S. chlorascens Burt 



Plate 27, fig. 15 



Typ 



Mo. Bot. Gard. Herb, and in Farlow Herb 



Fructification coriaceous, drying cream-color with glaucous 

 tint, effused, ascending and incrusting the mossy bases of 



trees and forming imbricated, free, pileate, 

 sterile branches, the apices spiculose or fim- 

 briate ; hymenium gelatinous, drying vinaceous 

 brown, occurring in somewhat scattered spots 

 on the lower portions of the fructification; 

 structure in section 800 n thick, with (1) a 

 broad, spongy layer next to the substratum of 



loosely interwoven, rather 



gid 



walled

Parapliyses,

hyphae 2£-3 n in diameter, which bear (2) a 

 sharply differentiated hymenial layer 140-240 /x 

 thick, composed of rod-like parapliyses 2 /x in 

 diameter, between which occur basidia through- 

 out the outer 60 p of the layer; basidia longi- 

 tudinally septate, pyriform, 15-18x12 m; spores 

 simple, colorless, flattened on one side, 10-10 J X 



6-7 /x. 

 Ascending objects 2-4 cm., 1-2 cm. broad; 



Florida. Autumn 



free branches up to 5 mm. long. 



On mossy bases of living trees. 



As shown by the figures in pi. 27, the pileate branches of 

 S. chlorascens do not resemble those of S 



The 



structure in section is different in every detail from that of 

 specimens of the latter species and approaches more closely 

 that of S. Helvelloides, but the fructification is thinner than 

 that of the latter, has smaller basidia and spores, and the 

 basidia distributed from the surface to about 60 n below the 

 surface, and forms free pileate branches.
