Ascocarps in vertical section intraepidermal, upper wall 30-40 µm wide, uniform in width across ascocarp. Lining inner side of upper wall near ascocarp opening is a 20-25 µm wide layer of hyaline, 1.5-2 µm diam., cylindrical cells. In older ascomata the upper edge of this layer is dark brown. Lower wall 8-10 µm wide, of slightly thick-walled, brown to pale brown cells.

Paraphyses 1.5-2 µm diam., apex with irregular, short branches and with irregular swellings, extending 10-15 µm beyond asci. Asci 135-195 x 8.5-11 µm, cylindric to subclavate, tapering to small, rounded apex, wall not thickened at apex, 8-spored. Ascospores 70-140 x 1.5-2 µm, tapering slightly to both ends, often bending at right angles when released, 0-1 septate.

Pycnidia in vertical section 70 µm high, upper wall 7-10 µm wide, black, lacking any cellular structure. Lower wall up to 25 µm wide, of dark brown, thick-walled, 3-6 µm diam. cells. Beneath central ostiole a column of hyaline, cylindric, 1.5-2 µm diam. cells extending to top of pycnidium. Conidiogenous cells lining lower wall, solitary, 8-11 x 1.5-2 µm, hyaline, flask-shaped, sympodial. Conidia cylindric, 0 septate, hyaline, 3-4.5 x 0.8-1 µm.

NOTES: L. tindalii is similar to L. nigrofactum and L. brunneolum, two other Dracophyllum-inhabiting species. See notes under L. brunneolum.
