''Hemileia vastatrix'' is a fungus of the order Pucciniales (previously also known as Uredinales) that causes coffee leaf rust (CLR), a disease that is devastating to susceptible coffee plantations. Coffee serves as the obligate host of coffee rust, that is, the rust must have access to and come into physical contact with coffee (''Coffea sp.'') in order to survive. ==Appearance== The mycelium with uredinia looks yellow-orange and powdery, and appears on the underside of leaves as points ~0.1 mm in diameter. Young lesions appear as chlorotic or pale yellow spots some millimetres in diameter, the older being a few centimetres in diameter. Hyphae are club-shaped with tips bearing numerous pedicels on which clusters of urediniospores are produced. Telia are pale yellowish, teliospores often produced in uredinia; teliospores more or less spherical to limoniform, 26–40 × 20–30 µm in diameter, wall hyaline to yellowish, smooth, 1 µm thick, thicker at the apex, pedicel hyaline. Urediniospores are more or less reniform, 26–40 × 18-28 µm, with hyaline to pale yellowish wall, 1–2 µm thick, strongly warted on the convex side, smooth on the straight or concave side, warts frequently longer (3–7 µm) on spore edges. Spermogonia and aecia are unknown. 抄文引用元・出典: フリー百科事典『 '''''Hemileia vastatrix''''' is a fungus of the order Pucciniales (previously also known as Uredinales) that causes coffee leaf rust (CLR), a disease that is devastating to susceptible coffee plantations.

Hyphae are club-shaped with tips bearing numerous pedicels on which clusters of urediniospores are produced.Telia are pale yellowish, teliospores often produced in uredinia; teliospores more or less spherical to limoniform, 26–40 × 20–30 µm in diameter, wall hyaline to yellowish, smooth, 1 µm thick, thicker at the apex, pedicel hyaline.Urediniospores are more or less reniform, 26–40 × 18-28 µm, with hyaline to pale yellowish wall, 1–2 µm thick, strongly warted on the convex side, smooth on the straight or concave side, warts frequently longer (3–7 µm) on spore edges.Spermogonia and aecia are unknown.」の詳細全文を読む ' is a fungus of the order Pucciniales (previously also known as Uredinales) that causes coffee leaf rust (CLR), a disease that is devastating to susceptible coffee plantations.
