BERKELEY'S TYPES OF FUNGI. 101 
blue with iodine, 60-707 3; spores irregularly 2-seriate, 
hyaline, smooth, very narrowly clavate, 9-12 x 2-3 jv; para- 
physes very slender, tips scarcely thickened ; hypothecium and 
excipulum consisting of densely interwoven hyphe, running out 
into a parenchymatous cortex of brown polygonal cells 9-12 » 
diam. 
Pyrenopeziza fracta, Sace. Syll. viii. n. 1467. 
On dead stems of Hydrangea vulgaris. Virginia (Ravenel, 
n. 3332). 
This species is a typical Pseudopeziza, and will stand as 
P. FRACTA. 
It is just possible that the spores may become septate at 
maturity: there are apparent indications of a mediap septum, 
but fresh material is necessary to determine the point with 
certainty. 
Prziza (Hymenoscypna) vrripi-aTra, Berk. § WM. A. Curt. in 
Journ. Linn. Soc., Bot. x. (1869) p. 369. (PI. 4. figs. 33, 34.) 
Soon expanded, discoid, often more or less wavy ; substance 
thin, sessile; dise blackish-green with a tinge of purple, outside 
similarly coloured and minutely scabrid, up to 8 mm. diameter ; 
excipulum composed entirely of very thin, densely-interlaced 
hyphe ; asci narrowly cylindrical, apex rounded, base slender 
and often bent, about 60 x 7; spores 8, 1-seriate, narrowly 
elliptic-oblong, continuous, smooth, often 2-guttulate, slightly 
tinted with brown, 5-6 x 2-25; paraphyses numerous, 
rather stout, cylindrical, septate, agglutinated together at the 
swollen, coloured tips. 
Pezicula viridi-atra, Sace. Syll. viii. n. 1308. 
On rotten wood. Cuba (Wright, n. 369). . 
When dry the substance is rigid; the colour blackish purple, 
Which instantly dissolves when treated with dilute potassium 
hydrate, giving a purple solution. The present species 18 4 
typical Chlorosplenium and hence must stand as C. VIRIDI-ATRUM 
(Berk. & M.A. Curt.). Probably Berkeley noticed this affinity 
when he remarked “ not staining the wood.” 
Prziza (Hymenoscypua) LEvcopsIs, Berk. G WM. A. Curt. in 
Journ. Linn. Soc., Bot. x. (1869) p. 368. (Pl. 4. figs. 3, 4.) 
Scattered or gregarious, stipitate, closed at first, then expand- 
ing until plane and the margin often wavy and drooping,
