Puccinia longicornis: teliospores



No host plant alternation; only uredinia and telia. The uredinia are hypophyllous, yellowish brown; between the spores cinnamon brown, aseptate, distinctly capitate and thin walled paraphyses. Telia are rare, just a few per leaf. Telia only slightly darker than the uredinia.

host plants

Poaceae, narrowly oligophagous

Bambusa; Phyllostachys aurea; Pseudosasa humilis, japonica; Sasa palmata, veitchii; Thamnocalamus tessellatus.
