10. ALEUKIA FUCKEL. 



Cups gregarious or solitary, fleshy, small or large, sessile or sub- 

 sessile, concave to cupulate, regular or irregular, some shade of 

 red ; exterior lighter colored, rough ; spores elliptical, strongly retic- 

 ulate at maturity, hyaline, continuous. 



1. Aleuria wisconsinensis Rehm, Ann. Mycol. 2:34. i904' 

 Gregarious or single, fleshy, saucer-shaped to plate-like ; margin 



erect, entire, smooth almost regular; hymenium smooth, red, up to 

 I cm. in diameter ; exterior glabrous, white, inconspicuous ; spores 

 elliptical, obtuse or slightly acute, reticulate often with an irregu- 

 lar apical papilla, hyaline, uniseriate, eguttulate, 14-16x8-9 mic. ; 

 paraphyses septate, filiform with globose apex, up to 6 mic. wide 

 at the apex, filled with red granules. 



On clay earth lodged in the crevices of an up-turned stump ; 

 Hennepin, Oct. 1908, Hone 2004. 



The Minnesota specimens differ from Aleuria hicucuUata Boud. 

 its nearest ally, only in being of a more red color and the spores 

 being reticulate instead of verrucose. The spores agree with those 

 of P. aurantia Mull, from which it is separated by its smaller size, 

 different habitat, and distinctly globose paraphyses. 



2. Aleuria rutilans (Fries) Gill. Discom. Franc. 53. 1879. 

 Peziza rutilans Fr. Syst. ]Myc. 2: 68. 1823. 



Humaria rutilans Sacc. Syll. Fung. 8: 133. 1889. 



Gregarious or sessile, or stipitate, subglobose becoming ex- 

 panded and plane, fleshy, from i cm.-5 mm. in diameter; margin 

 entire, raised or drooping ; hymenium orange to scarlet colored ; 

 exterior paler in color, minutely downy but never truly-villose, 

 hairs short, simple, white ; spores elliptical, slightly acute, contin- 

 uous, hyaline, uniseriate, generally one large central oil globule, 

 sometimes two, becoming minutely reticulate, but never warted, 18- 

 22x9-11 mic; paraphyses septate, slender, apex gradually clavate, 

 containing orange granules.
