﻿512 Ellis and Everhart : New Species of 



winter and spring of 1898, enable us to supplement and improve 



the description published in 1894. 



Acervuli erumpent through an orbicular or elliptical grayish 

 disk 1- 1. 5 mm. in diameter ; conidia oblong, straight, constantly 

 5 -septate, scarcely constricted, 35-40x7-8/^, terminal cells con- 

 ical, hyaline, intermediate cells olive-brown ; pedicels simple or 

 branched, hyaline, sometimes 3-4-septate, 70-80 X 1 — 1.5/i. 



The difference in the size of the acervuli and conidia would 

 indicate that this is distinct from the 1894 specimens, but a com- 

 parison shows that both doubtless represent the same species. 

 The original specimens do not show the orbicular gray disk, which 

 may be due to their being on the thick bark of larger limbs. 



BOTRYTIS GLAUCA E. & E. 



On bark of Qucrcns macrocarpa, Ottawa, Canada, Oct., 1897 

 (Macoun, no. 437). 



Forming smalt (2-3 mm.) subdiscoid glaucous-gray patches, 

 soon irregularly and interruptedly confluent : hyphae slender, con- 

 tinuous, 150-250 x 2-2. 5 fi, brown (under the microscope), with 

 short, straight, spreading, verticillate branches at intervals bearing 

 the clustered, elliptical, hyaline, 2.5-3 X 1.2 5- 1.5 pt conidia. 



Has the habit and aspect of Menispora glauca. 



I SARI A CAPITATA E. & E. 



On dead limbs of Plata nus occidentalism near Emma, Mo., Oct., 





1897 (Rev. C. H. Demetrio). 



Cespitose, cinereous, stems joined at the base, spreading, I nim. 

 high, formed of parallel fibers branching above and bearing at 

 their ends solitary globose hyaline conidia 3 ft in diameter form- 

 ing a subglobose ash-gray head . 3 5 mm. in diameter. 



The general appearance reminds one at a casual glance of 

 some Nectria or Ciiatrbitaria, the crowded heads simulating V en 



thecia. When
