Peziza incrustata Ellis, Am. Nat. 17: 192. 1883. 



Mollisia trametis Ellis & Ev. Proc. Acad. Sci. Phila. 1893: 147. 1893. 



Psendohelotium incnistatum Sacc. Syll. Fung. 8: 301. 1889. 



Apothecia growing on the margin and inner surface of the 

 pores of the host, obconic, .11-. 15 mm. in diameter, honey- 

 colored, of fibrous structure, the ends of the fibers projecting so 

 that the outer surface and margin appear granulose-pubescent, 

 or as if covered with sharp-pointed granules, at first convex- 

 hemispheric, resembling a Nectria, soon becoming concave with a 

 distinct subfimbriate margin; asci clavate, reaching a length of 

 20-23 fji and a diameter of 4-5 /x; spores 2-seriate, or obliquely 

 1-seriate, narrow-ellipsoid, or clavate, 1.5-2 X 3.5-4.5 n; pa- 

 raph\'ses not observed. 



Parasitic on Poly poms Stevensii and on a resnpmsite Polyporus. 



Type locality: Newfield, New Jersey. 



Distribution: Known only from the type locality. 



The color of this species would suggest a TIelotium or Orbilia 

 rather than a Mollisia. Should be more carefully studied.

 clavate, reaching a length of 25-35 n and a diameter of 3-4 yu, 

 8-spored; spores 2-seriate, hyaline, simple, narrow-cylindric, 

 straight, or slightly curved, 1 X 5-7 ix; paraphyses filiform,
