'Nummular ia anthracodes (Fr.) Cke. Stroma widely effused, developing in 
the cortex under the outer cork layer (which exfoliates, exposing the 
fructification), closely attached over entire surface to the bark beneath, 
1 to 2 millimeters thick, brittle smoky black, shining when weathered, 
smooth, covered with small craterlike ostioles ; ostioles slightly erumpent ; 
perithecia oval to cylindrical, densely crowded in one layer, reaching 
1,500 ix in height by 300 fi in diameter; asci clavate-cylindrical, 100 to 
110 by 6 to 8 ii ; spores 8, uniseriate, fusoid-navicular, light brown to 
translucent, becoming dark brown and opaque, 15 to 18 by 6 to 8 /*, occa- 
sionally reaching 25 by 8 \i ; expelled in glutinous masses about the ostiola 
below the exfoliated outer bark. On tapping wounds, mistletoe burls, etc., 
Amazon region. 
A 7 , cincta Ferd. and Wgl. On old tapping bark, Amazon region. 
K. commixta Ptehm. On dead bark of fire scars and on tapping cuts attacked 
by borers. Amazon region. 
A. pith odes (B. and Br.) Petch. Described in connection with the diseases 
of Hevea in Ceylon. Closely related to A. anthracodes. The species was 
originally referred to the genus Diatrype and by Saccardo to Anthostoma.

species.

filamentous, hyaline, about 2 fi thick. On Hevea, Brazil.
