Note: This species is tentatively placed in Flectospora; in the phylogenetic analysis it grouped as a sister to F. laminata in a strongly supported clade. It is characterised by dark, glabrous, rostrate ascomata, ellipsoidal, hyaline, 0-1-septate ascospores and apricot pigment diffusing into the agar. Although anamorphs of the Tainosphaeria clade are conspicuous dematiaceous phialidic hyphomycetes such as Anacacumisporium [18], Phialogeniculata [16,17], Phialoturbella (this study) and Tainosphaeria [3], which readily sporulate in culture, the
anamorph of the present species is unknown. On the natural substrate only ascomata occurred and the culture derived from ascospores remained sterile. The species is included in the study to further characterise the emerging Tainosphaeria clade.
