Quercus; on beech and Liriodendron, Pennsylvania (Everliart); o: 

 various dead limbs, Florida (Calkins). 



The perithecia appear first in the middle of the stroma, and sprea^ 

 towards its margin, which thus remains for some time sterile. Th 

 perithecia are larger than in IT. perforatum and more evenly effusec 

 and the stroma is of a brighter color. At first, and around the margii 

 of the stroma, the pei-ithecia stand quite separate, but they are final! 

 closely packed.

Stroma suborbicular, thin (1 mm.), flat, |-1 cm. diam., sometime 

 continuous or interruptedly confluent for 5 or more cm., purplish rus< 

 color, with a thin, sterile margin at first, but this generally disappears 

 leaving the margin abrupt and rounded, surface papillose from th 

 slightly prominent, rounded apices of the perithecia, which are in 

 single layer, subglobose, small (I mm.), numerous, but not crowded s 

 as to be much compressed, covered above with a thin stromatic laye 

 which is of a dirty greenish-yellow within, at least in the young, fres 

 growing state, and finely white-punctate from the minute ostiola, bu 

 both the internal yellow color and the white-punctate ostiola finall; 

 disappear. Asci (p. sp.) 60-65 xl p., with a stipitate base 30-40 ; 

 long. Sporidia uniseriate, elliptical or subnavicular, opake. 7-8:

On bark of dead limbs of some deciduous tree, Florida (Calkins 



The general appearance, color and mode of growth is that c 

 H. rubiginosum, (Pers.), from which it differs in its yellow stroma 

 smaller perithecia and sporidia; nor can it be referred to any of th 

 species already enumerated, having the internal substance of th 

 stroma yellow. The yellow stroma and smaller sporidia will also dis 

 tinguish this from H. perforatum, (Schw.). 



H. Fendleri, Berk. Grev. XI, p. 132. 



Effused, determinate, thick, rugose, yellow, finally black-brow 

 ("atrofuscum"). Perithecia distinct, globose, elevated, with blac 

 papilliform ostiola. Asci cylindrical. Sporidia narrow-elliptica 

 straight or somewhat curved, dark, 12-13x4 fi. Somewhat like a 

 effused state of H. multiforme or a thick form of II. rubiginosum, a 

 length nearly black. 



On rotten wood, Venezuela. Extra limital, but will probably b 

 found in Central America.
