Coprophilous Fungi . 
sequence of development is as follows : first, P hy corny cetes^ 
usually heralded in by P ilair a and Pilobolus , followed by 
species of Mucor> accompanied by their parasites Chaetocla- 
dium , Thamnidium , Piptocephalis , Syncepkalis, & c. ; next 
appear various members of the Hyphomycetes , probably in 
many instances representing the conidial condition of the 
ascigerous Fungi which are usually the last in the sequence 
to appear. 
We have found that dung can be kept under observation 
for several months if placed in a shallow vessel on a layer 
of blotting-paper kept constantly moist, and covered with 
a bell-jar ; a small quantity of naphthaline serves to check 
the ravages of various, mites, eelworms. &c. 
Systematic. 
We give below an account of the species which appeared 
on dung under observation during the six months Oct.- 
March. Only those Fungi belonging to the Ascomycetes are 
enumerated here, the Phycomycetes and Hyphomycetes being 
reserved for a future paper. Summarizing the results from 
a systematic standpoint, we may note the occurrence of two 
new genera, Pleuroascus (P. Nicholsoni\ belonging to the 
Perisporiaceae , and Spumatoria [S. longicollis) to the Sphae - 
riaceae. New species of the following genera have appeared : 
Endomyces coprophilus , Eurotium micro sporum , Magnusia 
Bartlettii , Sordaria globosa , Sporormia longipes , Microascus 
variabilis , M. nidicola , and Melanospora discospora. The 
following species are new to the British Flora i Myxotrichum 
uncinatum , Thelebolus stercoreus , Ryparobius ascophanoides , 
Eurotium insigne , Sordaria anserind , N. minima , S', hirta, 
S. setosa , N. curvicolla , S', pleiospora , N. macrospora , N. 
neglecta , 6”. W interim S. fimiseda var. appendiculata , Delitschia 
moravica , insignis, Sporormia ovina> S. pulchella , N. jime- 
taria , Sphaeroderma fimbriatum and N. Hulsebosckii . The 
genus Bovilla Sacc., founded on the single (British) species 
2?. Caproni , proves to be nothing more than the immature 
condition of Sordaria coprophila.
