Final diagnosis


Athelia rolfsii (Sclerotium rolfsii, Rots in Athelia)

The fungus also invades the roots which turn brown and rot. Its mycelium is visible in places. <b> <i> Sclerotium rolfsii </i> </b> (southern blight)
The white mycelium is now proliferating on the stem. <b> <i> Sclerotium rolfsii </i> </b> (southern blight)
The mycelium proliferates on the stem, even if it is buried. <b> <i> Sclerotium rolfsii </i> </b> (southern blight)
The mycelium proliferates on the stem, even if it is buried. <b> <i> Sclerotium rolfsii </i> </b> (southern blight)
Wet, soft rot is clearly visible on this mature fruit. Mycelium is gradually covering it. <b> <i> Athelia rolfsii </i> </b> (<i> Sclerotium rolfsii </i>, <i> Sclerotium </i> rot, southern blight)
<b> <i> Athelia rolfsii </i> </b> (<i> Sclerotium rolfsii </i>, southern blight) partially colonized this fruit. A moist, concave lesion is clearly visible, the epidermis is wrinkled and locally ruptured. Mycelium and sclerotia are gradually covering it.
Sclerotium1
We can easily distinguish the loops of anastomosis of this basidiomycete on its mycelium. <i><b>Athelia rolfsii</b></i> ( Sclerotium rolfsii , southern blight)
Sclerotium2
On the mycelium of <i> <b> Athelia rolfsii </b> </i> sclerotia 1 to 3 mm in diameter are formed, which gradually turn brown (eg <i> Sclerotium rolfsii </i>, southern blight ).
