A new species belonging to the Dothideomycete genus Acanthostigma is described from bark of two Nothofagus species from Argentina. Its identity as a new species is based on both morphology and molecular sequence data. Acanthostigma patagonica differs from other species in the genus by having larger ascomata and setae and wider, asymmetrical ascospores. An amended key to Acanthostigma species is provided along with a discussion of other species previously described from South America.
一个新的物种属于叶点霉属 Acanthostigma 是从阿根廷的两个贝壳杉物种的树皮中描述的。它作为一个新物种的身份是基于形态和分子序列数据。巴塔哥尼亚 Acanthostigma 与属中的其他物种不同，具有较大的子囊壳和刚毛，以及更宽、不对称的子囊孢子。提供了一个修订的 Acanthostigma 种的关键，并讨论了以前从南美洲描述的其他物种。
