将来自美国东南部的红湾仙粮甲虫Xyleborus glabratus（鞘翅目：象甲科：小蠹亚科）的雌性成虫单独浸渍并在培养基上连续稀释，以分离真菌共生体。共回收到6种拉斐尔属植物：R. lauricola、R. arxii和4个新种：R.苏巴瓦河ellipticospora、R. fusca和R.浅褐色的LSU rDNA序列的系统发育分析将这些mycangial居民和Raffaelea的其他物种，以及与豚草甲虫相关的Ambrosiella的一些物种，放入Ophiostoma内的单系，无性分支。Raffaelea中的一些Ambrosiella物种和Dryadomyces amasae的新组合。Ambrosia甲虫与Ceratocystis亲和共生，包括A. trypopoecomb. nov.，保留在Ambrosiella中，但Ambrosiella与小蠹相关的物种被转移到无性型属Hyalorhinocladiella中，称为H. ips，H. macrospora和H. tingens。
Female adults of the redbay ambrosia beetle, Xyleborus glabratus (Coleoptera: Curculionidae: Scolytinae), from the southeastern USA were individually macerated and serially diluted onto culture media for isolation of fungal symbionts. Six Raffaelea species were recovered: R. lauricola, R. arxii, and four new species: R. subalba, R. ellipticospora, R. fusca and R. subfusca. Phylogenetic analyses of LSU rDNA sequences placed these mycangial inhabitants and other species of Raffaelea, as well as some species of Ambrosiella associated with ambrosia beetles, into a monophyletic, asexual clade within Ophiostoma. New combinations in Raffaelea are made for some Ambrosiella species and Dryadomyces amasae. Ambrosia beetle symbionts with Ceratocystis affinities, including A. trypodendri comb. nov., are retained in Ambrosiella, but Ambrosiella species associated with bark beetles are transferred to the anamorph genus Hyalorhinocladiella as H. ips, H. macrospora, and H. tingens.
