Description:
<jats:title>Abstract</jats:title><jats:p> <jats:italic>Verticillium balanoides</jats:italic> mycelial growth was stimulated on solid corn meal agar (1.7 %) and in liquid corn meal broth (0.2 %) upon the addition of phospholipids at various concentrations. Sporulation differed with phospholipid products and was highest in pure corn meal. <jats:italic>Drechmeria coniospora</jats:italic> mycelial growth increased upon addition of phospholipids at all concentrations in solid or liquid culture. Sporulation increased at high concentration (1000 ppm) and decreased at low concentration (100 ppm) of phospholipids in the medium. For both fungi, infectivity of conidia produced in liquid culture decreased when compared to conidia from parasitized nematodes. Addition of phospholipids partly restored this effect. <jats:italic>Harposporium anguillulae</jats:italic> mycelial growth and sporulation was not affected by addition of phospholipids to solid or liquid corn meal medium.</jats:p>
