originates under the cuticle which is soon thrown oil*. The gen¬ 
eral appearance is that of II. punctulatum B. & Rav. and it has 
the same hard brittle stroma as that species. 
Hypoxylon effusum, Nitschke, Pyr. Germ.p. 48.—On decaying 
wood of CJlinus Americana, Concordia, Mo., Dec. 1888, Rev. C. 
H. Demetrio, 56(b). (Also Kansas, Kellerman & Louisiana Langlois, 
No. 299). Stroma superficial, thin, forming black crust like 
patches of various size and shape, 3—4 mm. across or often con- 
fluently seriate 3 —4 cm. or more by J—1 cm. wide. Perithecia 
in a single layer, rather large (the central cavity being about J 
nun. diam.), prominent but mostly flattened above with a central 
papilla much as in H. annulatum Schw. but not so distinctly 
annulate depressed. The specimens were old and the asci dis¬ 
solved but the sporidia were still tolerably abundant, ovate-oblong 
and subnavicular, pale-brown 6—8 x 3—3J, rounded and obtuse 
at the ends. The perithecia and sporidia were rather larger than 
in Saccardo’s specimen in M. V. 1470 and the stroma thinner but 
there can hardly be any doubt that our specimens are correctly 
determined. Nitschke’s specimens were gathered in the spring 
and were then in good condition. The Mo, specc. gathered in the 
fall would naturally be past their prime assuming that the species 
matures in the spring of the year. 
Hypoxylon concurrent, B. & C. Grey. IV, p. 93. - Carolina 
(Ravenel, without habitat), on Acer macrophyllum, Gala. (Hark- 
ness.) “Perithecia connate forming a thin black uniform stratum, 
very minutely granulated, the upper part only exposed; ostiola 
minute, papillseform: sporidia shortly cymbaeform, uninucleate.” 
(10 x 5 micr. Cke.) 
Hypoxylon Beaumontii, B. & C. Grev. 1. c.—Alabama, Beau¬ 
mont, Nos. 4617, 4857. No habitat given. “Perithecia rather 
small, at first slightly brown, then black, smooth, with a distinct 
papillseform ostiolum; asci linear; sporidia uniseriate, oblong- 
elliptic, 10 micr, long, uniseptate.” Cooke in Grev. XI, p. 134 
says of this, “Sporidia elliptic, continuous, fuscous. On branches 
of, Coniferae, United States. The sporidia are certainly not sep¬ 
tate in the original specimens. It is an effused Hypoxylon.” 
Hypoxylon crustaceum, Nitschke, Pyren. Germ. p. 49.—(Sec. 
Cooke not Sphagna Crustacea, Sow.) On decorticated wood, Brit¬ 
ish Columbia (Macoun.) Stroma superficial, blackening the wood 
around it both on the surface and within, more or less effused, 
tolerably thick, sooty blaek or sometimes gray-pruinose, formed 
apparently only by the connate perithecia which are about f mm. 
diam. globose and either densely crowded or looselv aggregated
