    Specimens were found on the underside of leaves of forest plants. Hosts are cockroach nymphs (Blattaria). Stromata up to 15 mm long x 200-350 μm wide, cylindrical, very pale pink. The fertile head was distinctly sub-terminal with the anamorph state at the apex. Perithecia immersed obliquely, ostioles projecting, elongate flask-shaped, up to 150-180 μm long x 100-130 μm wide. Asci cylindric, hyaline, capitate, 8-spored, up to 90 μm long, 6-8 μm wide. Ascus cap rounded, 8-9 μm long x 6.9-9.5 μm wide. Ascospores whole, cylindric, 40-60 μm long, 5-6 μm wide. On PDA the discharged ascospores germinate to produce microconidia but develop no further. Recently, a method for isolating Ophiocordyceps unilateralis has proved successful with slow-growing isolates of blastospores in Grace’s insect tissue culture medium, giving rise to slow-growing cultures on PDA (Wongsa et al. 2005). Ophiocordyceps blattae is known only from central and northern Thailand: from Nam Nao National Park, Petchabun, Khao Yai National Park, Nakhon Ratchasima, Khlong Lan National Park, Kamphaengpet, Phu Luang Wildlife Sanctuary, Loei and Huai Nam Dang National Park, Chiang Mai. It is especially common at the end of the rainy season.
