Mycologia 



One of the most attractive of the discomycetes on account of its 

 brilliant color. Observed from material collected by one of the 

 students of the Agricultural College. 



Sarcoscypha occidentalis (Schw.) Cooke. Habitat similar 

 to that of the preceding but plants occur all summer. Stem 

 usually longer and more slender, cups smaller and shallow, saucer- 

 shaped instead of deep funnel-shaped as in the preceding. Col- 

 lected commonly in woods about Fargo. 



5. Urnula 



Urnula craterium (Schw.) Fries. Occurring in woods on 

 buried sticks, a number of specimens often attached to a single 

 stick. Plants at first club-shaped and entirely closed, finally 

 opening with a star-like aperture and becoming urn-shaped but 

 margin usually notched. Outside and inside dark brownish- 

 black. The position of this species is uncertain but on account of 

 the manner in which the cups open the genus is often included 

 with the Phacidiineae. 



6. Galactinia 



Galactinia succosa (Berk.) Cooke. Plants cup-shaped, rather 

 large, 2-3 cm. in diameter, inside brown, externally whitish. 

 When the flesh is broken the exuding juice turns golden-yellow. 

 Occurring on damp soil in shaded woods. Collected near Fargo. 



7. Peziza 



Peziza vesiculosa Bull. Large cup-shaped plants often 6-8 

 cm. in diameter, yellowish inside, whitish externally, occurring 

 usually in dense clusters on strawy manure piles and soil ferti- 

 lized with such material. The cups are at first regular in form, 

 becoming much contorted and twisted. A common species. Col- 

 lected at Sykeston. 



Peziza repanda Wallr. This species occurs on decaying logs 

 in woods, and, while it resembles the preceding in color, it differs 

 in form, the cups soon becoming repand, leaving the hymenium 

 convex. This is a species concerning which there is much doubt.
