Choanephora cucurbitacearum

Piment-Plante
<i><b>Choanephora cucurbitarum</b></i> gradually colonizes these chilli leaves by their altered tip. Its mold is clearly visible in places. (rot in Choanephora)
On this mature, weathered pepper, the many sporocysts (or sporangia) formed by <i><b>Choanephora cucurbitarum</b></i> can be clearly distinguished. This fruit is somewhat moist, dark yellow, soft and more or less shriveled. (rot in Choanephora)
This young pepper is completely rotten. The moist, dark green, deliquescent tissues gradually become covered with the characteristic mold of <i><b>Choanephora cucurbitarum</b></i>. It should be noted that on peppers this fungus frequently penetrates the fruits via the remains of senescent floral parts. (rot in Choanephora)
<i><b>Choanephora cucurbitarum</b></i> is gradually colonizing this withered and necrotic eggplant leaf. Its mold is now visible in places. (rot in Choanephora)
This eggplant leaf is completely invaded by <i><b>Choanephora cucurbitarum</b></i> which sporulates there abundantly. (rot in Choanephora)
Detail of sporocysts in place on a rotten portion of eggplant leaf. <i><b>Choanephora cucurbitarum</b></i>. (rot in Choanephora)
This eggplant is completely rotten and mummified. The characteristic dense mold of <i><b>Choanephora cucurbitarum</b></i> completely covers it. (Choanephora rot, cucurbit flower blight
This rotten, brown-hued eggplant fruit is entirely covered by the dense sporulation of <i><b>Choanephora cucurbitarum</b></i> . (rot in Choanephora)
A large moist, brown to brown lesion gradually invades this transversely cut eggplant. Note the sporulation of <i><b>Choanephora cucurbitarum</b></i> on the cut part of the fruit. (rot in Choanephora)
<i><b>Choanephora cucurbitarum</b></i> has rotted the remains of the floral parts of this young cucumber fruit on which it sporulates profusely. (Choanephora rot, cucurbit flower blight)
<i><b>Choanephora cucurbitarum</b></i> produces a characteristic rather airy blackish mold on this fruit. (Choanephora rot, cucurbit flower blight)
On this zucchini plant, a fruit is almost entirely rotten by <i><b>Choanephora cucurbitarum</b></i>. Part of the soft tissue has collapsed. (Choanephora rot, cucurbit flower blight)
After settling on the tip of this young fruit, <i><b>Choanephora cucurbitarum</b></i> caused a wet, brown rot and sporulated profusely on the damaged tissues. (Choanephora rot, cucurbit flower blight)
After settling the petals, <i><b>Choanephora cucurbitarum</b></i> generates a brown rot at the end of this young zucchini fruit and sporulates there abundantly. (Choanephora rot, cucurbit flower blight)
Young zucchini fruit completely rotten by <i><b>Choanephora cucurbitarum</b></i>. The moist, brown tissues gradually decompose and are covered by a blackish mold. (Choanephora rot, cucurbit flower blight)

Melon
Young patisson on which <i><b>Choanephora cucurbitarum</b></i> has settled from senescent sepals. The weathered tissues are covered by the characteristic mold that it forms. (Choanephora rot, cucurbit flower blight)
The tissues invaded by <i><b>Choanephora cucurbitarum</b></i> are translucent and dark while a mold partially covers them; it will gradually take on a purple to black tint.

Young patisson on which <i><b>Choanephora cucurbitarum</b></i> has settled from senescent sepals. The weathered tissues are covered by the characteristic mold that it forms. (Choanephora rot, cucurbit flower blight)
Young patisson fruit fully rotted by <i><b>Choanephora cucurbitarum</b></i>. Weathered tissues gradually decompose and are covered by a black "pinhead" mold. (Choanephora rot, cucurbit flower blight)
Several lower cabbage leaves show large necrotic lesions around the leaf blade. <i><b>Choanephora cucurbitarum</b></i> (Choanephora rot)
<i><b>Choanephora cucurbitarum</b></i>, after settling on the periphery of the leaf blade of a cabbage leaf, colonizes the latter gradually; altered tissues that are moist and soft at first turn brown and progressively become necrotic. (rot in Choanephora)
Cabbage leaf completely colonized by i><b>Choanephora cucurbitarum</b></i> which has strongly sporulated on the damaged tissues. (rot in Choanephora)
Okra
A damp, brown to black rot, depending on the location, has completely invaded this okra inflorescence. <i><b>Choanephora cucurbitarum</b></i> (Choanephora rot)
The remnants of the petals of this young okra fruit show a black, wet rot. <i><b>Choanephora cucurbitarum</b></i> gradually covers them with its blackish mould. (rot in Choanephora)
The remnants of the petals of this young okra fruit are beginning to rot and become covered with the characteristic mildew of <i><b>Choanephora cucurbitacearum</b></i> . (rot in Choanephora)
Several coriander leaves are more or less affected by progressively browning moist lesions. <i><b>Choanephora cucurbitarum</b></i> (Choanephora rot)
On these two coriander leaves completely altered by a damp and dark rot, <i><b>Choanephora cucurbitarum</b></i> sporulated well. (rot in Choanephora)
<i><b>Choanephora cucurbitarum</b></i> has settled on the weathered tissues of the blade tip of this chive leaf. (rot in Choanephora)
<i><b>Choanephora cucurbitarum</b></i> is also able to establish and sporulate on any injured leaf tissue. (rot in Choanephora)
Bean pod invaded by <i><b>Choanephora cucurbitarum</b></i>. Note the numerous pinhead structures. (rot in Choanephora)

Sporocyst (or sporangium) of <i> <b> Choanephora cucurbitarum </b> </i> observed with a binocular magnifying glass
Observation under an optical microscope makes it possible to distinguish the primary and secondary vesicles which partly constitute the sporocyst. <i> <b> Choanephora cucurbitarum </b> </i>
