1918] STEVENS—MELIOLA PARASITES 231 
Nectria meliolicola, sp. nov.—Amphigenous, spot none, myce- 
lium white, closely appressed to the Meliola mycelium and to the 
leaf, usually coextensive with the Meliola or slightly exceeding it. 
Perithecia very minute, 50-60 pw at center or near edge of colony, 
hyaline, hairy at apex, hairs 15 wu long. Asci ovate to ellipti- 
cal, obtuse, stipitate, 40-45 X11-14 uw; spores 1-seriate, oblique, 
1-septate, hyaline, linear, 24-28 X 3-4 u, acute. 
Associated with an undetermined Fusarium on Meliola paulliniae Stev. 
on Casearia sylvestris, 1051, Mayaguez (type 
It is impossible to distinguish the niveau of this fungus from that of 
the Fusarium, and it is probable that the two are one. The spot caused on the 
leaf is not due to these fungi but to the Meliola. 
Nectria portoricensis, sp. nov.—Colonies approximately circular 
on Meliola, 3-7 mm. in diameter, white, central portion bearing 
perithecia, outer part sterile. White mycelium covering each 
Meliola strand with a shaggy coat. Perithecia red, small, 160 y, 
smooth; asci 25~36 8 yw, obovate, obtuse; spores 1-seriate, oblique, 
oblong, hyaline, pale to green, 1-septate, 12 X3 m, obtuse. 
Distinguished from N. pipericola P. Henn. by absence of perithecial setae, 
shape and size of spores, and by habit of the sterile mycelium; from V. bakeri 
Rehm. by spore characters. On Meliola rectangularis Stev. on Banisteria 
laurifolia, 1001, Jayuya (type). 
is fungus differs strikingly from all other Porto Rican Nectriaceous 
fungi in the beautifully arranged, dense, shaggy, white mycelial coating which 
drapes with geometrical accuracy every affected strand of the Meliola myce- 
lium. A white mycelium of appearance similar to this was abundant, over- 
growing colonies of Meliola melastromacearum Speg. no. 7037, but no perithecia 
were seen

Sets on this host showed a pale olivaceous tint. The form on Eupa- 
torium portoricense usually forms a mat of densely felted mycelium and may 
be a distinct species. On Meliola monensis Stev. on Amyris elemifera, 6158,
