INTRODUCTION
Leveillula taurica Lev. Belong to Erysiphaceae (Erysiphales,
Ascomycota) that causing powdery mildew on over from 50
plant families(1).
MATERIALS AND METHODS
During the summer 2007, typical symptoms of powdery mildew
were observed in several fig fields assessed in Kereman Province,
Iran. Samples were stained with Lactofushin(3) and
morphological characteristics of fungus investigated by Olympus
microscope (Modle: BH2) and drawn by drawing tube connected
on microscope.
RESULTS AND DISCUSSION
Morphological characters of this fungus on ficus carica is as
follow:
Diseased leaves displayed typical powdery mildew signs
consisting of whitish masses of conidia and conidiophores.
Mycelial growth was thick, forming irregulare white patches,
sometimes effused to cover the whole leave surface and usually
not present appressoria. Conidiofores erect, foot cells cylindric,
40–126 (‐148)
×
4/5–7/8µ
m usually followed by (1‐) 2–3 (‐4)shorter and different length cells. Conidia formed singly, primery
conidia lancaeolate, 31–67 (80)

were gregarious to scattered and measured 145–250

m indiameter. Appendages were myceliod, arising from the lower
half of ascomata, brown, paler upward. Asci 20–30 (‐45) in each
cleistothecia, clvate, stalked, 77–120 (‐135)

m.Ascospores (1‐) 2 (‐4) in each ascus, ellipsoid‐ovoid shaped, (20‐)

m (fig 2).On the basis of morphological characters of the anamorph and
telemorph, this fungus was identified as Leveillula taurica (1).
