Gibellula clavulifera var major Tzean et al., Mycologia 89: 311. 1997.

 Description: Mycelium covering the host, white to yellowish white (4A2). Synnemata solitary, white to yellowish white (4A2), arising from the posterior of the host abdomen, slender, cylindrical, sometimes curved towards the posterior of the host abdomen, slender, cylindrical, some-times curved towards the end, 10-15 mm long, 400-500 μm wide, consisting of a compact bundle of parallel hyphae. Conidiophores arising directly from aerial mycelium, or apically or laterally from synnemata, hyaline, mostly biverticillate or terverticillate, occasionally monoverticillate, stout, smooth or slightly roughened, up to 140 μm long, 4.8-7.1 μm wide. Vesicles absent or hardly developed. Rami cylindrical, sometimes septate, 25.0-34.0 × 4.8-6.0 μm. Ramuli cylindrical, 15.9-20.6 × 4.4-6.4 μm, bearing 3 to 10 metulae. Metulae clavate tocylindrical, 12.7-19.8 × 4.0-5.6 μm, bearing 2 to 8 phialides. Phialides ampulli-form to cylindrical, 12.7-19.8 × 3.6-4.8(-5.3) μm, apex slightly thickened, neck absent or indistinct. Conidia in chains, hyaline, slightly thick-walled, 7.1-12.0(-13.9) × 2.4-4.0(-5.6) μm, one-celled, broadly fusiform to fusiform, either apiculate or with slightly rounded ends. Granulomanus synanamorph present. Conidiophores arising from the stipe of Gibellula sy-nanamorph, hyaline, smooth or inconspicuously roughened, bearing apically whorled polyblastic conidiogenous cells. Conidiogenous cells cylindrical to flask-shaped, with one to two conspicuous denticles, 9.5-14.6 × 2.7-4.4 μm, each denticle giving rise to a solitary co-nidium. Conidia filiform to bacilliform, 15.9-26.2(-34.1) × 1.3-2.4 μm, sometimes slightly swollen and apiculate at one end, one-celled, smooth-walled, hyaline. Teleomorph not ob-served.
