Based on phylogenetic analyses of a multi-gene matrix nuITS-LSUrDNA, RPB2 and TUB2 sequences morphology, xylariaceous species with uni- to pauciperitheciate stromata ascospores having spirally coiling (helicoid) germ slit are revised reclassified, including detailed descriptions illustrations. The genus Helicogermslita is redefined restricted seven massive, erumpent, clypeus-like carbonaceous stromata, Rosellinia somala combined in .
