Colletotrichum graminicola

In maize a variety of stain procedures were used with light microscopy to demonstrate that papillae formed in response to attempted infection by Colletotrichum graminicola and Helminthosporium maydis are composed of lignin (Cadena-Gomez and Nicholson, 1987 Figures 4-7 and 4-8).
