Type species – Testudina terrestris Bizz., Fl. Ven. Funghi 3: 303 (1885).
Notes – The monotypic genus Testudina was introduced by Bizzozero (1885). It was reported as parasitic on other fungi, or as saprobic on decaying wood of Abes and Pinus or on the fallen leaves of Taxus in Europe (Hawksworth & Booth 1974, Hawksworth 1979). Testudina had been earlier placed in Cephalothecaceae (Höhnel 1917b), then transferred to Pseudeurotiaceae (Malloch & Cain 1971), and von Arx (1971) assigned it to Testudinaceae based on its dark-walled ascomata and bitunicate asci with 1-septate dark ascospores (Hyde et al. 2013). Cultures and molecular data are unavailable for this genus (Schoch et al. 2009a, b, Suetrong et al. 2009) hence fresh collections are needed to affirm its natural taxonomic placement in this family (Zhang 2012b; Hyde et al. 2013).
