Murrill : Light-colored Resupinate Polypores 177 



cept when varied by obliquity, thin-walled, entire, I mm. long, 4 

 to a mm.; spores ellipsoid, smooth, hyaline, 5 X 3-5^ 5 110 cystidia 

 observed. 



Type collected on much-decayed fallen branches and moss- 

 covered roots at Rio Piedras, Porto Rico, November 19, 1911, 

 /. R. Johnston 07. 



88. Poria jalapensis sp. nov. 



Effused for many centimeters, continuous, inseparable, 1-2 

 mm. thick ; margin slight, tomentose, white, inconspicuous in age ; 

 context white, conspicuous and punky in places ; hymenium mostly 

 uneven, nodulose or following the inequalities of the substratum, 

 not glistening, distinctly ochraceous in dried specimens ; tubes 

 angular, very regular, firm, rather thin-walled, 1 mm. long, 4 to a 

 mm., the edges produced into short, sharp teeth ; spores ellipsoid, 

 smooth, hyaline, 5 X 3/^; no cystidia observed. 



Type collected on a decayed hardwood trunk in a moist virgin 

 forest at Jalapa, Mexico, December 12-20, 1909, W. A. & Edna

89. Daedalea sulphurella Peck, Ann. Rep. N. Y. State Mus. 



44: 133- 1 891 



Described as follows from specimens collected by Peck on 

 much-decayed wood at Salamanca, New York, in September : 



"Resupinate, effused or nodulose, pale sulphur yellow; pores 

 short, labyrinthiform, the dissepiments often lacerated and irpici- 

 f orm in the dry plant ; spores subglobose or broadly elliptical, 

 .0002 in. long. 



" Mostly very irregular or nodulose, following the irregularities 

 of the wood and encrusting mosses. It is of a beautiful pale yel- 

 low color when fresh, but it changes to a dull pallid hue when 

 dry." 



The type at Albany is very poor, consisting mainly of a few 

 coarse teeth that suggest litle. Overholts finds the spores to be 

 ellipsoid or globose, hyaline, 5-6 X 4-j5 andf says that the 

 mature fragments seem more like an Irpcx than a Daedalea. 

 Fresh specimens would be highly desirable.
