| Description： |
Colonies slow-growing on CMA (corn meal agar), obtaining a diam of 1-1.5 cm in 14-20 d at 25°C. Colonies effuse, orange white to orange, reverse in shades of pale orange white. Mycelium mostly immersed, branched, septate 1.6-6 μm wide. Conidiophores micronematous, mononematous, straight or flexuous, smooth, hyaline. Conidiogenous cells pleurogenous or acrogenous, determinate or sympodial, smooth, hyaline.Conidia Y-shaped, smooth, hyaline, pale brown in mass, main axis clavate, 1-6 but mostly 2-3 septate, 15-20 μm long, 3.8-6.3 μm wide, usually with 2, but rarely 3-4 divergent, 1-5 (mostly 2-3) septate arms, arms tapered and rounded at the ends, 9.6-25 μm long, 4.6-6.3 μm wide, slightly constricted at the septa. | |||

| Note： |
Species can be distinguished by the parameter of length and width of the main axis and arms, or the shape of the conidia. For instance, in T. robustum the arms and main axis of a conidium are markedly shorter and wider giving them a stout appearance, which differs from other described Trinacrium species (Drechsler, 1938; Matsushima, 1975, 1980, 1987; Saccardo, 1886). | |||
