 Description: Colonies growing slightly fast on Potato Dextrose Agar at 25℃, effuse, pale white or light yellow, sometimes reddish-brown in aged, reverse dark brown or brown. Mycelium partly submerged, partly superficial, composed of branched, septate, smooth, hyaline, thick-walled in older hyphae, sometimes funiculus, 2 – 8 μm wide. Conidoiphores penicillate, erect, hyaline, primiary branches about 13 - 16 × 3 – 4 μm, secondary branches 12.5 - 16(-18) × 3 - 3.5 μm, tertiary branches 12.5 - 13(-18) × 2.9 - 4.1 μm. Phialides doliiform to cymbiform to cylindrical, hyaline, smooth, central phialides often longer than the rest, slightly constricted at base, 14 - 20 × 2.9 - 3(-4) μm. Conidia hyaline, elongate-ellipsoid, smooth, 1-septate, sometimes finely constricted at septa, with round ends, 17.9 - 22.1 × 2.3 - 3 μm, and mostly in 20 μm, aggregate forming slimy, cream white false head.

 Note: Gliocladiopsis tenuis is characterized by triverticillate, penicillate conidiophores, bearing dolliform to cymbiform, smooth.phialides, though occasionally elongate-ellipsoid. G. tenuis resembles to Cylindrocladiella and Cylindrocladium not only in sporulating and conidiogenesis, but also in rDNA (ITS1-5.8S-ITS2) sequence similarity and identity (e value=0, identity 97%) in NCBI GenBank database. However, both Cylindrocladiella and Cylindrocladium always produced apical swollen vesicles on central sterile flag-shaped branches among the whorled conidiogenous cells, but this character is absent in the current G. tenuis isolate.
