Fig. 1 Austropleospora osteospermi (BRIP 52234, holotype). a Herbarium material. b Ascomata on host surface. c Section through ascoma. d Peridium. e Pseudoparaphyses. f Section through ostiole. g Immature ascus. h Mature bitunicate asci. i–l Ascospores. Scale bars: c = 50 μm, d–h = 20 μm, i–l = 10 μm.

Importance and distribution

Austropleospora comprises only one species known on stems of Chrysanthemoides monilifera subsp. rotundata (Asteraceae) in Australia (New South Wales). It causes small necrotic spots on the stems (Morin et al. 2010) and has potential for biological control of this major environmental weed and invasive species.
