pean authors. De Thiimen’s specimens are cited by Winter * 
and are probably authentic. The specimens distributed by 
Ellis cannot be Hyfoxylon rubiginosum (Pers.) Fr. They 
agree with the fungus upon Magnolia described by Berkeley + 
as Hypoxylon epipheum B. & C. (in some works spelled 
epiphlwune) and the species has been so cited inthe following list. 
In all, nineteen species of Xylariacez are included in the list 
given below. They are distributed among five genera as fol- 
lows: Wummularia, 3; Ustulina, 1; Hypoxylon, 12; Daldinia, 
25 A yloria, 1. 
Owing to the somewhat desultory manner in which these col- 
lections of fungi have been made, many species which doubtless 
occur in the State have not been collected as yet, while some of 
the more abundant and more noticeable species have been col- 
lected many times.
