1880 C. E. Bessey Bot. 289 In this stage, which is called the Sphacelia stage, it produces a multitude of conidia.

1882 S. H. Vines tr. J. von Sachs Text-bk. Bot. (ed. 2) 317 The conidia can germinate at once and immediately again detach conidia, which..again produce a sphacelia in other Grasses.

1909 B. M. Duggar Fungous Dis. Plants xi. 245 The surface mycelial areas are thrown into folds and numerous short conidiophores arise, bearing small ovate conidia. This is known as the sphacelial stage.

1938 G. M. Smith Cryptogamic Bot. I. xii. 453 This is followed by a progressively upward metamorphosis into compact tissue until the whole mycelium has been changed into a sclerotium that is capped with remnants of the sphacelial tissue.

1976 G. C. Ainsworth Introd. Hist. Mycol. vii. 187 The major contribution of L. R. Tulasne in his classic paper in 1853..was to demonstrate that the sphacelial phase, the sclerotia, and the ascocarps were all stages of one fungus, Claviceps purpurea.
