Perithecia thickly scattered, subepidermal, penetrating the epi- 

 dermis with elongated ostiola, spherical or ellipsoidal, 300-400/* 

 in diam., 280-372 fx in height, the inside of ostiolum and adjacent 

 area covered by short periphysatic hairs, containing few asci ; 

 asci cylindrical or ovoid, short stipitate, 140-200 X 3 7-46 para- 

 physate ; ascospores biseriate or irregular, hyaline and unicellular 

 at juvenile stage but quickly developing into 4-celled dark-colored 

 mature spores, the contents of which are first characteristically 

 represented by comparatively large shiny oil globules, soon dis- 

 appearing and replaced by granular protoplasm scarcely permitting 

 the light to pass through, 52-65 X 13-17 v>, cylindrical, not con- 

 stricted at the septum ; gelatinous envelope none. 



On twigs of Morus alba (common). 



Type localities: Gifu-ken (prefecture), Kaidzu-gun Kaisai-

Illustrations : 3 black and white lithographic figures showing 

 detailed structure of the fungus. 



The juvenile acospores very much resemble those belonging 

 to other genera, but close examination of mature spores will 

 show the characteristics of the genus Massaria.
