Inside the perithecium, the developing asci are immersed in maternal tissue. |
|
When mature, a perithecium contains several hundred asci that are ejected by turgor pressure. |
|
Features of the spores and the perithecium in which they occur suggest that this may be a fossil species of Savoryella. |
|
All these steps take place in a specialized fruiting structure, the perithecium. |
|
Since the perithecium grows out into the medium from the hymenium after nuclear pairing, this is ascohymenial development. |
|
The asci are unitunicate, 8-spored with deliquescent base so that mature asci lie free in the perithecium at maturity. |
|
To make a completely accurate diagnosis, the pathogen would need to be isolated, cultured and forced to produce a perithecium. |
|
A spore leaving the perithecium travels nearly straight up at first. |
|
Stalk-cell of perithecium greyish, about as long as maximum width, its surface inconspicuously striate, separated from cell below by distinctly oblique septum. |
