A NEW CHAETOSPHAERIA. 
A. P. MORGAN. 
Chaetosphaeria ludens Morgan sp. nov.—Perithecia glo¬ 
bose, simply perforated, invested with long pale brown bristles, 
gregarious, seated on a very thin brown or blackish crust, scan¬ 
tily fibrillose. Asci 4-sporous, paraphysate, with a long stalk, 
130-150x8-9 mic.; spores elliptic-oblong, slightly inaequilat- 
eral, obtuse at both ends, at first hyaline and simple, becoming 
brown and 1-3-septate, 17-20x7-8 mic. 
Growing on old wood of Acer. Perithecia 0.4-0.5 mm. in 
diameter, the pellucid unseptate bristles 0.15-0.20 mm. in length. 
It is possible that two different species may be involved in Ch. 
pannicola (B. & C.) of the N. A. Pyrenomycetes; but the very 
different asci containing but four spores sharply distinguish our 
species from the one therein described.
