　Description： Colonies on corn meal agar thinly effuse; center grey white to dark brown; margin hyaline. Mycelium septate, branched, partly superficial but mostly submerged. Conidiogenous cells hyaline, smooth, borne directly on the mycelium, solitary or agglomerate to caespitose, forming sporodochia-like structures, flask-shaped, cylindrical, doliiform, macronematous, holoblastic, monoblastic, determinate, 2.8-6.4 × 2.7-3.9 μm. Conidia acrogenous, solitary, dry, of five different forms: 1) cylindrical, straight or slightly curved, 13.7-24 × 4-8 μm, 1-2-septate; septa covered with dark 2 μm bands; wall smooth; tip and central cells brown, basal cell hyaline or pale brown; tip rounded and base rounded or truncate, 1.3-3.1 μm wide, rarely with inconspicuous pore; 2) broadly clavate, 11.5-15.3 × 6.3-8 μm, with one transverse septum near the base, covered with a dark 1.8-2 μm band; wall smooth; tip cell brown, basal cell hyaline or pale brown, with truncate base 2-4 μm wide; 3) obclavate, 4-6-septate, 15-26 × 6-7 μm; end cells hyaline or pale brown, acicular, basal cells subhyaline to pale brown, truncate, central cells pale brown to brown, often with 0.8-1.6 μm dark bands at the septa; 4) allantoid or reniform, hyaline or pale brown, 1-septate, smooth, thin-walled, 8-16 × 3-5 μm; and 5) obovate, pale brown, unicellular, smooth, 5.9-9.8 × 4.3-5.6 μm; hilum inconspicuous; base truncate.

　Note： Gross morphological characteristics of T. diversa are similar to T. heterospora and T. inquinans. Nevertheless, there are several noticeable differences. For instance, T. heterospora did not produce B-type conidia, while T. diversa does so. While A-type conidia produced by T. diversa are characterized by septa covered with 1-2 dark bands, A-type conidia of T. heterospora show a single broader dark band covering the septa. The basal cell is usually brown and rounded in T. heterospora, but conidia of T. diversa possess hyaline or pale brown, truncate or rounded basal cells. The D-type conidia of T. diversa are obclavate, those of T. heterospora are broadly obclavate or ellipsoid. Pronounced differences also exist in shape, size, band position and band number in A-, B-, and E-type conidia in T. diversa and T. inquinans. Additionally, C-type conidia are produced by T. inquinans but not by T. diversa, and E-type conidia are produced by T. diversa but not by T. inquinans.
