112 Mk. G. MASSEE—REDESCRIPTIONS OF 
then muriform, 20-24 x 7-9 »; paraphyses slender, apex slightly 
incrassated. 
Dothiora elegans, Sace. Syll. viii. n. 3151 (1889). 
Exsicc. Rav. Fung. Carol. n. 51 (on Pinus Taeda). 
On sheaths of living pine trees. Lower Carolina (Zavenel, 
n. 3678). 
This species belongs to the genus Tridens; differing from 
Phacidium in the muriform spores, and from Dothiora, in which 
it is placed by Saccardo, in not being erumpent. 
The species will stand as TRIDENS ELEGANS. 
Puacipium timiratum, Berk. & M. A. Curt. in Journ. Linn. 
Soc., Bot. x. (1869) p. 371. (PI. 5. figs. 14, 15.) 
Ascophores gregarious, seated on pale spots which are bounded 
by a thin black line, up to 1 mm. across, epidermis usually split- 
ting into three acute teeth; dise plane, pallid; asci narrowly 
cylindrical, apex rounded, not blue with iodine, pedicel suddenly 
narrowed, usually oblique, 100-110x8 »; spores hyaline, fili- 
form, multi-septate, nearly as long as the ascus, arranged in a 
parallel fascicle; paraphyses slender, septate. 
Coccomyces limitatus, Sace., Syll. viii. n. 8063. 
On dead leaves of Clusia parasitica. 
PHACIDIUM ELEGANTISSIMUM, Berk. §& M. A. Curt. in Grevillea, 
iv. (1875) p.5; Sace. Syll. viii. n. 2906. (PI. 5. figs. 10, 11.) 
Epiphyllous, forming scattered or confluent white patches 
2-4 mm. diameter, bounded by a dark line; ascophores seated 
on the patches, numerous, often arranged in irregular concentric 
rings, epidermis usually split into three acute teeth; dise plane, 
dingy, persistently immersed in the substance of the matrix; 
asci clavate or broadly cylindric-clavate, with a very short, 
abrupt pedicel, apex rounded, not blue with iodine, wall thick ; 
spores 8, hyaline, irregularly grouped in a mass, elliptic-oblong, 
ends obtuse, at first 3-septate, afterwards muriform, vertical 
septa 1-3, 20-23 x 8-10 1; paraphyses slender. 
On leaves of Ilea opaca, Alabama (Peters, n. 4572); on the 
same host from 8. Carolina (Ravenel). 
Some of the Alabama specimens are quite mature, and contain 
fruit, from which the above description is prepared. The fungus 
is in reality a Phacidium in appearance, but having muriform 
spores and an immersed disc, requires the creation of a new 
genus for its reception. The following is proposed :—
