Spots obsolete, hypophyllous ; niycelia spreading in thin film-like 

 overgrowth, fugacious ; perithecia punctiform, scattered, flat-dis- 

 coidal or conspicuously compressied into scale form, 170-220 

 (aver. 200 /x) diam., black; perithecial wall membranaceous, cells 

 small and irregular, sometimes more or less radiating, 4-8 wide ; 

 appendages numerous, 200-300 altogether, filiform, simple, 

 smooth, thin- walled, 35-200^11 long, 4-1 1 septate throughout, the 

 basal half yellowish-brown, 6-7 ^u, across, gradually narrowed 

 toward the apex, 2-2.5 across near the hyaline ends, apex coiled 

 spirally ; asci 3-5 to one perithecium, ellipsoid or ovoid, rounded 

 at the apex, beaked, below, walls rather thick but brittle, 65-75 

 X 37-50 IX ; ascospores 4-5, ellipsoid, ovoid, or ovoid'-reniform, both 

 ends rounded, yellowish, unicellular, granular inside, 28-35 X 12- 

 15 rarely 45 X i8/x. 



On Fagus sylvatica var. Sieholdi. 



Locality and distribution : Not given. 



Notes : In a letter from Mr. Hara, received shortly before by 

 the writer, a very peculiar habit of this fungus is described, which 

 caused him to determine to raise this as a species. He found that 

 the perithecia at maturity behaved always to turn over on their 

 heads holding the substratum with their appendages exactly like 

 the perithecia of Phyllactinia corylea do with the second appen- 

 dages. He proposes a new subgenus Asterothecia to which the 

 species belong, characterized by another noteworthy peculiar form 

 of flattened perithecia.
