New cleistothecial Sordariaceae and a new family, Coniochaetaceae

Abstract

The family Sordariaceae is briefly defined and a list of cleistothecial genera given. Two species of Anixiella Saito & Minoura ex Cain, A. endodonta sp. nov., and A. monospora sp. nov. are described and a key to the four species of the genus included. Apodus deciduus gen. et sp. nov. is described. Two new combinations in Echinopodospora Robison, E. spinosa (Cailleux) Malloch & Cain and E. verruculosa (Cailleux) Malloch & Cain, are proposed to accept transfers from Tripterospora Cain and are followed by a key to species of Echinopodospora. The concept of Zopfiella Winter is broadened to include Z. pleuropora sp. nov. and three new combinations, Z. inermis (Cailleux) Malloch & Cain, Z. latipes (Lundqvist) Malloch & Cain, and Z. leucotricha (Speg.) Malloch & Cain, transferred from Tripterospora. A key to the six species of Zopfiella is presented. The new family Coniochaetaceae is proposed to accommodate the new genus Coniochaetidium and Coniochaeta (Sacc.) Massee. Two species of Coniochaetidium are described, C. ostreum sp. nov. and C. savoryi (Booth) Malloch & Cain, comb, nov., based on Thielavia savoryi Booth.
