Zhuang, Wen Ying. The genus Sowerbyella (Pezizales) in China by Wen-Ying Zhuang. Mycotaxon 109: 233–237. 2009.

ABSTRACT:  Studies on collections of Sowerbyella resulted in recognition of four species of the genus in China. A new species, S. laevispora, on mossy soil in Picea forest from Qinghai Province in northwestern China is described and illustrated. It is similar to S. rhenana in apothecial shape and anatomic structure, and distinct from that fungus in wider and shorter ascospores and shorter asci, and from all known species of the genus by its smooth-walled ascospores.
