Harringtonia chlamydospora

Ciri dan struktur

Diagnosis. Fungus associated with Euplatypus longius mycangium, inhabiting Zanthoxylum sp. (Rutaceae), exhibiting typical septate chlamydospores of 8–21 × 5–7 µm. Fungus producing typical terminal chlamydospore in culture. Description. Colonies initially cream, turning brown with age; reverse light orange on PDA. Fungi rapidly occupying the entire plate. Sexual morph was not observed. Asexual morph was composed of cylindrical, hyaline, regularly septate hyphae, ranging from 2–4 µm thick. Three types of conidiation were observed. The first type is sessile, micronematous, laterally forming globose to hemispherical conidia, sometimes leaving a scar after conidium release, formed solitarily and directly on the vegetative hyphae, 5–6.5 × 3.5–5 µm (Figure 2 J–L). The second type are terminally formed chlamydospores, hyaline, cylindrical, with 0–2 septa, developing a slightly verrucose wall with age (Figure 2 H), 8–21 × 5–7 µm (Figure 2 F–I,M). The third type formed on hyaline phialides, produced terminally or laterally on the main hypha, erect, occasionally irregular, cylindrical, sometimes tapering slightly towards the apex, (15–) 21 (–30) × 2.5 µm (Figure 2 C–E). Conidia hyaline, produced singly, aseptate, globose to elongate, sometimes curved, smooth-walled, commonly exhibiting germ tubes, (3.5–) 6 (–7) × 2.5–3 (–4) µm (Figure 2 S,T).
