With plentiful showers in the springtime the Morels grow 
abundantly in my vicinity. I have observed them critically for 
many years and have taken much pains to recognize as many as 
possible of the species that have been described. I invariably 
arrive at the same conclusion: that there are but two species. 
In the same spots the species vary much in form, size and color 
from year to year in accordance with the difference in warmth, 
sunshine and shower. The spores vary somewhat in different 
specimens but there is nothing characteristic in their variation.. 
No paraphyses are present in the hymenium of either species; 
I do not recognize immature or undeveloped asci as paraphyses. 
My bundles of specimens gathered in different years bear 
a variety of labels as I look them over, but they are all assembled 
in my mind under two names: The first is Morchella escu¬ 
lenta, the second Morchella patula; in the first the pileus is 
wholly adnate to the apex of the stipe; in the second the lower 
part of the pileus is separate from the stipe. The difference in 
the plants under each species do not seem to me sufficient to 
establish good varieties even. 
Judging by the plants growing in this region I venture t© 
present the synonomy of the two species as follows: 
I. MORCHELLA ESCULENTA. 
1. Boletus esculentus rugosus, etc., 3.
