Hone: pezizales, phacidiales and tuberales of minn. yy 



up to 4 cm. in diameter when mature ; margin torn and repand ; 

 hymenium smooth when young, becoming pitted shghtly with age, 

 tan to brown ; exterior subpruinose or pruinose, white ; stipe white, 

 shghtly sulcate, 5-6 mm. long; spores broadly elliptical, blunt, hya- 

 line, thick-walled with yellow tinge, eguttulate, very finely granu- 

 late, smooth, numerous, 12-14x8-9 mic. ; paraphyses septate, 

 slightly constricted at septations, clavate, branched, up to 6 mic. 

 wide at apex. 



Growing on street sweepings in boxes of Narcissus in green 

 house: Hennepin, Feb. -Mar. 1908, Hone 1009. 



The asci of the Minnesota specimens stain blue with iodine while 

 the peculiar constricted character of the paraphyses which Bresa- 

 dola (35. p. 75. pi. 188.) describes and figures agrees perfectly. 

 The specimens were not found growing upon crevices in a wall 

 as usually given for P. muralis (Sow.) Rehm, but in dust and 

 street sweepings in a box. Bresadola has placed the two species 

 P. muralis Sow. and P. varia Fr. under the same species, where 

 they undoubtedly belong.

Single, stipitate, cupulate later margin turned back, whole white to 

 dirty tan, brittle, up to 2-3 cm. in diameter; margin very thin and 

 crenate, disappearing ; hymenium smooth ; stipe short, 4 mm. long, 

 2 mm. thick ; exterior pruinose ; spores broadly elliptical, blunt, hya- 

 line, thick-walled, smooth, eguttulate, 12-14x6-8 mic, very numer- 

 ous ; paraphyses fihform very slightly enlarged at apex. 



Growing on street sweepings in boxes of Narcissus in company 

 with Plicaria muralis (Sow.) Rehm in green house. Hennepin, 

 Mar. 1908, Hone 1008. 



Difl:'ers from Plicaria muralis (Sow.) Rehm in structure of ex- 

 cipulum and hypothecium being much thinner, also truly cupulate, 

 not turning back; hymenium and exterior are of same color, and 

 paraphyses are filiform.
