A new Chinese record, Anthracoidea heterospora (B. Lindeb.) Kukkonen (1963) on Carex
ensifolia Turcz. ex Ledeb. (Cyperaceae, subgen. Eucarex, section Phacocystis), was collected from
Xinjiang Uygur Autonomous Region of China in 1975. So far, five species of Anthracoidea have been
recognized on section Phacocystis. They are Anthracoidea liroi (Lehtola) Nannf. & B. Lindeb. (1965),
A. heterospora, A. echinospora (Lehtola) Kukkonen (1963), A. variabilis (S. Ito) Kakish. (1982) and A.
bigelowii Nannf. & B. Lindeb (1965). A. heterospora differs from A. liroi, A. variabilis, and A.
bigelowii mainly by its small ustilospores, and from A. echinospora by finely and densely verruculose
ustilospores.
