Rot Penicillium

<i> <b> Penicillium expansum </b> </i> rot on white grape berries.
Berries affected by <i> <b> Penicillium expansum </b> </i> wet rot have turned beige.
Detail of bluish spore pads formed on the surface of berries affected by wet rot with <i> <b> Penicillium expansum </b> </i>.
Detail of bluish spore pads formed on the surface of berries affected by wet rot with <i> <b> Penicillium expansum </b> </i>.
Some berries are more or less shriveled, some have taken on a rather dark purplish hue. <i> <b> Penicillium expansum </b> </i> (Penicillium rot)
Several white spore pads, gradually taking on a blue tint, develop on this rotten berry. <i> <b> Penicillium expansum </b> </i> (blue rot)
This rotten, shriveled berry is covered with spore pads of <i> Penicillium expansum </i>. (<b><i>Penicillium</i> </b> rot)
There are several berries that are particularly affected by blue rot caused by <i> <b> Penicillium expansum </b> </i>. The more or less shriveled berries are covered with often old spore-bearing pads of a dark gray-green color.
A proximité de baies botrytisées, on note plusieurs baies particulièrement affectées par la pourriture bleue due à <b><i>Penicillium expansum</i></b>. Les baies plus ou moins ratatinées sont couvertes de coussinets sporifères souvent anciens à la couleur vert gris sombre.
The heart of this fully botrytised cluster is more or less invaded by a <i> Penicillium </i> sp. : a dark green mold is recognizable in the center of this figure.
A colony of <b> <i> Penicillium </i> sp. </b>, dark green in the center and yellow in the periphery, covers several berries affected by gray mold.
Penicillium Bot 4
The heart of this fully botrytised cluster is more or less invaded by a <i> Penicillium </i> sp. : a dark green mold is recognizable in the center of this figure.
Mycelium and conidiophores of <b><i> <b> Penicillium glabrum </b> </i> have formed on a rotten berry in the heart of a cluster. (bunch mold)
In the heart of the cluster, one can even observe the sporulation of <i> Penicillium </i> on the raffle. <i> <b> Penicillium glabrum </b> </i> (bunch mold)
