6. Chaetomium funicola Cooke, Grevillea 1: 176. 1873. 
Chaetomium setosum Ellis & Ey. Am. Nat. 31: 340. 1897. 
Chaetomium bartholomaei Sacc. & Syd. in Sacc. Syll. Fung. 14: 490. 1899. 
Mycelium superficial, white, branched, indistinctly septate; perithecia 
scattered or gregarious, broadly ovoid, 130-200x100-145 mic., dark- 
brown, opaque, thin, membranous, clothed on all sides with hairs; apical 
hairs of two kinds, simple and branched; simple hairs lanceolate, some¬ 
times extending over 300 mic. above the perithecium, septate, tapering 
from the scabrous, dark-brown base to the smooth, or slightly scabrous, 
pale tip; branching hairs few in number or forming a mass 175 mic. 
above the perithecium, sometimes straight and simple for 160 mic., 
septate, usually scabrous throughout, dark-brown at the base to pale- 
brown at the tip, with numerous ramifications, sometimes regularly 
dichotomous, more often irregularly branched, branches 10-20 mic. long; 
lateral hairs simple, almost straight, comparatively short, 3-4 mic. wide, 
septate, tapering from the scabrous, pale-brown base to the smooth, 
hyaline tip; rhizoids simple, flexuous, slender, 2-5 mic. thick, non-septate, 
smooth, pale-brown; paraphyses and asci not observed; spores simple, pale 
olivaceous-brown, limoniformis, 3-7x3-4.5 mic. 
Habitat: On old broom, straw, and damaged hay. 
Distribution: New York to Ohio and Kansas. 
Illustration: PI. II, f. 13-18. 
Type Locality: Albany, New York. 
Distinctive Characters: Small perithecia, with both simple and 
branched hairs. 
Notes: Mycelium on agar white at first, the center becoming pale-green to black, concentrically 
zoned with a gray zone between the center and the outside, the darker center bearing perithecia first; 
even the light outside zone is zoned. 
Plants cultivated in the laboratory, March 23, 1917, on potato hard agar, the culture made Feb. 27, 
1917, from specimen on straw, collected by the author, near Georgetown, Dec. 3, 1916. 
FAMILY 2. FIMETARIACEAE. 
Perithecia scattered or aggregated, superficial or deeply sunken in 
the substratum, and often erumpent at maturity, slightly transparent to 
black and opaque, with wall thin and membranous to coriaceous, usually 
without a stroma (true of all genera contained in this paper), but, if with 
stroma, the perithecia sunken with projecting papilliform beaks. Asci 
usually very delicate, surrounded by long paraphyses or intermingled with
