Bean Anthracnose 113 



and of the related genus Gloeosporium similar in appearance, but 

 also the diseases produced by species of the two genera are similar in 

 character. 



Saccardo (1878), in his description of the fungus, gave it the name 

 Gloeosporium lindemuthianum Sacc. & Magn. after Lindemuth, who 

 discovered the fungus in 1875. Scribner (1888:364) described the presence 

 of setae in the acervuli which were present on most specimens sent him 

 from several States, and thought it probable that the generic name of 

 the fungus should be changed to Colletotrichum. The following year 

 Briosi and Cavara (1889) named the fungus Colletotrichum lindemuth- 

 ianum (Sacc. & Magn.) Bri. & Cav., and distributed it as such. The 

 same year Scribner (1889), again finding setae in the acervuli, placed the 

 fungus in the genus Colletotrichum and published it as Colletotrichum 

 lindemuthianum (Sacc. & Magn.) Scribner. The name given by Briosi 

 and Cavara stands, although it is evident from much subsequent cultural 

 work that the presence or absence of setae is not a character of sufficient 

 stability to serve as a basis for the determination of generic position. 

 Kriiger (1913:294-303) was able to develop setose and non-setose cultures 

 of this fungus at will, finding that a number of factors, such as age of the 

 culture, and nature and moisture content of the substratum, were control- 

 ling agencies. He, however, designates the conidial form as Gloeosporium 

 (subgenus Colletotrichum) lindemuthianum Sacc. & Magn. 



Halsted (1893d), after making cross-inoculations on bean and water- 

 melon, decided that the anthracnose fungi in these two hosts were the 

 same, and used the name Colletotrichum lagernarium (Pass.) Ellis & Hal- 

 sted, including in the synonymy the names that had been applied to the 

 organism causing melon anthracnose and bean anthracnose, respectively. 

 Shear and Wood (1913:46) found perithecia producing asci and ascospores 

 in cultures made from an anthracnose spot on a bean pod, and they refer 

 their fungus to Glomerella lindemuthianum Shear n. comb. Kriiger (1913: 

 311), although he did not find perithecia, designates the fungus as Glomerella 

 lindemuthianum Shear n. comb. Edgerton (1915:255-256) questions 

 whether any perithecial stage of this fungus has ever been seen, and sug- 

 gests that Shear and Wood might have been working with one of the 

 saprophytic forms occurring commonly on bean pods. He believes 

 the fungus should be considered as a species of Colletotrichum until 

 further evidence supports a different view.
