摘要：

Spencermartinsia is a genus in Botryosphaeriaceae characterized by brown, 1-septate ascospores with an apiculus at either end, and usually found on woody hosts. Conidia are twocelled and become brown and 1-septate prior to dehiscence from conidiogenous cells. Based on morphological characteristics and phylogeny of DNA sequences of the internal transcribed spacer (ITS) region and part of the translation elongation factor 1-alpha (tef1-alpha) gene, two new species, namely Spencermartinsia alpina and S. yunnana are described from Yunnan province in China.
