﻿360 Earle : New or Noteworthy 



Following plant lice exudations on living leaves of Magnolia 



Virginiana, Auburn, Ala., April n, 1896. Underwood & Earle. 

 An undeveloped Antcnnaria occurs on the same leaves. 



This is near M. applanatus Mont., but it seems to differ in the 

 depressed ostiolum, the smaller asci and larger more frequently 

 septate spores. Much confusion has resulted from the hasty and 

 unwarranted reference of American material to foreign species. It 

 seems better in every way to consider our species distinct until the 

 contrary is clearly proven. 



AXTHOSTOMELLA SPHAEROTHECA sp. IIOV. 



Stroma thin, black, crust-like, containing 1-6 or 8, prominent, 

 subconic perithecia, perithecial wall poorly developed, ostiolum 

 very short-papillate : asci nearly orbicular, about 20 x 18 ft, apara- 

 physate, very thin and delicate, soon deliquescing and liberating 

 the spores : sporidia oval or spindle-shaped, often inequilateral, 

 ends acute, light fuliginous but transparent, the center usually oc- 

 cupied by a large oval vacuole, i6-i8x 5-6//. 



On dead petioles of Sabal Adansom, Tusk. 

 1897. G. W. Carver (no.. 101). 



Externally this clearly resembles A. minor E. & M., but the 

 asci in that species are cylindrical, and the spores only 7-$ f* lon ^ 

 The quickly evanescent asci are often hard to detect, a hasty ex- 

 amination giving the impression of a Sphaeropsis. The black, thin, 

 crust-like stroma, and imperfectly developed perithecia suggest the 

 Dothidiales, and it is possible that the species may ultimately be 

 placed in Auerswaldia. 



BOTRYOSPHAERIA ArUNDINARIAE Sp. nOV. 



Stroma erumpent, pustular, bordered by the ruptured epider- 

 mis, small, usually about 1 mm., irregularly oval, black, stromattc 

 material scanty : perithecia kw, 2 or 3 to 6 or 8 in each stroma, 

 soon partly exposed, black, carbonaceous, about 300/;, with papiHi- 

 form ostiolum: asci elongate, subcylindric, long-stipitate, 120 or 

 more by 10-12//, paraphyses abundant, vague, minutely granular, 

 4-6// in diameter: sporidia subdistichous, continuous, hyaline, 

 often granular and vacuolate, oval, often curved or inequilateral.
