Collections of a species referred to Sarcosomataceae (Pezizomycetes) from eastern North America were studied both morphologically and using nuc rDNA internal transcribed spacer (ITS) region (ITS1-5.8S-ITS2 = ITS) and approximately 800 bp from the 5' region of the nuc 28S rDNA (28S) to construct a phylogeny. The analyses indicate that these collections are Donadinia seaveri, a species previously known only from Bermuda. Because the associated tree, Juniperus bermudiana, has declined as a result of insect attack, it was thought that D. seaveri might be extinct. This work indicates that it is not extinct but is present in eastern North America. The species is described, new distributional records are given, and its association with the genus Juniperus is discussed.
对来自北美东部的被称为肉杯菌科（盘菌纲）的一个物种的样本进行了形态学研究，并使用核糖体DNA内部转录间隔区（ITS）区域（ITS1 - 5.8S - ITS2 = ITS）以及核糖体28S rDNA（28S）5'区域的约800个碱基对来构建系统发育树。分析表明这些样本是西弗肉杯菌（Donadinia seaveri），该物种此前仅在百慕大被发现过。由于其相关的树木，即百慕大刺柏（Juniperus bermudiana）因昆虫侵袭而数量减少，人们曾认为西弗肉杯菌可能已经灭绝。这项研究表明它并未灭绝，而是存在于北美东部。对该物种进行了描述，给出了新的分布记录，并讨论了它与刺柏属的关联。
