narrow, strong, darker zones. Context tissue brown. Hymenial 

 layer white, distinct from the context layer, and often but partially 

 developed over the surface. Basidia clavate, forming a palisade 

 layer. Cystidia none. Spores 3x5, hyaline, smooth. 



Stereum with smooth pilei are very rare. In fact, we know but 

 one other well authenticated, viz., Stereum versicolor, in its true 

 sense. (Cfr. Note 53, Letter 44, and Note 159, Letter 53.) 



STEREUM INSOLITUM, FROM FRANK T. McFARLAND 

 KENTUCKY (Fig. 956). Pileus ungulate, spathulate, with a short 

 stipe rooting in the ground. Sur- 

 face pale, gray, striate. Hymen- 

 ium dark, cinereous. Cystidia 

 none. Spores globose, 4-5 mic., 

 smooth, hyaline. 



We have two species, Ste- 

 reum Sower by i and Stereum Bur- 

 tianum, both rare, and both close 

 to this, though usually meso- 

 podial and also differ in the color 

 of the hymenium. The adustus Fig 956 ' 



hymenium suggests a Thelephora at first, in fact the plant in general 

 appearance is much like Thelephora multi- 

 partita. It must be very rare, for never before 

 sent to me. I would enter it in section 9 of my 

 Stipitate Stereums. 



FAVOLUS SQUAMIGER, FROM REV. 

 J. WILSON, AUSTRALIA (Figs. 957 and 958). 

 We doubt very much if 

 this is the same as Ber- 

 keley named, but it is bet- 

 ter to give an old indefinite 

 name a meaning than to 

 propose a new name. 

 Favolus squamiger is 

 known only from the old 

 type at Kew, a mesopodial

 very applicable to this plant, and as it is very close to arcularius, it
