 Description: Colonies grew slowly on oat meal agar (OMA), 10 mm in diameter in 14 days at 25°, ve-lutinous to plane, greyish brown, margin irregular; reverse greyish brown to dark brown. Mycelium partly superficial, partly immersed composed of branched, septate, smooth, pale greyish brown to greyish brown, 1.6-6.4 μm wide, often catenulate hyphae. Conidiophores micronematous, mononematous; conidiogenous cells intercalary, terminal, cylindrical, doli-iform, clavate, monoblastic or polyblastic, with denticle scattered. Conidia lateral or termi-nal, mostly k-, rarely y-shaped, septate, smooth, hyaline to subhyaline or pale brown in mass; conidia composed of a longly main axis and two (rarely one) branched arm; main axis often truncate at the base, tapering and rounded at the apex, up to 21 septate, 61.8-164.6 μm long, 1.6-2.4 μm wide, occasionally slightly constricted at the septa; branches tapering, often lat-eral arising from the second and fourth cells (occasionally the third and fifth cells) of main axis, up to 5-septate, 12.0-54.0 μm long, 1.4-2.2 μm wide.

 Note: The conidiogenesis and conidial morphology of L. lushanense are close to L. wauense Matsushima. However, L. lushanense has larger conidia, longer main axis with more septa and two lateral branches arising from different locations. L. wauense also has smaller conidia and only one branched arm arising from the second cell of main axis. Both T. angulatum and L. lushanense also have closely similar conidial morphology, but L. lushanense has denticulate, porliferation-sympodial conidiogenous cells, rostrate basal cell conidia and longer branches.
