by 2 fx (Petch). On branches, Ceylon.

Phyllachora huberi H.eim.=GUtacauma huberi (P. Henn.) Theiss. and Syd. 
Phyllosticta heveae Zimm. Affected areas show on both sides of the leaf light 
yellowish brown, without definite colored margin; pycnidia scattered, 
epipHyllous, subepidermal, erumpent. brown, edges of ostiolum black. 71 
to 15(5 ll in diameter; ostiolum 10 ll in diameter; spores elongate-elliptic 
or pointed at one end. faintly biguttulate, hyaline, average 7 by 2.2 ll. On 
living leaves of Hevea bratiliensis and 11. guyanensis, Amazon region, 
Java, Ceylon, Malay Peninsula. 
P. ramicola Petch. Pycnidia 0.1 to 0.2.1 millimeter in diameter, black, sub- 
epidermal, crowded, slightly prominent, lenticular. 7o to 140 ll high; 
spores narrow-oval, ends acute, often biguttulate, greenish hyaline, 8 to 12 
by 2 to 3 n, issuing in a line white tendril (Petch). On green stems, 
Ceylon, .lava, Malay Peninsula. 
P. sp. Spots on both sides of the leaf, round or irregular (later involving the 
margin and large areas of the leaf surface), reddish brown at first, becom- 
ing gray on the upper side of tiie leaf with reddish brown margin, con- 
Stantly reddish brown beneath; pycnidia scattered, epiphyllous, black, 
subepidermal, slightly erumpent, lenticular, ostiolate. 100 to 125 ll in 
diameter: spores ellipsoid, ends usually obtuse, often biguttulate, greenish 
hyaline, average (.10) 5.2 by 2.2 ll. On leaves. Amazon Valley. 
PhyUostietina sp. On irregular small or broadly expanding reddish brown 
areas; pycnidia gregarious or scattered, slightly erumpent, mostly sub- 
merged, subglobose or lenticular, black, papillate, ostiolate; spores globose 
or subglobose, sometimes slightly elliptic, hyaline, multiguttulate when 
young, smooth, average 7.3 by 0.1 ll: spore masses mucilaginous, adhering, 
on living leaves. The fungus is not to be confused with immature spores 
of Diplodia theobromae. The genus Phyllostictina Syd. was emended by 
V. Hohnel as follows : " Stroma imperfectly developed, in or under the 
epidermis, sometimes merely indicated by loosely intertwined dark-colored 
hyplne; pycnidia small, scattered or stromatically gregarious with indefi- 
nite ostiola : conidiophores simple, soon disappearing; conidia globose to 
broadly ellipsoid, smooth, hyaline, unicellular, delicate cell walls with 
uniform granular content. Spore form of Guignardia Yiala and Rayaz 
and possibly also related Phyllachoracese." See G. heveae Syd., Ann.
