A new species of Infundichalara from pine litter
A new species of Infundichalara (anamorphic Helotiales), a hitherto monotypic genus, is described from pine needle litter. Infundichalara minuta sp. nov. forms two conidiophore types. Erect penicillate conidiophores producing catenulate non-septate hyaline conidia
form more frequently than Chalara -like conidiophores with funnel-shaped collarettes produce wedge-shaped phialoconidia. Although its morphological characters correspond more with Xenopolyscytalum, a three-region DNA analyses (ITS, 28S rDNA and EF-1α) of Infundichalara,
Xenopolyscytalum, and related Chalara species in the Helotiales confirm the phylogenetic position of the new species within Infundichalara. It differs from I. microchona by smaller phialides and wedge-shaped conidia.
