Final diagnosis


Sclerotinia sclerotiorum, Sclerotinia minor

Beige alterations, partially covered with white woolly felting. <i> <b> Sclerotinia sclerotiorum </b> </i> (sclerotinia, white mold)
<i><b>Sclerotinia sclerotiorum</b></i> (white mold)
A longitudinal cut of the basal part of the stem, located at the level of a beige, dry chancre, reveals black sclerotia in the marrow. <b> <i> Sclerotinia sclerotiorum </i> </b> (sclerotinioses, <i> Sclerotinia </i> basal stem canker)
<b><i>Sclerotinia sclerotiorum</i></b> (white mold)
<b><i>Sclerotinia sclerotiorum</i></b> (sclérotinioses, <i>Sclerotinia</i> basal stem canker)
A large black sclerotia has formed on the surface of this young green fruit. White mycelium can be distinguished in places. <b> <i> Sclerotinia sclerotiorum </i> </b>
The sclerotia of <i> <b> Sclerotinia sclerotiorum </b> </i> are usually black, irregular in shape, and rather large (2.5-20 mm) (sclerotinia, <i> Sclerotinia </i> drop , watery soft rot)
The production of apothecia on sclerotia materializes the teleomorph of <b> <i> Sclerotinia sclerotiorum </i> </b>. The color of these fruiting bodies is variable (yellowish white, light brown to slightly brown). Sclerotinia (<i> Sclerotinia </i> drop, watery soft rot)
A few apothecia of <i> <b> Sclerotinia sclerotiorum </b> </i> have formed on sclerotia of this fungus present on the soil surface. (sclerotiniosis) (Thibaut CHESNEAU)
