Lachnea aurantopsis (Ellis) Sacc, Syll Fung. 8: 180. 1889. 



Plate 11, f. ii. 



Peziza (Sarcoscypha) aurantiopsis Ellis, Bull. Torrey CI. 9 : 

 18. 1882. 



Plauts sessile, about 2 to 3 cm. in diameter, with a coarse, felt- 

 like, black-brown mycelium at the base, cups also clothed with 

 brown hairs; hairs septate, minutely rough toward the ends, 

 flexuose, about 10/* in diameter and of nearly uniform thickness, 

 blunt; hymenium clear, pale yellow, nearly sulphur-yellow, be- 

 coming dull orange when dry; asci cylindrical, 8-spored, 175 to 

 200/x long; spores elliptical, very large, about 15 by 28/*; para- 

 physes clavate. 



On ground, decaying wood and other materials. 



The specimens collected in Iowa by Air. Holway which were 

 referred to this species by Mr. Ellis do not conform well. The 

 spores are smaller, the hairs rigid and the septa more numerous. 

 The plants are also smaller. 



Mr. Ellis indicated by a note on this specimen that it might be 

 a form of Peziza lanuginosa Bull. The drawings in this paper 

 were made from the type material in the Ellis collection. 



Lachnea stercorea (Pers.) Gill., Discom. 76. 1879. 



Peziza stercorea Pers. Obs. Myc. 2 : 89. 1799. 



Plants gregarious or scattered, sessile, at first subglobose, then 

 concave, becoming plane, dull red, clothed externally with a 

 dense covering of brown hairs which are often branched or 

 stellate ; asci cylindrical, 8-spored ; spores elliptical, smooth, 20 to 

 22 by 8 to 9/x; paraphyses clavate. 



On cow dung. 



The species is peculiar in its habitat and the presence of stel- 

 late hairs in addition to the ordinary straight ones on the ex- 

 terior of the plants. Not common. 



Lachnea setosa (Nees) Gill. Discom., 75. 1879. 



Peziza setosa Nees, Syst. Pilze. 260. 1817. 



Plants thickly gregarious, 1 to 4 mm. in diameter, clothed with 

 very long, brown, septate hairs; hairs as long as 600/x, hyme- 

 nium plane, orange; asci cylindrical, 8-spored; spores elliptical
