Specimens were found on hunting spiders (especially crab spiders, Thomisidae) attached to the underside of living leaves of forest plants. Stroma of white to grayish white mycelia completely covering the thorax and abdomen of the host, sometimes extending to the legs. Synnemata numerous, erect, simple, up to 6 mm high and 50 μm in diam., brown at the sterile base, becoming gray-white with conidia. Phialides one to several on each metula, crowded, smooth-walled, obovoid when immature to ellipsoid, 4-5.5 x 3-3.5 μm, with a long neck, 2.5-3 x 0.5-1 μm. Conidia catenate, one-celled, smooth-walled, hyaline, clavate, 4.5-5.5 x 1-1.5 μm. Isolates on PDA are slow-growing, attaining a diam. of 10-15 mm in 21 d at 22°C with white aerial mycelia. There was no sign of sporulation in culture but it produces a pallid wine-red pigment diffusing into the agar. Akanthomyces koratensis is known only from Khao Yai National Park, Nakhon Ratchasima. This is a very rare species with only solitary specimens being found.
