MORPHOLOGY AND LIFE HISTORY OF SOME ASCOMYCETES 443 
In order to facilitate the association of the new name with the well 
known disease of the fig, the specific name, Bolleana, applied to the conidial 
stage is used; and the name Sphaerella Bolleana is suggested with the 
following diagnosis. 
Mycosphaerella Bolleana^ n. sp. Perithecia mostly hypophyllous, 
partly embedded in the leaf tissue, erumpent, 60-105 X 55-95 M» black; 
ostiolum papillate; asci cylindrical to club-shaped, almost sessile, eight- 
spored; spores club-shaped to cylindrical, two-celled, 17-20 X 3.5-5.5 m> 
hyaline. 
Spermogonia produced in the autumn, hypophyllous, embedded in the 
leaf tissue, with only the ostiolum emergent, ovate, 40-90X30-75^1; 
spermatia small, rod-shaped, 2-3 X i fx, hyaline. 
Conidial stage: Spots ferrugineous to olive-brown, irregular, 2-5 mm. 
in diameter; conidiophores hypophyllous, simple, solitary or fasciculate, 
slightly geniculate, brownish olive, continuous or sparingly septate, 50-90 
X5-6/X; conidia olive-brown, clavate to fusoid, 32-53X6-8^1; i- - 
5-septate. 
Conidial stage parasitic on the leaves of Ficus carica L. 
Perithecia and spermogonia on the dead fallen leaves. 
Peritheciis hypophyllis, semiimersis, sparsis, ovatis, 60-105 X 55-95 Ml 
ostiolis prominulis; ascis cylindricis vel clavatis, brevissime stipitatis, 
aparaphysitis, 35-40 X 11 jjl, octosporis; sporidiis hyalinis, clavatis, 17-20 
X 3.5-5-5 M, i-septatis. 
Spermogoniis autumno, hypophyllis, immersis, emergentibus, puncti- 
formibus, nigris, ovatis, 40-90 X 30-70 m; spermatiis minutis, cylindricis, 
2-3 X I iu, hyalinis. 
Hab. in foliis dejectis Fici caricae. 
Status conidicus: Maculis brunneis vel olivaceo-fuscis, irregularibus, 
2-5 mm. lat., interdum subeffusis; hyphis hypophyllis, solitariis aut 
fasciculatis, apice geniculatis, continuis aut septatis, 50-90 X 5-6 /z; coni- 
diis clavatis vel tereti-fusoideis, 32-53 X 6-8 /x, apice obtusioribus, chlorino- 
olivaceis, i — 5-septatis. 
Hab. in foliis vivis Fici caricae.

2 The technical description bears the generic name Mycosphaerella Johanson, since 
this name is used in many recent systematic works; though it seems desirable that Sphaerella 
Ces. et de Not. may be one of the genera conservanda in the report of the committee ap- 
pointed by the Botanical Congress at Vienna in 1910.
