Abstract

In September 2005, a fungus was isolated from fig fruits in Tehran. Colony on MEA (Malt Extract Agar) attained a diameter of 90 mm and a height of 6 mm after 48 h at 24oC, white at first, then covered with black sporangia, especially around the margin at maturity. Sporangiophores, light brown, encrusted with crystalloid ornamentation, erect, up to 66 µm in diameter, arising directly from substrate, apex bend when young, upright at maturity, simple, rarely branched, widening towards the apex, each terminating in a sporangium, local swelling, dichotomous branching and sporadic septation were observed (Fig. 1, b, f, g & i). Sporangia more or less globose, multi-spored, 25-275m in diameter, white at first, turning light brown to black at maturity, wall persistent, covered with crystalline spines (Fig. 1, a) and having at maturity a longitudinal suture where it separates into two more or less equal halves to reveal a lighter zone of sporangial contents that later become more liquid and drop-like (Fig. 1, f). Columellae mouse-grey coloured with a truncate base, obpyriform, obovoid, obconical to cylindrical, 13-130µm in diameter at the widest point, smooth-walled, with a slight basal collar (Fig. 1, b, f, g & h). Sporangiospores more or less globose, broadly fusiform or ellipsoid, to ovoid or irregular (5-)7.4-14.8(-20)´ (5-)6-8.3(-9) µm, hyaline smooth-walled filled with granular contents, marked with faint striation, with 2-3(-7) hyaline appendages, arising from the ends of the spore (Fig. 1, e & J). Chlamydospores, light brown, smooth-walled, intercalary, singly, rarely in pairs or more, produced in the mycelium, globose with 11-32(-51)mm in diameter, ovoid, barrel-shaped, cylindrical to irregular in shape and size 15-29´ 10-160mm (Fig. 1, c & h). This fungus is heterothallic. The substrate hyphae produce chlamydospores and sporophores that terminate in sporangia with a large columella and a persistent wall that is covered with calcium oxalate crystals and has a longitudinal suture (Fig. 1, d & h). Optimum temperature for growth is 24-30C, sporulation occurs between 5-35oC, at 37oC grows well with no sporulation, little growth occurs at 40oC and no growth at 42° C. This fungus was identified as Gilbertella persicaria as is described by BENNY, G.L. [1991. Gilbertellaceae, a new family of the Mucorales (Zygomycetes). Mycologia 83(2): 150-157]. A subculture is preserved at the fungus culture collection of the Ministry of Jihad-e Agriculture (Iran) under IRAN 1040C.
