葡萄座腔菌科（Botryosphaeriaceae）包括重要的植物相关病原体、内生菌和腐生菌，具有广泛的地理和宿主分布。本文报道了采自中国西北部宁夏地区的两种与火炬树枯梢病和溃疡病有关的暗孢子球腔菌科植物。形态学和多基因分析（ITS，LSU和EF-1α）清楚地将该分支区分为属中的一个独特种。本文介绍了Rhois这一新种。该种的特征是其球形，单室的子实体和小，棕色，1隔的分生孢子。它可以根据寄主组合和分生孢子大小和颜色与相似种P. cercidis、P. cupressi、P. mamane和P. quercicola区分。
The family Botryosphaeriaceae encompasses important plant-associated pathogens, endophytes and saprobes with a wide geographical and host distribution. Two dark-spored botryosphaeriaceous taxa associated with Rhus typhina dieback and canker disease were collected from Ningxia Province, in northwestern China. Morphology and multigene analysis (ITS, LSU and EF-1α) clearly distinguished this clade as a distinct species in the genus. Phaeobotryon rhois is introduced and illustrated as a new species in this paper. The species is characterized by its globose, unilocular fruiting bodies and small, brown, 1-septate conidia. It can be distinguished from the similar species P. cercidis , P. cupressi , P. mamane and P. quercicola based on host association and conidial size and colour.
