BERKELEY’S TYPES OF FUNGI. 111 
spores 8, irregularly 2-seriate upwards, 1-seriate below, elliptical, 
ends rather acute, 3-septate, second cell from the apex often 
slightly larger than the remainder, smooth, pale brown, 16-19 x 
7-8; paraphyses numerous, septate, rather stout, often 
branched, agglutinated together at the scarcely thickened tips 
by a brown substance. 
On bark, Virginian Mountains (Curtis, n. 3338); on apple- 
tree bark, New England (Russell, n. 5940). 
The present species is a typical Scleroderris, and must take 
the name ScLERoDERRIS GyROSA. Remarkable for the ascophores 
becoming lateraily compressed until the opposite sides meet, 
thus completely concealing the disc, and looking exactly like 
some Hysterium. In this condition the ascophore is either 
straight or more or less curved. 
Puacrpium pLurIDENS, Berk. & M. A. Curt. in Journ. Linn. 
Soc., Bot. x. (1869) p. 871. (PI. 5. fig. 16.) 
Ascophores gregarious on large discoloured spots, which are 
not bounded by a darker margin; disc circular, somewhat 
convex, blackish, eventually rupturing the epidermis into a 
variable number of acute teeth (usually 4-7), about 1 mm. 
diameter; asci cylindrical, apex rounded, not blue with iodine, 
with a short, slender, and usually oblique pedicel, about 95- 
100x9,; spores 8, filiform, nearly as long as the ascus, 
arranged in a parallel fascicle; paraphyses slender, only very 
slightly or not at all thickened at the tip. 
Coccomyces pluridens, Sace. Syll. viii. n. 3062 (1889). 
On the leaves of Clusia parasitica. Cuba (Wright, nn. 531, 
582, 533). 
The specimen in the Kew copy of Wright’s Fungi Cubenses, 
n. 713, which is called Phacidium pluridens, Berk., is something 
quite different to that species. 
Puactprum ELEGaNns, Berk. § M. A. Curt. in Grevillea, iv. 
(1875) p. 7. (PI. 5. figs. 12, 13.) a 
Seattered, black, subcircular, hypothecium thin, epithecium 
adnate to the epidermis, which splits at maturity into usually 
three acute teeth; disc dingy, not at all erumpent, 05-1 mm. 
diam. ;_asci broadly subcylindrical, almost or quite sessile, wall 
thick, not blue with iodine, 85-95 x 15-18 » ; spores 8, hyaline, 
irregularly biseriate, elliptical or subciavate, at first 5—7-septate,
