Harper—Additional Species of Pholiota. 399 
by its smaller spores. These are more brown than the spores of 
Pholiota praecox Pers. and make it doubtful whether the species 
would not better be placed in the genus Stropharia.” 
SYNOPSIS OF THE FORMS ILLUSTRATED 
1. Typical Pholiota dura.Pis. XI-XIIIAB 
2. Plants with thinner, more expanded and less cracked 
pileus and smaller spores. Similar to Pholiota 
duroides Pk.Yol. XVII, PI. XXIX. 
3. Plants with long nearly equal stems and appendicu- 
late veil.PL XIIICD. 
4. Typical Pholiota praecox.PI. XIVCD. 
5. Plants with appendiculate veil. Similar to Pholiota 
praecox, var minor. Also a form with the pileus 
umbonate.....VoL XVII, PI. XXVII. 
6. Plants with stems enlarged below and distant annu¬ 
lus. Similar to Pholiota sphaleromorpha Bull, and 
Pholiota howeana Pk. 
.PI. XIVAB and Vol. XVII, pi. XXVI. 
7. Autumn plants like Pholiota praecox but with the 
pileus cracking. Pholiota vermiflua Pk. 
Vol. XVII, pi. XXVIII, C—F. 
8. Plants with the lamellae obliquely truncate next the 
stem. Pholiota temnophylla Pk. 
Vol. XVII, pi. XXXIIIA. 
Other forms reported from the United States are mentioned 
in Vol. XVII, pp. 477-481. Further study emphasizes the 
remark on page 481 regarding the variability of plants in this 
group. 
Whether the variation in the group is the same in Europe 
as in the United States or not we have not the data to decide 
fully. The two species Pholiota praecox and Pholiota dura 
are reported in most European floras. Var. minor is reported 
from the British Isles and Bavaria. Pholiota sphalero¬ 
morpha is reported from France, Germany and Bavaria. 
Pholiota gibberosa Fr. is a small fragile form with free 
gills reported from Germany but so far as I am aware has 
not been found in this country.
