About spirals and pores: Xylariaceae with remarkable germ loci.

ABSTRACT: Based on phylogenetic analyses of a multi-gene matrix of nuITS-LSU rDNA, RPB2 and TUB2 sequences and morphology, xylariaceous species with uni- to pauciperitheciate stromata and ascospores having a spirally coiling (helicoid) germ slit are revised and reclassified, including detailed descriptions and illustrations. The genus Helicogermslita is redefined and restricted to seven species with massive, erumpent, clypeus-like carbonaceous stromata, and Rosellinia somala is combined in Helicogermslita. Within the core Xylariaceae, the poorly known Leptomassaria simplex is shown to be closely related to Anthostoma insidiosum, for which the new genus Oligostoma is established, and Anthostoma rhenanum is demonstrated to be synony
