 ANTHOSTOMA, Xitsehke. 



Pyr. Germ. p. no. 



Stronm more or less effused (diatrypoid), or pulvinate, conical or 

 hemispherical (valsoid), often only partially developed. Perithecia 

 sunk in the stroina. or in the matrix, mostly with elongated necks 

 which, in the pulvinate stroina, generally converge and are erumpent 

 together as in Valsa. Asci cylindrical or clavate, with paraphysc- 

 more or less distinct. Sporidia oblong or elliptical, continuous, brown.

Stroma effused, entirely immersed in the wood, which is blackened 

 on the surface forming elongated spots often confluent; finally blacken- 

 ing the wood more deeply, and with a black, circumscribing line. Peri- 

 thecia small, depressed-globose, entirely buried in the wood, monos- 

 tichous. loosely scattered. Ostiola exserted, minute, entire, conical or 

 hemispherical, shining, at length perforated. Asci cylindrical, short- 

 stipitate, 8-spored, paraphysate, 70x7 /*. Sporidia obliquely uniseriate. 

 obtusely-fusiform, straight or rarely subinequilateral, becoming dark 

 brown, 12-14 x 5-6 /JL.

Stroma effused, thin, crustaceous, overspreading the surface of the 

 inner bark, and throwing off the epidermis for 6 inches or more in ex- 

 tent, brownish at first with a rufous tint, finally darker, less than | mm. 

 thick and easily overlooked, beins: of about the same color as the bark. 







surface minutely papillose-roughened by the slightly prominent, sub- 

 hemispherical or obtusely-conical ostioia. Perithecia covered above 

 by the stroina, small, less than \ mm. diain., depressed-globose, thin- 

 walled, white inside, narrowed directly into the ostioia. which are 

 sometimes faintly radiate sulcate. Asci clavate, 50-60x10 // (p. sp. 

 40 x 10 /JL), short-stipitate, with imperfectly developed paraphyses. 

 Sporidia snbbiseriate above, short-elliptical or subglobose. 7-1 Ox 

 5-8 fji, becoming nearly black. 1-2-nucleate. but not septate.
