BURT THELEPHORACEAE OP NORTH AMERICA. V 763 



10. S. podlachica Bresadola, Ann. Myc. 1 : 117. 1903. 

 Type : in Bresadola Herb, and a portion in Burt Herb. 

 Fructification effused, closely adnate, described as ''e 



pallido-caerulea caesio-hyalina," drying tawny olive to Sac- 

 cardo's umber where directly on the wood; structure in sec- 

 tion 30-45 /i thick, with hyphae 2 /x in diameter closely crowded 

 together and rising obliquely from substratum to the surface ; 

 basidia in upper 15 /x of fructification among the hyphal fila- 

 ments, longitudinally septate, pyrif orm, 7-10 X 6-8 /x ; spores 

 colorless, simple, even, curved, 6-7 X 3-5 jx. 



Covering areas 5 cm. long, 2 cm. broad. 



On decaying coniferous wood, Massachusetts ; on decaying 

 beech wood, Russian Poland. 



The Massachusetts collection was noted as blue-purple 

 when fresh ; in some places algae coating the wood have been 

 covered by the fructification and the modified color of this 

 algal layer is seen through the dried fructification ; where the 

 fungus coats the wood directly, the color of specimens which 

 have been several years in the herbarium is the tawny olive. 

 The American collection agrees closely with that communi- 

 cated by Bresadola. 



Specimens examined: 

 Eussian Poland : on beech wood, Eichler, comm. by Bresadola, 



part of type. 

 Massachusetts : on coniferous wood, W. G. Farlow.

 ly adnate, drying cinnamon-brown, the margin 

 determinate, thick, entire ; structure in section 

 100-140 II thick, with (1) a layer 10-30 /x thick 

 next to the substratum of longitudinally ar- 

 ranged, densely interwoven hyphae 2-2^ /x in
