Gen. XIII, Siueerostilbe, Tul. Carp. Ill, p. 103.— Perithecia 
associated with or growing at the base of the conidiophorous fungi 
( Stilbum sp.), otherwise as Nectria. 
151. Sph^erostilbe flammea, Tul. 1. c. 
Perithecia globose, bright red, nearly smooth, crowded on and near 
the conidiophorus stroma (Atractium flammeum, B. & Rav.); asci obovate- 
oblong, 8-spored; sporidia ovate, obtuse, 1-septate, hyaline, slightly 
constricted, 12—10 x 5—0 p. The conidial fungus, as represented in Rav. 
Fungi Car. V, 80, has the stromata at first narrow-conical, becoming 
finally flattened above and subpezizoid. The conidia linear-lanceolate, 
very large (SO—ICO x 64 p), a little curved, 0-9-septate, hyaline, with a 
tinge of ro.'-e color. On maple bark, Carolina (Ravenel); on Salix, Loui¬ 
siana, Langlois, No. 377. Berkeley, in Grev. IV, p. 47, adds : “ There is 
a very distinct species on Magnolia glauca , Car. Inf., No. 5005 [Atractium 
pallidum , B. & C.), with short, fusiform spores 13 p long, with the 
endochrome retracted to either end.'” 
152. Spieerostilbe coccopiiila, Tul. 1. c. 
Perithecia numerous, on and near the conidiophorous stromata, very 
small, globose, obtuse, minutely papillate, very smooth, bright red, often 
4—5 together, collapsing when old; asci linear, 60—80 x 64 !>■; sporidia 
oblique, 1-seriate. ovate, 10 x 5 p, 1-septate, subhyaline, slightly con¬ 
stricted. The conidial stage (Microcera coccopiiila, Desm., which has 
been sent from Florida by Dr. Martin and collected in Carolina by Mr. 
Ravenel (F. Am., 286), has the stroma arising from various species of 
dead bark lice. It is red, obtuse and about two millim. high. The 
conidia are linear-lanceolate, 5—7-septate and 55—65 x 5—6 p, nearly 
hyaline. 
153. Spieerostilbe gracilipes, Tul. 1. c. 
Perithecia collected at the base of the stilbum, small (one third 
millim.), red, light pruinose, fading out; asci cylindric-clavate ; sporidia 
uniseriate, ovoid. 12—16 x 44—6 p. The conidiophorous fungus (Stilbum 
corynoides , E. & E ) has the stem slender, gray, becoming nearly black, 1—4 
cm. long, head globose 4—4 millim.), orange-yellow, becoming fuscous ; 
conidia oblong-elliptical, hyaline, 5—6 x 14 P. On Hibiscus, Carya, Melia 
and Plat-anus , Carolina (Curtis and Ravenel); on Melia , Louisiana 
(Langlois). 
154. SpiiaUvOstilbe cinnabarina, Tul. 1. c. 
Perithecia growing at the base of the conidiophorous stroma (Stil¬ 
bum cinnabarinum , Mont.), few, sessile, globose, scarcely papillate, very 
smooth, orange-red, finally collapsing partially; asci clavate-oblong, 
80 x 13—16 p; sporidia biseriate, ovate-oblong, 22—26 x 7 P, plurinucleate; 
conidial stroma bacillary, clavate above, red, conidia ovoid, small, 
34 x 14 P. On trunks of Carya , Morus and Rhus, Carolina (Ravenel), 
Louisiana (Hale).
