Diagnostic features

Thallus bright yellow. Primary appendage consisting of (3–)4 superposed cells, where the 3 rd and 4 th bear one and two antheridia respectively. Perithecial tip with two very short and narrow lower lobes, two elongated upper lobes and two prominent lips surrounding the ostiole. [Detailed descriptions: Weir & Beakes 1996; Santamaria 2003; De Kesel 2011]

Distribution and hosts

A very common and widespread species. Reported on no less than 30 species and 20 genera of ladybird species (Col. Coccinellidae ) from the five continents ( Haelewaters et al. 2017). Also reported from Denmark (see Table 1 View Table 1 ).

Remarks

All the Danish records of this species come from specimens kept in dry museum collections. Perhaps a collective species including at least other seven undescribed taxa which have been revealed by sequencing thalli from multiple host species ( Haelewaters et al. 2018a; Haelewaters & De Kesel 2020). According to Haelewaters & De Kesel (2020), the Danish samples collected on Adalia Mulsant, 1850 fall into the named Adalia -clade and should belong to some yet undescribed species separate from H. virescens , a species what is suggested by Haelewaters et al. (2018a) to be restricted to fungi found on Chilocorus Leach, 1815 , as originally described.
