Etymology:– wuyiense , L. referring to the type location.
Type:– CHINA. Fujian Province, Wuyi Mountain National Nature Reserve, Tongmugou, on a dead branch of bamboo, 12 July 2015, coll. G.Z. Zhao, HMAS 247191 (Holotype), ex-Holotype culture CGMCC 3.18703 (= ZY 16

Differs from other sporodochial species in Dictyosporium by its two types of conidia, sometimes with variable hyaline apical vesical appendages.
Colonies on natural substrate in the form of sporodochia, black, scattered, punctiform, granular. Mycelium mostly immersed in substrate, composed of branched, septate, smooth, subhyaline hyphae, becoming yellow at maturity. Conidiophores micronematous or semi-macronematous mononematous, fasciculate, simple or sparsely branched, septate, hyaline to subhyaline, smooth. Conidiogenous cells integrated, terminal, determinate, cylindrical or slightly vesiculate. Conidia with two morphologies, solitary, cheiroid, complanate, smooth, yellow, composed of five rows of cells compacted together (sometimes four and six rows), some with one or two variable apical swollen vesical appendages. Type 1 ( Fig. 2 C, E‒H View FIGURE 2 ) conidia longer, 42–70 × 20–33 μm, the three central rows are protruding with swollen apical cells, some of which have 1‒2 globose hyaline mucous apical vesical appendages ( Fig. 2 G, H View FIGURE 2 ). Type 2 ( Fig.2 D, I, J View FIGURE 2 ) wider conidia, 33–52 × 27–43 μm, fan, rows of apical cells approximately the same length. The apical cells of the outer rows are sometimes incurved.
Colonies on PDA plates grew slowly, reaching 1 cm diameter in 1 month at 28°C, white at first, becoming orange. Sporulating regions scattered over the medium in patches. Conidia are more variable in morphology and most have 1–3 swollen vesical appendages unlike those on natural substrate ( Fig. 3 View FIGURE 3 ).
