tissue is fairly compact and is made up of hyphae that 

 vary considerably in size. Some are 5 to 7.5 /x in diameter and com- 

 posed of short cells 25 to 50 fi long (plate 6, figure i, 3). For the 

 most part they are slightly encrusted with small scattered crystals. 

 Other hyphae, especially in the trama, are considerably smaller, 

 with a diameter of 2.5 to 5 ;u, (plate 6, figure 2). Hyphal fusions 

 are common in hyphae of both sizes. There are no cystidia in the 

 hymenium. No clamp connections have been observed. 



The species is quite distinct from any other of Peck's species in 

 the very thin fructification, and the presence of the large hyphae, 

 sparingly encrusted and composed of short, loosely joined cells. 



The specimens are from very rotten spruce wood and nothing can 

 be determined as to the type of decay produced. 



Redescript'wn. Annual, not widely effused, .5 to 4 cm in diameter, 

 inseparable (fide Peck, though with appearance as if it might be 

 separable), fertile to the margin; subiculum not visible in herbarium 

 specimens ; tubes less than .25 mm long, their mouths grayish white 

 (fide Peck) in fresh specimens, pale smoke gray to pinkish buff or 

 cinnamon buff in herbarium specimens, circular, thin-walled, entire, 

 averaging 4 to 6 to a millimeter; spores hyaline, oblong or short 

 cylindrical, sometimes curved, often pointed at the base, 4 to 5 x i 

 to 2 fji] basidia 2 to 3 /u, in diameter; tramal and subiculum tissue 

 compact, some hyphae 5 to 7.5 /n in diameter and of short cells 25 to 

 50 fjL long, others 2.5 to 5 /a in diameter and of longer cells, both 

 kinds much branched, frequently anastomosing, and usually slightly 

 encrusted with a few scattered crystals; clamp connections absent.
