Germinating teleutospore at a later stage, the promycelium having become divided into four segments, and comparatively stout tubes emitted from each seg-ment. 125. Two germinating teleutospores, in the one on the left only the two median seg- ments of the promycelium as yet bear sporidiola. 126. Germinating teleutospore with stout elongated and contorted filaments arising from the promycelial cells, those from the two median cells ultimately givingrise to abnormally small sporidiola. 127. Germinating teleutospore in which the upper two promycelial cells have produced sporidiola, while in the third from the apex the format
