pean authors. De Thiimen's specimens are cited by Winter * 

 and are probably authentic. The specimens distributed by 

 Ellis cannot be Hypoxylon rubiginosum (Pers.) Fr. They 

 agree with the fungus upon Magnolia described by Berkeley f 

 as Hypoxylon epiphceum B. & C. (in some works spelled 

 epiphlceum} and the species has been so cited in the following list. 



In all, nineteen species of Xylariaceae are included in the list 

 given below. They are distributed among five genera as fol- 

 lows : Nummularia, 3 ; Ustulina, i ; Hypoxylon, 12 ; Daldinia, 

 2 ; Xylaria, i. 



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.
