Cladosporiosis on tomato (Passalora fulva)

Many leaflets and tomato leaves are covered with more or less chlorotic spots. <i><b>Passalora fulva</b></i> (<i>Mycovellosiella fulva</i> or <i>Fulvia fulva</i>) (cladosporiosis, leaf mold)
Detail on the upper side of the lamina of more or less chlorotic spots caused by <i><b>Passalora fulva</b></i>. (<i>Mycovellosiella fulva</i> or <i>Fulvia fulva</i>) (cladosporiosis, leaf mold)
Diffuse pale green to yellow spots cover the leaf blade of several tomato leaflets. <i><b>Passalora fulva</b></i> (<i>Mycovellosiella fulva</i> or <i>Fulvia fulva</i>) (cladosporiosis, leaf mold)
Some spots present on the leaf blade of this tomato leaflet are yellowish and sometimes partially delimited by the veins; some begin to die. <i><b>Passalora fulva</b></i> (<i>Mycovellosiella fulva</i> or <i>Fulvia fulva</i>) (cladosporiosis, leaf mold)
The diffuse and yellowish spots located under the blade reveal the presence of a superficial olive brown velvety. <i><b>Passalora fulva</b></i> (<i>Mycovellosiella fulva</i> or <i>Fulvia fulva</i>) (cladosporiosis, leaf mold)
Appearance of the spots caused by <i><b>Passalora fulva</b></i> and observed by transparency on the underside of the leaflets. (<i>Mycovellosiella fulva</i> or <i>Fulvia fulva</i>) (cladosporiosis, leaf mold)
Detail of the olive brown mold that has gradually developed on the surface of the leaf blade under this tomato leaflet. <i><b>Passalora fulva</b></i> (<i>Mycovellosiella fulva</i> or <i>Fulvia fulva</i>) (cladosporiosis, leaf mold).
<i><b>Passalora fulva</b></i> sometimes colonizes the sepals of fruits, covering them with its fruiting bodies. (<i>Mycovellosiella fulva</i> or <i>Fulvia fulva</i>) (cladosporiosis, leaf mold)
Detail of the olive brown sporulation gradually formed by <i><b>Passalora fulva</b></i> on this tomato fruit sepal. (<i>Mycovellosiella fulva</i> or <i>Fulvia fulva</i>) (cladosporiosis, leaf mould).
Thanks to a binocular magnifying glass, the many fruiting bodies constituting the velouté can be easily observed. <b> <i> Passalora fulva </i> </b> (cladosporiosis, leaf mold)
Numerous irregular conidia, sometimes septate and brownish, are observed on the lamina. <b><i>Passalora fulva</i></b> (cladosporiosis, leaf mold)
Detail of the most characteristic bicellular conidia of the asexual form of <b><i>Passalora fulva</i></b> (cladosporiose, leaf mold)
