The perithecia are situated below the bark, they are solitary, or, more frequently, united (at most 10—15 together) into loose, most oftenlv elongated clusters, globulose, blackish, about 200—250 // in diameter ; their walls 16—20 // thick ; they consist of 4—5 layers of about 4 //, broad cells, which are brown and of somewhat thickened walls, all seemingly compressed in a cross-section of the fruit-body ; their ostiolum elongated, almost cylindrical, or apically tapering, of a wide aperture, rigid, straight, or curved, its length vary, according to the thickness of the substratum above the perithecium, between halfth to twofold the diameter of the perithecium, indeed, it may even surpass this value ; about 80 [i at their base, arising in groups composed of 1—2 compact layers of 10—15 units through mainly the transverse crackings of the thicker twigs, they may also pierce the bark, singularly and irregularly dispersed. The asci are clavate, of thickened walls, pedicellate, 30—40x5,3—6 /n (p. sp.: 16—24x5,3—6 /<), 8-spored; the spores are either arranged in 2—3 layers on the upper part of the ascus or situated irregularly within the ascus, they are allantoid, hyaline, of a 7,2—9x 1,4—1,6 [J. : the paraphysis-like hyphae are about 2 thick, usually not ramifying, septate, 1—-2,5 times longer than the asci. The ascus-bearing layer completely fills the inside of the perithecium. On the dry twigs of Fumana procumbens (Dun.) Gr. et Godr.
