FIGURE 5. Helminthosporium taiwanense (strain NCYU-113RA1-2B1). Scanning electron micrographs. a. Conidiophore producing branched chains of conidia. b. Chain of three conidia attached to a conidiophore. c. Apical region of a conidiophore with developing conidia. The arrow indicates a conidiogenous pore at the conidiophore apex. d. Conidium attached to a conidiophore. The arrow indicates the secession scar (a pore) at the apex of the conidium formed after the disarticulation of a subsequent conidium. e. The arrow indicates a nascent conidium developing from the apex of a conidium that is still attached to the conidiophore. f. Developing conidia attached to a conidiophore. Arrow indicates the branch point where secondary conidia arise from the base of the primary conidia. g. Conidiophore producing conidia both terminally and laterally. h. Apex of a conidiophore showing multiple conidiogenous pores (secession scars). i. Detached conidium. The arrow indicates the unthickened hilum at the base, characteristic of schizolytic secession. Scale bars: a, b, g = 20 µm, c, d, f = 10 µm, e, i = 5 µm, h = 2 µm.
