Steccherinum Peckii sp. nov. 



Hymenophore pileate narrowing into a lateral stipe ; pileus 

 flabelliform, horizontal, confluent laterally, 0.5-1 cm. wide, by 

 confluence often 3 cm. wide, 0.5-1.5 cm. long, thin, less than i 

 mm. thick; surface glabrous or slightly puberulent, radiately 

 rugose, subsulcate-zonate, light-buff, concentrically zonate with 

 fine dark lines ; margin thin, subrepand ; substance fibrous, dry, 

 brittle ; stipe lateral, more or less compressed vertically, attenuate 

 to base, usually distinct, occasionally confluent, concolorous with 

 pileus, 1-8 mm. long by i— 5 mm. wide ; hymenium ochraceous, 

 more or less sharply delimited toward the stipe ; teeth crowded, 

 short, often decurrent as papillae on the stipe, ochraceous to buff, 

 terete to compressed, sometimes forked, whitish-puberulent with 

 free clavate hyphal ends, 1-2 mm. long, 9-12 to a sq. mm.; 

 spores elliptical or oblong, smooth, hyaline, granular, 2-2.5 X 

 3-3.5 fji ; hyphae hyaline, firm-walled, elastic, compactly woven, 

 infrequently septate ; tasteless ; odorless. 



On dead maple limbs in autumn at Griffin's Corners, Delaware 

 County, N. Y. Collected by C. H. Peck. 



Type in the writer's hei^barium and in the New York State 

 herbarium at Albany, N. Y. 



This elegant species is closely related to Steccherinum Rhois 

 (Schw.), from which it is clearly distinguished by the nearly 

 or quite glabrous surface of the pileus and by the sharply defined, 

 concentric, dark lines. The surface has a somewhat silky lustre 

 and this with the color markings and the graceful, clearly defined 

 form of the pileus renders the species especially attractive. I 

 take pleasure in dedicating this handsome species to the collector, 

 our mycological Nestor, Dr. C. H. Peck, State Botanist of New 

 York. 



Steccherinum basi-badium sp. nov. 



Hymenophore pileate, sessile to substipitate, somewhat con- 

 fluent; pileus dimidiate to orbicular, horizontal or ascending, 

 0.5-1.5 cm. wide, 0.5-1 cm. long, 0.2-0.3 mm. thick; surface 

 sulcate-zonate, radiately subrugose, glabrous, light-buff at margin, 

 becoming abruptly darker, umbrinous to badious toward base; 

 margin very thin, acute, substerile, incurved ; substance fibrous, 

 dry, scarcely brittle, buff to ochraceous below, badious above ; teeth 

 crowded, delicate, slender, subterete to compressed, tips minutely 

 forked or fimbriate, 0.3-0.5 mm. long X o.i mm. wide, pale-buff to 

 ochraceous, puberulent with free clavate hyphal ends; spores not
