 Description: Spider host covered by white mycelial mat. Synnemata in groups of 5 or 6, arising directly from the dorsal side of the host, slender, cylindrical, attenuated, yellowish grey (4B2), 4-5 mm long, 96-184 μm wide, composed of parallel, densely compact hyphae. Hyphae of synnemata hyaline, verrucose, 3.2-6.1 μm wide. Conidiophores hyaline, septate, arising from arches in hyphae of the aerial mycelium or from synnemata, scattered or densely compact, 112-244 μm long, 6.4-13.5 μm wide, distinctly roughened along the length, narrowing abruptly to a slender apex, 2.4-4.0 μm diam. And terminating in a swollen vesicle. Conidial head 40-52 μm diam. Vesicle ellipsoidal, subglobose to globose, smooth-walled, occasionally slightly verrucose, hyaline, 7.1-9.9 × 5.6-7.9 μm. Phialides broadly cylindrical to ellipsoidal, smooth-walled, rarely roughened, with a short neck, often apically thickened, hyaline, 6.4-9.5 × 2.8-4.2 μm, in a whorl of 3-12, borne on metulae. Metulae broadly ellipsoidal, obovoidal, hyaline, smooth-walled, occasionally 5.6-9.1 ×4.8-7.0 μm. Conidia fusiform, occasionally apiculate, hyaline, smooth-walled, in short chains, 4.0-6.8 × 1.6-2.2 μm. Conidiophores of Granulomanus synanamorph present, well differentiated, roughened to distinctly verrucose, particularly around the base of the synnemata. Conidiogenous cells of Granulomanus synanamorph holoblastic, cylindrical, clavate, flask-shaped, to irregularly shaped, mostly verrucose, rarely smooth, with one to three conspicuous denticles, 6.8-11.9 × 3.2-4.0 μm, bearing solitary, long, filiform conidia. Conidia smooth-walled, hyaline, 11.1-17.5 × 1.0-1.6 μm. Teleomorph not observed.
