 Polyporus semitinctus Peck, Ann. Rep. N. Y. State Mus. 31 : 37. 



1879. 



Described as follows from specimens collected by Peck on the 

 under surface of maple chips at Griffins, Catskill Mountains, 

 New York, in September. 



" Subiculum thin, soft, cottony, separable from the matrix, 

 whitish, more or less tinged with lilac, sometimes forming branch- 

 ing creeping threads ; pores very short, unequal, whitish or pale 

 cream-color, the dissepiments at first obtuse, then thinner, toothed 

 on the edge. 



"This is a soft, delicate species, with merulioid pores, similar 

 to those of P. violaceus. The lilac stains appear on the subiculum 

 only." 



Three collections of this species in addition to the type are at 

 Albany, collected by Peck at Ballston, South Bethlehem, and 

 Lyndonville. According to Overholts, the spores measure 



3-4 X2/1. 



In the herbarium here, there is an excellent specimen from the 

 " Catskill Mts." sent by Peck to Ellis, which is attached to chips 

 and leaves and shows shallow tubes and a wide margin with rhizo- 

 morphic strands. During a recent visit to Albany, I compared 

 this with Peck's type and found the two identical. 



Another specimen, collected by Fairman at Lyndonville, New 

 York, in 1890, was sent to Ellis for determination, but was never 

 named. It corresponds in form to those at Albany from Ballston 

 and South Bethlehem. The largest collection we have was made 

 by Ellis at Newfield in October, 1879, on dead stems of Kalmia 

 latifolia still standing. This bears the name "Pol. aneirina Fr., ; ' 

 doubtless assigned it by Cooke, and is described by Ellis as " Milk- 

 white with a narrow, radiate-fibrose, snow-white margin. Pores 

 oblique, medium size, margins thin, suberose." 



30. Poria myceliosa Peck, Bull. N. Y. State Mus. 54: 952. 1902 



" Subiculum membranaceous separable from the matrix, con- 

 nected with white branching strands of mycelium which per- 

 meate the soft decayed wood, or with radiating ribs which run 

 through the broad sterile fimbriate white margin ; pores very
