MB#103298

Fig. 9D–E

Acta Mycologica 19: 185 ( Majewski 1986a). –

Type: “ On Proteinus brachypterus F. (Col. Staphylinidae ): Bieszczady Mts., Wetlina (Krosno voiv.), under bark of overthrown trunks of Fagus sylvatica in Fagetum on the eastern mountain-side of Jawornik , about 700 m above sea level, 2.6.1974 (holotype, TM. 1418 )”; KRAM. [ Poland]

Diagnostic features

Thalli with 1–2 perithecia, if two, then borne on opposite sides of the 5 th receptacular cell. Fourth cell of the receptacle larger than others above and below. Secondary appendages ± branched, continuing the six- to eight-celled receptacle. Primary appendage two-celled, concealed, lateral to the distal cell of receptacle (Fig. D, pa). [Detailed descriptions: Santamaria 1991, 2003; Majewski 1994b]

Distribution and hosts

Only known from Poland on Acrulia Thomson, 1858 and Proteinus Latreille, 1796 and also from Spain on Baptolinus affinis (Paykull, 1789) ( Santamaria 1989) . All hosts belong to Col. Staphylinidae .

Remarks

First record from Denmark. According to Tavares (in litt.) this species may belong to the genus Carpophoromyces . Thalli from Acrulia represent a reduced form where the second perithecium is shown at the one-celled initial stage (cell d), and maybe it never develops beyond that ( Majewski 1994b).
