Description: | Colonies growing fast on Potato Dextrose Agar at 25℃, floccose, villose, effuse, with finely slimly granular, light yellow or pale yellowish-white to light pale orange, reverse yellowish- white. Mycelium partly immersed, composed of branched, smooth, thin-walled, septate, hyaline hyphae, 2 - 3 μm in wide. Conidiophores branched, mostly biverticillate, rarely monoverticillate, hyaline, smooth, , bearing phialides in whorls of 2 - 5, 24 - 86 × 3 - 4.9 μm. Phialides cylindrical, acerose, smooth, hyaline, 21 - 38 × 2.5 - 3 μm. Conidia ellipsoid, slightly curved, unicelled, smooth, hyaline, 5.5 - 6.6 × 3 - 4.5 μm, forming white or pale orange false head. | |||

Note: | The biverticillate or rarely monoverticillate conidiophores of C. zelandiae-novae is more and less similar to Glicocladium. However, the latter in which the conidiophores are mostly more complicate, bearing rami, ramulae and terminal phialides. The thoroughly phylogenetic study of Bionectriaceae and their anamorphic Clonostachys clearly revealed their relatedness among allied species. However, blasting the amplified and sequenced ITS rDNA from our isolate showed a perfect match with the already described C. zelandiae-novae, therefore is considered to be conspecific. Actually, for accurate identification, except morphological traits, molecular marker is also helpful for judgment. | |||
