(Rhamnaceae) in 2012. <...> Conidiophores sparingly branched, hyaline, bearing one or more phialides, 100—140 7 2.5—3.5 µm. <...> Conidia straight or slightly curved, slimy, solitary, hyaline, cylindrical narrowed at the base, with 3—4(5) distinct and 1—2 indis A new species, Heliscus atilae from Turkey 27 General view on conidia of Heliscus atilae: a—4-septate conidium with one septated arm, b—conidium with two aseptate arms, c — 3-septate conidium with rudimentary arms, d — 3(4)-septate conidium with rudimentary arms, e — 4-septate conidium with developed arms, f — 4-septate conidium with unseptate arms, g — conidium with rudimentary septa on the arms, h — 4-septate conidium with rudimentary arms, i—4-septate conidium <...>
