 Scientific Name: Leptoxyphium sp.

Leptoxyphium sp. Speg., Physis, Buenos Aires 4: 294 1918.

 Description: Colonies growing slowly on Potato Dextrose Agar at 25℃, velvety, slimy, with cream distinct conidia droplet on surface, grayish-green to greenish-olivaceous, reverse black. Mycelium partly immersed, composed of branched, thick-walled, finely rough, pale brown to grayish- brown, procumbent hyphae, 5 - 7 μm wide. Synnemata erect, solely, dark brown or brown, thick-walled, swollen at the base, bearing hyaline penicillate phialides at the tip, cupulate, often synnemata proliferating while aged, 190 - 370 × 15 – 18 μm. Conidia abundant, hyaline to light brown, ellipsoid to claviform, smooth, 0 - 2-septate, mostly in 0 - 1-septate, slightly constricted at septa, conidia non-septate 5.3 - 9 × 3.1 – 4.2 μm, 1-septate 10 - 13.3 × 4.1 - 5.5 μm, 2-septate 20 - 21 × 4.9 - 6 μm.

 Note: Superficially, the Leptoxyphium sp. on a decaying leaf isolated from Taiwan was somewhat reminiscent of Graphium. However, the Leptoxyphium sp. in the initial developing stage the sporulating apparatus was membranceous, cupulate, later expanded and membrane ruptured. The Leptoxyphium sp. was characterized by composing of distinct swollen basal cells and by proliferating synnemata, particularly when aged, which greatly contrast to The Graphium genus.
