Mycologia Memoirs 9: 218 ( Tavares 1985). – Basionym: Asaphomyces gillerforsii Huggert, Svensk Botanisk Tidskrift 67: 245 ( Huggert 1973) [MB#309030]. –

Type: “Gtl, Etelhem, 6.VII.1971, L. Huggert (L.H. 1202), on Colenis immunda Sturm. (Holotype)”; UME. [ Sweden]

Diagnostic features

Thallus up to 85 µm long from foot to perithecial apex. Receptacle consisting of 3–6 superposed cells; only the uppermost of these cells, below the perithecium, isolates a unicellular secondary appendage ( Fig. 9B , sa). Perithecium about twice longer than broad. [Detailed description: Santamaria 2003]

Distribution and hosts

Known from Sweden on Colenis (type), Cyrtusa , and Xanthosphaera Fairmaire, 1859 (Col. Leiodidae ) ( Huggert 2010), and only on Colenis from Spain, France, Hungary ( Santamaria 1995b), Italy and Bulgaria ( Rossi et al. 2019a).

Remarks

First record from Denmark. The new find is not surprising given the geographical proximity of the Swedish type record.
