The following new combinations are proposed: P. aloides (Sordaria aloides Fuckel), P. apiculifera (S. apiculifera Speg.), P. argentinensis (S. argentinensis Speg.), P. austro-americana (Hypocopra austro-americana Speg.), P. ellisiana (Pleurage ellisiana Griff.), P. longicollis (Schizothecium longicollis Ames), P. seminuda (Sordaria seminuda Griff.), P. tarvisina (Philocopra tarvisina Sacc.), and P. vesticola (Sphaeria vesticola Berk. & Br.).
