 linear striae usually of great length and often merged into a continuous stratum of dusty 

 reddish-black spore-balls ; spore-balls oblong to subspherical, 16-32 /^ in length ; sterile 

 cells often incompletely covering the spores, hyaline or yellowish-tinted, subspherical to 

 oblong usually with distended and uniformly thickened walls; spores reddish-brown,
