 Description: Colonies growing fast on Potato Dextrose Agar at 25℃, villose, effuse, slimy in age, white to cream white or light yellowish, reverse white to light yellowish. Mycelium partly immersed, composed of branched, septate, smooth, often with intercalary swollen chlamydospore-like cells, hyaline, 2 - 5 μm wide. Conidiophores micronematous. Arthrospores forms by random articulation of surfacial, branched or non-branched vegetable mycelium, rounded rectangular or ellipsoid, hyaline, smooth, 0-1-septate, 5 - 9 × 2.1 - 3 μm.

 Note: Morphologically, the arthrosporogenesis features of our isolate comply with the circumscription of the Arthrographis genus, hence, represents a member of this genus. However, our Arthrographis isolate contrasts with several closely related Arthrographis species, i.e. A. alba, A. cuboidea, and A. longicola not only in the size of arthroconidia or chlamydoapores- like swollen cells, but also shows difference in identify index of ITS1-5.8S-ITS2 rDNA sequence.(usually less than 96%). Usually the spore size of our isolate is larger than the above-mentioned three species, also 1-2-septate.
