 Description: Spider host completely covered by a mat of mycelium, white, yellowish white (4A2), pale, pastel to light or greyish yellow (2A3-4, 3A4-6, 3B5-6), occasionally orange white, pale to light orange (5A2-4). Synnemata solitary to numerous, arising from all parts of the host, cylindric, attenuated, 4-7 mm long, 120-144 μm wide, consisting of parallel multiseptate longitudinal hyphae. Hyphae hyaline, verrcuose, 3.2-5.5 μm wide. Conidiophores greenish white to pale green (30A2-3), arising from the mycelium covering the host or from the syn-nemata, 110-640 × 7.9-10.3 μm, septa conspicuous, thickened and often darkly pigemented, distinctly roughened and warty at the basal 3-5 cells, narrowing abruptly to a slender apex, 2.8-4.0 μm, and terminating in a swollen vesicle. Conidial head 40-48 μm diam. Vesicle mostly ellipsoidal to globose, 8.7-10.3 × 7.9-8.7 μm. Phialides cylindrical to narrowly clavate, with a short neck, often apically thickened, hyaline, 6.4-10.3 × 2.0-2.4 μm, numer-ous, up to 10, borne on metulae. Metulae broadly obovoid, hyaline, 7.9-9.9 × 5.2-6.4 μm, numerous, up to 20, borne on vesicle. Conidia hyaline, ellipsoidal, sometimes fusoid, smooth-walled, single or catenulate, 4.0-6.0 × 2.0-2.4 μm. Teleomorph and Granulomanus synanamorph not observed.
