Camposporium fusisporum
Camposporium fusisporum Whitton, McKenzie & K.D. Hyde
Index Fungorum number: IF 489896
Etymology: fusisporum, refers to the fusoid shape of the conidia.
Description from Whitton et al. (2002) observed from Pandanus sp. (mangrove associate):
Colonies on natural substrate effuse, consisting of individual conidiophores scattered over the substrate surface, brown. Mycelium immersed and superficial, superficial hyphae pale brown, septate, cylindrical. Stroma none. Hyphopodia absent. Setae absent. Conidiophores 100–145 μm long, 6.5–10 μm wide at the base, macronematous, mononematous, irregularly cylindrical, strongly flexuous to twisted, erect, brown, sometimes fading slightly towards the apex, smooth, simple or infrequently branching towards the base, thickened walls and septa, 10–15-septate, often slightly constricted at the septa, each cell is connected via a small, circular pore at the centre of each septum, individual cells short, 7–17 μm long. Conidiogenous cells holoblastic, mono- or polyblastic, integrated into the apical region of the conidiophore, denticulate; dentic1es cylindrical, sometimes curved, pale brown, smooth, sometimes remaining attached to the conidia following detachment, acting as a separating cell, ca. 2 μm diam. Conidia 86–115 μm long, 13.5–19 μm wide at widest point, solitary, dry, fusoid, elongate, brown or pale brown, typically the two end cells are slightly paler in pigmentation than the rest of the conidium, smooth, thickened walls and slightly thickened septa, each septum has a single, central, circular pore, 8-11 (typically 9-)-septate, often slightly constricted at the septa, basal cell conical with a truncate and strongly thickened end, apical cell rounded with 2–3, independent, simple, cellular, aseptate, hyaline, smooth, straight, curved or flexuous appendages, 17–40 μm long, 1.5–2.8 μm wide towards the base.
Freshwater distribution: Philippines (Cai et al. 2003)
