VIIL.MMYCOSPHAERELLA PALMAE Sp. Mov. 
Spots amphigenous, from small and oval to quite long and 
narrow, with the long axis parallel to that of the leaf, light- 
brown, surrounded by a narrow, dark-brown line. Perithecia 
amphigenous, small, dark, immersed often closely aggregated, 
80-90 microns in diameter, ostiolate. No paraphyses. Asci 
oblong or broadly clavate, straight, 45-50x17 microns. Spores 
hyaline, uniseptate, not constricted, fusoid, straight or curved, 
usually curved, pointed at both ends, 30-35x4-5 microns, 
On leaves of palms in Porto Rico; Guanica, 2107 (type). 
VIIIL.—MYCOSPHAERELLA CHRYSOBALANI Sp. nov. 
Spots amphigenous, irregular, both in size and outline, usu- 
ally becoming confluent so as to cover a large part of the 
upper leaf surface; on upper side covered by a white, cinereous 
membrane, which makes the spots very conspicuous. Peri- 
thecia epiphyllous, numerous, black, erumpent, scattered, 100 
microns in diameter, ostiolate. No paraphyses. Asci ovate 
cr oblong, 40-50x15 microns. Spores inordinate, hyaline, uni- 
septate in the middle, not constricted, fusoid, somewhat point- 
ed at ends, straight or curved, 24x3.5 microns. 
On leaves of Chysobalanus icaco, in Porto Rico; Rio Piedras, 
5699 (type). 
IX.—MYCOSPHAERELLA ANTHURII sp. nov. 
Spots very large, sometimes 10 centimeters in diameter, 
amphigenous, somewhat irregular in outline, dry and becoming 
practically transparent, thickly studded with black perithecia, 
bounded by a narrow, dark-brown line, portions falling out and 
leaving merely a network of veins. Perithecia epiphyllous, sub- 
epidermal, very numerous, scattered over the entire spot, dark, 
ostiolate, 100-150 microns in diameter. Asci ovate, oblong, or 
broadly clavate, 45x15-18 microns. Spores ovoid or oval, 
light-green, septum usually indistinct, guttulate, inordinate, 
15-20x6 microns.
