32. Poria fimbriatella (Peck) Sacc. Syll. Fung. 6: 303. 1888 

 Polyporus fimbriatellus Peck, Ann. Rep. N. Y. State Mus. 38 : 91. 



i38 5 . 



Originally described as follows from specimens collected by 

 Dr. Peck on maple logs at Osceola, New York, in August. Also 

 collected by him on a maple trunk at Ampersand Pond. 



" Widely effused, thin, tenacious, separable from the matrix, 

 with a thin white fimbriate margin and a white subiculum, run- 

 ning into rhizomorphoid branching strings of mycelium or form- 

 ing a somewhat reticulate fimbriate membrane ; pores minute, 

 subrotund, equal, whitish inclining to cream color. 



" By its rhizomorphoid mycelium this species is related to P. 

 Vaillantii, but the pores are smaller and not collected in heaps as 

 in that species. By reason of its tenacious substance it is readily 

 separable even from an irregular matrix." 



I have recently had an opportunity to examine the types of this 

 species, which are well preserved at Albany. According to Over- 

 holts, the spores are ellipsoid, 2.5-3.5x2//,; cystidia pointed, 

 abundant, reaching 10-15^ in diameter and projecting 10-30^. 



33. Poria griseoalba (Peck) Sacc. Syll. Fung. 6: 306. 1888 

 Polyporus griseoalbus Peck, Ann. Rep. N. Y. State Mus. 38: 91. 



1885. 



Described as follows from specimens collected by Peck on soft, 

 decaying wood of deciduous trees at Osceola, New York, in July. 



" Effused, thin, tender, adnate, uneven, scarcely margined, in- 

 determinate, grayish-white, with a thin pulverulent subiculum; 

 pores very minute, subrotund, often oblique. 



" The pores are sometimes collected in little heaps of tubercles 

 as in P. molluscus and P. Vaillantii. In the dried state they are 

 slightly tinged with creamy yellow." 



The type specimens at Albany are pure-white, delicate, with 

 fairly regular hymenium, reminding me somewhat of Poria tenuis 

 Schw. and of plants referred to Poria vulgaris by many Amer- 

 ican mycologists.
