MB#804337

Fig. 46F–H

Nova Hedwigia 98 (1–2): 114 (Haelewaters et al. 2014). –

Type: “ On Bibloporus bicolor (Denny, 1825) ( Coleoptera, Staphylinidae , Pselaphinae ), collected in Haren , Harener Wildernis (Groningen), N 53°10′ E 6°38′, 2.ix.2000, under bark of standing dead Alnus glutinosa tree, leg. and det. O.Vorst (cOV), D.Haelewaters 60d (HOLOTYPE, 1 mature thallus, found on elytra, BR MYCO 173758 –31)”; BR.

Diagnostic features

Cell II separated from cell III by a strongly oblique septum. Basal part of cell VI not or slightly constricted, showing a cytoplasmatic constraint or septum-like marking above septum II–VI ( Fig. 46G–H , arrows). Perithecial apex rounded.

Distribution and hosts

Only known from the type, on Bibloporus bicolor (Denny, 1825) (Col. Staphylinidae Pselaphinae ) from the Netherlands.

Collections examined from Denmark

On Bibloporus minutus RAffrAY, 1914 (Col. Staphylinidae Pselaphinae ) DENMARK – Lolland, Falster, Møn (LFM) • Løgnor ; 54°46.987′ N, 11°48.999′ E; PF87; 16 Dec. 2014; K.B. Nielsen 81; JP det.; ZMUC C-F-122556 .

Remarks

First record from Denmark. Related to Bordea strangulata (Thaxt.) R.K.Benj. which occurs on Euconnus - like beetles (Col. Staphylinidae Scydmaeninae ) from Guatemala ( Benjamin 2001). Constriction of cell VI is present in both species, although it is different. The Danish record is the first for this species after its original description. A photo of this species is given here for the first time.
