Abstract The new genus Burrowsia (Caliciaceae) is proposed to accommodate the new species B. cataractae, which is known from only a single locality in Mpumalanga, South Africa. Burrowsia is characterized by its pigmented, submuriform ascospores and ascus with an apical tube structure, and also by its DNA sequence data that place it outside related buellioid genera. We also describe the new species Scoliciosporum fabisporum, also known from a single locality in Mpumalanga, which differs from all other species of that genus in having distinctive kidney-shaped, 0–1-septate ascospores. It is most closely related to the Northern Hemisphere species S. intrusum, which is here confirmed by molecular data as belonging to this genus in a well-supported Scoliciosporaceae. The potential of the region to yield additional novel lichen taxa is explored.

Burrowsia，一种新的地衣真菌（Caliciaceae）属，以及来自南非普马兰加省的新种 B. cataractae 和 Scoliciosporum fabisporum

摘要 新属 Burrowsia (Caliciaceae) 被提议容纳新物种 B. cataractae，该物种仅在南非普马兰加的一个地方已知。Burrowsia 的特征在于其有色的、亚黏液状子囊孢子和具有顶端管结构的子囊，以及将其置于相关 buellioid 属之外的 DNA 序列数据。我们还描述了新物种 Scoliciosporum fabisporum，也从普马兰加省的一个地方已知，它与该属的所有其他物种的不同之处在于具有独特的肾形 0-1 分隔子囊孢子。它与北半球物种 S. intrusum 的亲缘关系最密切，这里通过分子数据证实，它属于得到充分支持的 Scoliciosporaceae 中的该属。探索了该地区产生更多新地衣类群的潜力。
