chymatous, rough with rather numerous short, coarse hairs, es- 
pecially around the base, 180 » high, 150 # thick. 
Asci numerous, cylindric, 60-55x7-8 *, obtuse, thin walled, 
%-spored. Paraphyses numerous, thread-like, 1-1% uz, longer 
than the asci; spores linear, smoky, guttulate, obtuse, 55-65x 
2-3 m, usually crooked, septa not seen.

In the Saccardian classification, this fungus would fall in the 
Hypocreaceae-scolecosporae-phaeoscoleciae, in which there is 
only the genus Konradia from which it is clearly distinct, In 
the classification of Lindau it falls in the Hypomyceteae and 
near the genera Globulina and Torrubiella from both of which 
it presents marked differences. 
Dexierta gen nov. 
In honor of Dr. E. G. Dexter, whose liberal views so benefit- 
ed Porto Rico. 
Mycelium superficial or mainly so. Perithecium astomate, 
the wall reduced to extreme tenuity or becoming gelatinized 
and amorphous, thus leaving the asci naked or nearly so, at 
maturity. Type Dexieria pulchella. 
The genus is somewhat like Colonectria but is distinguished 
from it by the gelatinization of the perithecial wall and by 
general habit. 
Dexieria pulchella, sp. nov. Fig. 4. 
Mycelium thypophyllous, reddish, superficial, scant; spot 
none. Perithecia containing from 18-25 asci. Asci when 
mature, naked or covered only by a mucilaginous residue oi 
the perithecial wall. Surrounded at base by a few loosely 
intertwined strands of reddish-brown mycelium about 3 a» in 
thickness. Dimension of ascus exclusive of subtending my- 
celium 65-100 ». Asci clavate to ovate to elliptical, 50x15-22 
p, 8-spored, obtuse, thin-walled. Paraphyses none. Spores 
linear, 35-42x4-5 uw, hyaline, 5-septate. Pycnidia similar in 
structure but larger, 110-130 a, slightly darker in color, Co- 
nidia similar to ascospores but smaller, 17-21x3 a, and 3, not 
5-septate.
