SYNOPSIS OP THE NORTH AMERICAN SPECIES 
OF XYLARIA AND PORONIA. 
BY J. B. ELLIS AND B. M. EVRRHART. 
Xylaria, Hill. Hist. Plant (1773), pp. 62 and 63. 
Stroma erect, round, clavate or subglobose, mostly stipitate, sube- 
rose or coriaceous; peritlieciaadnate or immersed in the stroma, coriaceo- 
carbonaceous ; asci subcylindrical ; sporidia ovoid or subnavicular, 
continuous, dark. 
A. Xyloglossa. Capitulum everywhere fertile, stem smooth. 
a. Capitulum clavate , stem slender , elongated. 
1. Xylaria euglossa, Fr. Xov. Symb., p. 124. 
Stroma clavate, thickened above, obtuse, smooth, clay colored, black- 
punctate by the minute ostiola, within whitish-cinereous, becoming darker 
towards the surface; perithecia entirely immersed, globose, black, stipe 
slender, elongated, glabrous, turning black. Found in Costa Rica by 
Oersted. 
This species resembles Geoglossum difforme , but is larger, 3—4 inches 
high and, in the dry state, at least, is longitudinally rugose, often arcu- 
ate-incurved or twisted and almost as hard as stone; stipe over an inch 
long, but scarcely exceeding a line in thickness, equal, glabrous, longi¬ 
tudinally rugose when dry. The club in form and color resembles Clava- 
ria ligula , but is paler, properly black, but appearing as if smeared over 
with alutaceous-clay color, obtuse above and distinct from the stipe; 
asci slender, linear, evanescent; sporidia uniseriate, oblong, acute at 
each end, continuous, opaque, occasionally curved. 
2. Xylaria protea, Fr. 1. c..p. 125. 
Stroma suberose-indurated, lanceolate, obtuse, wrinkled, bare, white 
within, stipe slender, equal, glabrous; perithecia globose, subimmersed, 
peripheric, depressed-hemispheric, with rather prominent ostiola. On 
trunks in Costa Rica. Oersted. 
Resembles X. corniformis , Fr., which, however, differs in its obsolete 
stipe and villous base, while this, like the preceding species, has the stipe 
slender, very smooth and varnished and so fragile that there is hardly a
