Abstract
A chemotaxonomic evaluation using hplc profiling was undertaken to resolve the infragenericand intergeneric affinities of over 150 strains of Xylariaceae. Daldinia placentiformis,Hypoxylon nicaraguense, H. polyporus, and Phylacia sagrana were found to contain 8-methoxy-1-naphthol, which is apparently absent in Annulohypoxylon, Hypoxylon, andrelated genera with bipartite stromata. D. placentiformis and other species of Daldinia andEntonaema produced this naphthol, 5-hydroxy-2-methylchromone, isosclerone derivatives,and ‘AB-5046’ phytotoxins. Phylacia sagrana differed from most Daldinia spp., except forD. caldariorum, by producing eutypine derivatives in addition to the above compounds.Indolylquinones were observed in H. nicaraguense and H. polyporus. Isosclerones were alsoidentified in the A. multiforme complex, but Hypoxylon and other Annulohypoxylon and mostHypoxylon spp. studied Annulohypoxylon spp. contained 5-methylmellein as the major metaboliteof their cultures. Based on the occurrence of the abovemetabolites, further mellein-typedihydroisocoumarins, teleomorphic and anamorphic Xylariaceae with Nodulisporium-like anamorphs(‘Hypoxyloideae’) were divided into various chemotypes. A comparison of their 5.8S/ITS nuc-rDNA sequences agreed in some important aspects with the above results: H. nicaraguenseand H. polyporus appeared basal to a clade comprising Daldinia, Entonaema, andPh. sagrana. The latter species appeared allied to D. caldariorum, but was distantly related toPyrenomyxa morganii and Hypoxylon s. str.
