Lecanicillium subprimulinum S.K. Huang & K.D. Hyde , sp. nov. Fig. 2

Index Fungorum number: IF553982; Facesoffungi number: FoF03781

Etymology:— The name subprimulinum refers to the yellow pigment (in Latin: primulinum =primrose-yellow) on PDA medium.

Associated with ophioceras-like taxon on dead submerged wood. Sexual morph Undetermined. Asexual morph:

Mycelium 1–3 μm diam., partly superficial, composed of septate, branched, hyaline hyphae. Conidiophores 19–32 × 1.5–3.5 μm (x = 24 × 2.5 μm, n = 20), usually arising from hyaline hyphae, septate, rarely uni-septate, hyaline,

tapering towards apex, discrete, solitary or up to 2–3 conidiogenous cells per node, often with secondarily produced phialides. Conidiogenous cells 15–25 × 1–3 μm (x = 20 × 1.5 μm, n = 30), monophialidic, elongate, fusiform, wide at base, narrowed at apex, with a small collarette, smooth, hyaline. Conidia 4–15 × 2–6 μm (x = 10 × 4 μm, n =

30), hyaline, ovoid to ellipsoidal, elongated, straight or slightly curved, aseptate, smooth, developing in basipetal succession, accumulated in a slimy mass at the apex of phialides.

Culture characteristics:—The conidia germinated on PDA after 2 days at 23 °C and sporulating after 35 days and colony reaching 2 cm diam.; colony circular, umbonate, with filiform margin, with radiating surface texture and creamy from above, with clear radial crack and primrose-yellow from reverse.

Material examined: — CHINA, Yunnan Province, Baoshan, a stream along the roadside; on dead wood, 21
