Basionym: Cordyceps pseudolloydii Evans &Samson, Trans. Brit. Mycol. Soc. 82: 133 (1984)

Specimens were found on the underside of leaves of forest plants. Stroma arising from between the head and thorax of adult worker ants (Hymenoptera: Dolichoderinae), pale cream-yellow to cream-yellow, 0.3-1 x 0.5-1 mm, single (rarely double). Fertile head terminal, concolorous with clava, hemispherical,slightly flattened, 1.5-2.5 mm diam., ridged and furrowed. Perithecia semi-erumpent, flask-shaped, 350-550 x 130-200 μm. Asci cylindrical, 250-400 x 5-8 μm, apex thickened. Ascospores filiform, breaking into 64 part-spores, 230-370 x 1.5-2.5 μm. Part-spores, ellipsoidal with truncate, frilled ends, 4-10 x 1.5-2.5. μm, hyaline, smooth walled. In culture the colonies on PDA are slow-growing, attaining a diam. of 5-10 mm in 1 mo at 25°C. Ophiocordyceps pseudolloydii has been found throughout Thailand from Doi Inthanon National Park in the North to Hala Bala National Park on the Malay border.
