Euphorbia ingens trees have been dying in large numbers in the Limpopo Province of South Africa for approximately 15 years. The ambrosia beetle Cyrtogenius africus is often found infesting diseased and dying trees. The aim of this study was to identify the ophiostomatoid fungi occurring in the galleries of C. africus. Logs infested with this beetle were collected from the KwaZulu-Natal, Limpopo, Mpumalanga, and North West Provinces of South Africa. Fungi belonging to the Ophiostomatales were identified based on morphology and comparison of sequence data for the β-tubulin, ITS1-5.8S-ITS2 and LSU gene regions. A novel species of Ophiostoma and a novel genus in the Ophiostomatales were identified. Inoculation studies with these fungi produced lesions in the branches of healthy E. ingens trees.
在南非林波波省，大戟树大量死亡已有约15年时间。非洲长小蠹这种粉蠹虫经常在患病和濒死的树木上被发现。本研究的目的是鉴定在非洲长小蠹虫道中出现的长喙壳类真菌。从南非夸祖鲁-纳塔尔省、林波波省、姆普马兰加省和西北省收集了被这种甲虫侵染的原木。基于形态学以及β-微管蛋白、ITS1-5.8S-ITS2和LSU基因区域的序列数据比较，鉴定了属于长喙壳目的真菌。鉴定出了一种新的长喙壳属物种和长喙壳目中的一个新属。用这些真菌进行的接种研究在健康的大戟树树枝上产生了病变。
