CHIVERS. — NEW SPECIES OF CHAETOMIUM. 87 



regulariter et distincte septatis, olivaceo-flavis, asperulis vestitis; 

 pilis terminalibus olivaceo-flavis, regulariter septatis, asperulis vestitis, 

 arcuatis, apice subrectis vel incurvatis; ascis clavatis, octosporis, 

 42 X 10 iJL, p. sporif. 26 n; sporidiis olivaceo-brunneis, irregulariter 

 ovatis, utrinque apiculatis, 9.8 X 5.4 /x (9.4-11 X 4.7-5.6). 



On paper, dung and other materials of various kinds from New 

 England. In cultures of old paper from Java (R. Thaxter). 



The small size anfl characteristic golden yellow color clearly dis- 

 tinguish this species from all others except Chadomium irilatcrale 

 and Chadomium fusiformc. From the former of these it differs in 

 that the spores are discharged in long black cirrhi, in the comparative 

 obscurity of the perithecial hairs at maturity, in the incurved tips 

 of the terminal hairs, and in the irregular, oval shape of its spores. 

 From the latter it differs also in producing long black cirrhi, in the 

 incurved extremities of its terminal hairs, and in the size of its spores 

 and their irregular oval shape. 



Chaetomium fusiforme, sp. nov. 



Griseum vel pallide olivaceum. Peritheciis minutis, subglobosis, 

 120 X 102 m (116-123X101-125), cirrhis carentibus; pilis latera- 

 libus numerosis, tenuibus, flexuosis, regulariter et distincte septatis, 

 olivaceo-flavis, asperulis vestitus; pilis terminalibus crassioribus, 

 asperulis vestitis, olivaceo-brunneis, regulariter et distincte septatis, 

 arcuatis, apice circinantibus vel subconvolutis; ascis clavatis, octo- 

 sporis, 48X 11M) P- sporif. 32 /i; sporidiis laete olivaceo-flavis, 

 vel olivaceo-brunneis, longis, angustis, subfusiformibus, apice rotunda- 

 tis vel apiculatis, 15.8 X 5.4 m (15-16 X 4.8-5). 



On paper from Alabama (Herb. R. Thaxter). 



The long narrow spores distinguish this form from all other species 

 of Chaetomium. In general characteristics it most nearly resembles 

 Chadomium aurcum and Chadomium trilateralc, but differs from both 

 in the long, slender, fusiform spores. 



Chaetomium trilaterale, sp. nov. 



Olivaceo-flavum. Peritheciis minutis, subglobosis, 106 X 94 ^ 

 (100-110 X 90-97), cirrhis carentibus; pilis lateralibus numerosis, 

 gracilibus, longioribus, regulariter et distincte septatis, aureo-flavis, 

 basi rectis, asperulis vestitis, apice 1-3 spiraliter convolutis, levibus; 

 pilis terminalibus irregulariter septatis, olivaceo-brunneis, asperulis
