Peziza fusicarpa Ger ., Etc.

My conclusions based upon a study of the material indicated 
may be stated briefly as follows: Peziza fusicarpa Ger. (1873), 
P. pubida B. & C. (1875), and P. morgani Mass. (1902) are 
specifically identical and synonymous; P. semitosta B. & C., 
while closely allied to P. pubida B. & C., is not identical with it, 
but is specificly distinct; P. hainesii Ell. (1881) is identical with 
P. semitosta B. & C. (1875), as recently stated by Ellis himself 
(Jour. Myc. 10: 170). 
Whether these species shall be assigned to Lachnea or Mac¬ 
ropodia of Saccardo’s arrangement may be regarded as a matter 
of individual opinion. The descriptions indicate the presence or 
absence of a stem as the primary distinction between the genera. 
This is surely a most illusive character. P. fusicarpa shows 
great variability in this respect. Often in a single cluster one 
finds a range from cups absolutely sessile to those with stems 
of maximum size. An examination of hundreds of growing 
plants shows that one-half or two-thirds, perhaps, possess some 
sort of a stem. Lachnea as defined by Saccardo and others is 
certainly a complex which must be broken up. The name even 
must be abandoned for a genus of fungi. Macropodia Fckl. was 
based on a single species M. macropus (Pers.) Fckl., which is 
included by many writers in Helvella, a refernce which seems at 
least problematical. The excipular structure of the species here 
considered is quite different from that of most of the species 
of Lachnea, but corresponds more closely to that of M. macropus. 
The general pliable, leathery texture indicates further relation¬ 
ship with that species. In Macropodia, then, our plants may 
best be placed until the time when the whole group shall have 
been thoroughly worked over and revised in accordance with 
other and perhaps better bases of arrangement. 
My ideas of the characters and specific limits of the two 
species may be gotten from the following descriptions.
