MycoBank number: MB 7701; Index Fungorum number: IF 7701; Facesoffungi number: FoF 02102; 41 morphological species (Species Fungorum 2020), 20 species based on molecular data.

Type species – Clonostachys araucaria Corda

Notes – Bionectria was linked to Clonostachys by Rossman et al. (2013) and priority given to the older and commonly used name Clonostachys. We illustrate the sexual morph of Clonostachys rosea and asexual morph of C. byssicola (Figs. 48, 49).

Figure 48 – Clonostachys rosea (Material examined – THAILAND, Phayao Province, Chiang Kham District, on twigs of a dicotyledonous plant, R.H. Perera, 11 September 2017, Bion 17 (MFLU 19-0960), living culture MFLUCC 17-2632). a Herbarium material. b, c Ascomata on host (a dry, b after wet with water). d Section of ascoma. e Section of ostiole. f Section of peridium. g, h Asci. i-n Ascospores. o Germinating ascospore. p, q Colony on PDA. Scale bars: b, c = 200 µm, d = 100 µm, e, f = 50 µm, g, h = 20 µm, i-n = 10 µm, o = 20 µm.
