It is perhaps significant that the host on Aloiia Island was of 
the thornless form. Though systematists do not recognize this 
as a distinct variety or species, the fungus upon it is distinctly 
dififerent from that found on the excessively spiny Porto Rican 
form of host. 
lo. Phyllosticta divergens Sacc. Malpighia 5: 281. 1891 
On fruit of Albi:jz{a Lebbeck (L.) Benth. in Porto Rico, i8/j. 
This fungus is probably Phyllosticta divergens Sacc., which is 
reported on the leaves of this host, though there is no definite 
spot on the fruit as is described on the leaves. The conidia agree 
in length with those described but are narrower. 
11. Phyllosticta guanicensis sp. nov. 
Spots scattered, amphigenous, round, 1-2 mm. in diam., yel- 
lowish-brown with a reddish-brown slightly raised margin; pyc- 
nidia epiphyllous, few, scattered, spherical, 96-120 /x in diam., 
ostiole distinct, 12-15.8 /x in diam.; conidia hyaline, spherical to 
ovate, somewhat irregular, granular, 4.8-9.6 X 4-8 /x. 
On leaves of Giiilandina crista (L.) Small in Porto Rico: 
Guanica, 33P (type). 
12. Phyllosticta erythrinicola sp. nov. 
Spots few to numerous, scattered, small, circular, amphigenous, 
sordid-white, margin definite, regular, the brown centers falling 
out with age, portion of the leaf about the spot yellowish-brown ; 
pycnidia epiphyllous, scattered, dark-brown, spherical 36-72 /x in 
diam., ostiole very dark, indistinct ; conidia hyaline, ovate, minute, 
2.4-3.6 X 1.2 IX. 
On leaves of Erythrina micropteryx Poepp. in Porto Rico: 
Villa Alba, no (type) ; Jajome Alta, 5633; Yauco, 3157 ; Maya- 
giiez, 68. 
Very common in all parts of the island, causing serious spot- 
ting of the foliage. 
This species is distinct from Phyllosticta Erythrinae, which is 
reported on the branches of Erythrina Lithospennae. The pyc- 
nidia described are much larger, 90-180 X 60-70 fx, and lenticular 
in shape ; the conidia were described as linear-ovate, 6-8 X 2 /x.
