CULTURAL CHARACTERS.—Cultures one month old on white corn meal have a 
uniform cadmium orange to xanthine orange color. The entire surface is covered 
with a compact growth, irregularly ridged. Tiny mars orange spore masses are 
scattered irregularly over the surface. Cultures of this species closely resemble 
E. fluens mississippiensis on this medium, being distinguished by the smaller and 
much less numerous spore masses. The medium is changed to amber brown 
just below the mycelium, shading into mars yellow; whereas, in the case of 
Li. fluens mississippiensis the color of the medium is very little changed. 
TYPE LocaLity.—‘ Calcareous hills east of Santurce, Porto Rico, altitude 
10 ft.” 
GEOGRAPHICAL DISTRIBUTION.—Porto Rico and French Guiana. 
Exsiccati.—Pycnidia and perithecia: Heller, Plants of Porto Rico, no. 4340. 
This species, which appears to be subtropical or tropical in its 
range, is known at present from only three collections, the type col- 
lection from Porto Rico, a collection by Prof. N. Wille, No. 816, 
Porto Rico, distributed by the New York Botanical Garden, from 
which the cultures were obtained ; and one made by Leprieur, No. 392, 
in French Guiana, and determined by Montagne as Diatrype radicalis 
(Schw.). A specimen of this collection apparently labeled by Mon- 
tagne and preserved in the Delessert Herbarium at Geneva has been 
examined and found to agree with the type material of F. longiros- 
tris. It is readily distinguished from £. tropicalis by its smaller asco- 
spores and pycnospores, and from £. fluens by its narrower and 
more acute ascospores and the long, slender necks of the perithecia.

TYPE SPECIMEN.—No. 2807 S. and S., on Elaeocarpus glandulifer, Hakgala, 
Ceylon, Coll. T. Petch, August, 1913. 
Pycnipia.—Stromata corticular, pustular to pulvinate, usually gregarious or 
scattered, rarely confluent, 1 to 5 mm. in diameter, early becoming friable, 
orange chrome when fresh to sanford brown when old and weathered ; pycnidia 
consisting of numerous irregular cavities in the stroma; sporophores mostly 
simple, clavate, tapering above, 6 to 10 u long. ; pycnospores continuous, oblong 
to cylindric, very variable in size and shape, pale yellowish in mass, 3.5 to 
7 by 1.5 to 2.5 ; 
PrRITHECIA.—Stromata the same or similar to those bearing pycnidia; peri- 
thecia black, membranous, collapsing when dry, 5 to 50 or more in a stroma; 
250 to 500 « diameter, irregularly arranged in one to three layers, bearing 
slender necks which penetrate the stroma and project 0.25 to 1 mm., termi- 
nating in acute ostioles; asci oblong or subclavate, nearly sessile, 40 to 50 by 
7 #3 ascospores irregularly biseriate, subelliptical, obtuse, not constricted at
