PHOTOGRAPHS AND DESCRIPTIONS OF 
CUP-FUNGI— I. PEZIZA 
Fred J. Seaver 
(With Plates 155 and 156, Containing 4 Figures) 
Although the type of the genus Pesiza is in doubt, the name 
stands in current usage as it doubtless should continue to do, for 
the large fleshy cup-fungi. Notwithstanding the number of seg- 
regates which have been made on one character or another, the 
genus is still represented by a fairly large number of species. 
Many of the species of the genus cannot be satisfactorily 
studied from dried specimens alone, since the more conspicuous 
characters, such as color, form, etc., are entirely lost in this con- 
dition. In a number of species, the spores furnish valuable 
diagnostic characters, but in other cases we must rely entirely on 
gross character. For this reason, the species of the genus should 
be accompanied by complete field notes, or as is still better, by 
colored sketches or photographs or both. 
The reproduction of the plants of this group by photographs 
while inferior in many ways to reproduction by color, is less ex- 
pensive and shows many fine details which are lost even in the 
best colored illustrations. For these reasons, it is the intention 
to bring out from time to time illustrations of the common species 
of Peziza and other cup-fungi in such a way as to aid in deter- 
mining the identity of these plants as they are collected in the 
field. The following illustrations represent four of the common 
species of Peziza, the photographs having been made from local 
specimens collected by the writer in the vicinity of New York 
City.
