In a certain stage of growth the black stroma-like spots are not visible,
but there are merely a few creeping flooci at the base of the perithecia, these
gradually increase in number, so as at length to form a thin darlc stratum.
The species may be recognised in any state by the fusiform spores, the middle
joint of whicli is swollen. Besides the true paraphyses there are iointed
threads in the perithecia.—
