on green bean pods the spores of Gloeosporium castagna Mont., which 

 had proved to be very virulent on the leaves of the silver poplar, but 

 obtained no infection. He therefore concluded that gloeosporial forms 

 are independent species and have their own host plants. Southworth 

 (1890:48) attempted unsuccessfully to infect bean pods with the holly- 

 hock-anthracnose fungus, Colletotrichum althaeae Southw. (C. malvarum 

 [A. Br. & Casp.] Southw.), but was successful with C. lindemuthianum. 

 Halsted (1893 b: 327, 329), in connection with his cross-inoculation work, 

 obtained good infection on detached bean pods with Colletotrichum sp. 

 from the eggplant, and with Gloeosporia from pepper, apple, and tomato; 

 also (1893 d: 248) with Colletotrichum lagernarium (Pass.) E. & Hals, 

 from the watermelon. Sheldon (1904:132-135) inoculated wax-bean 

 seedlings, bean plants in blossom, and bean pods on the plants, and also 

 six different cucurbits, with spores of C. lagernarium from pure cultures 

 obtained from a watermelon fruit. Infection was obtained on the cucurbits 

 in most cases, but the beans for the most part were free from evidence of 

 infection. Sheldon did find, however, spots bearing spores both on the 

 beans inoculated by him and on those used as checks. He decides that 

 it is not safe to conclude from his results that the anthracnose fungus on 

 the beans is the same as that on the melons and the gourds. Edgerton 

 (1910:41) obtained no infection on young bush beans sprayed with spores 

 of the fig anthracnose (Glomerella fructigena [Clinton] Sacc.) and of the 

 pepper anthracnose (G. piperata [E. & E.] S. & S.), and no infection on 

 freshly picked bean pods placed in a moist chamber and inoculated with 

 a culture of the rose-anthracnose fungus (Gloeosporium rosae Hals.); 

 although in every case good infection was obtained with the bean-anthrac- 

 nose fungus on the beans used as a control. Bean seeds wet with a suspen- 

 sion of spores of the fig- and the cotton-anthracnose fungus were some- 

 what infected. Spores of the fig-anthracnose fungus were being produced 

 in abundance on seed that had rotted in the ground, and the semi-living 

 cotyledons of the germinating beans were attacked by both fungi. The 

 spots did not develop further, however, while in the case of seeds treated 

 in the same way with spores of the bean-anthracnose fungus the cotyledons, 

 and later the plants, became higlily infected. Taubenhaus (1911:198) 

 reports success in obtaining infection on pods of pole and bush lima beans 

 in the field from puncture inoculation with spores of species of Gloeo- 

 sporium from sweet pea, apple, and mandrake, or may-apple, and with
