Some New Parasitic Fungi of Japan 



By 

 Mitsutaro Shirai and Kanesuke Kara. 



In the course of studying Japanese fungus flora, we have 

 met with many species of parasitic fungi not yet described. In 

 the following paper, we intend to describe and illustrate such 

 new species of fungi as we had opportunity to examine in the 

 Botanical Laboratory of Agricultural College of the Imperial 

 University at Komaba. 



Lophodermium Chamaecyparisii Shirai et Hara. nov. sp. 



Perithecia one to each scale or several in groups, subepider- 

 mal, forming minute black elevated pustules, elliptical or roun- 

 dish, longitudinally dehiscent, 500-800 // long, 300—500 jj. broad, 

 300—350 /i high ; asci cylindrical or clavate, obtusely pointed 

 at the apex, 8-spored, 50-60 jj- long, 5-5.5 n broad ; spores in 

 a parallel fascicle, acicular or filiform, unicellular, 40—50 fi long, 

 0, 5-0, 7 p- broad, hyalin ; paraphj^ses filiform, slightly inflated 

 at the apex, simple, or branched at the top.

Asterula Chamsecyparisiis Shirai et Hara nov. sp. 



Mycelium epiphyllous, radiate, thready, brown, 3—5 y. broad, 

 with numerous septa ; perithecia, seated on mycelium, scatter- 

 ed or gregarious, patelliform, with a small roundish aperture in 

 the projected center, and a circular groove around the opening, 

 dark brown, membranacetis, radiate in structure, smooth on the 

 margin, 150-210 /j. in diameter ; cells of peridium square or
