REPORT OF THE STATE BOTANIST I9II 35 



Bark of dead branches of poplar. Fall creek above the dam. 

 Near Ithaca. March 1894. G. F. Atkinson. 



This species differs from Teichospora disseminata 

 B. & C. in its much larger perithecia. 



Thyridium pallidum E. & E. 

 Dead branches of staghorn sumac, Rhus t y p h i n a L. 

 Vaughns. June. S. H. Burnham. 



Tricholoma boreale Fr. 

 Lawns near Dudley observatory grounds under or near Austrian 

 pine trees. Albany. November. S. H. Burnham. 



Tricholoma planiceps n. sp. 



Pileus fleshy but very thin, broadly convex or plane, glabrous, 

 grayish brown or yellowish brown with the thin acute margin some- 

 times whitened by a very thin flocculent tomentum, flesh white; 

 lamellae thin, narrow, close, slightly sinuate, white or whitish ; stem 

 slender, straight, stuffed or hollow, colored like but a little paler 

 than the pileus; spores broadly ellipsoid, 7-8x5-6 ft. 



Pileus 2-5 cm broad ; stem 4-6 cm long, 4-6 mm thick. 



In arbor vitae groves. North River. September. 



Allied to Tricholoma melaleucum ( Pers.) Fr. from 

 which it differs in its very regular plane orbicular pileus, its more 

 crowded narrow lamellae, its strict stem and broader spores. Its 

 habitat is peculiar having been found only under white cedar trees, 

 Thuja occiden talis L., and in but one locality. In this 

 station it has been found two years in succession. 



Tricholoma subsaponaceum n. sp. 

 Pileus fleshy, compact, flexible, convex or nearly plane, glabrous, 

 whitish creamy white or pallid on the margin, smoky brown or 

 alutaceous in the center, sometimes marked by a row of pallid or 

 watery spots near the margin, assuming yellow or saffron hues 

 where cut or bruised, flesh white, changing color like the pileus 

 where cut or wounded, odor pleasant like anise, taste farinaceous ; 

 lamellae broad, close, adnexed or nearly free, whitish ; stem variable, 

 equal or enlarged at the top or at the base, sometimes compressed, 

 often abruptly narrowed at the base and radicating, silky fibrillose, 

 solid becoming hollow with age, whitish, changing color like the 

 pileus where cut or bruised ; spores broadly ellipsoid or subglobose, 

 5-6 x 4-5 ft.
