Type: “An allen Teilen der Körperoberfläche von Ocalea picata (Col., Staphylinidae, Aleocharinae). Das Material stammt aus Gesiebe aus Bruchwäldern bei Schwand/Nürnberg und Erlangen. Deutschland. Holotypus Abb. 39”. [Germany]
Diagnostic features
Cell III darkened, supporting two appendages: an outer blackened and irregularly branched primary appendage (Fig. 85D, pa), and an inner pale to variably darkened, simple or branched subsidiary appendage (Fig. 85D, arrow). Thalli with two to several secondary receptacles. Antheridia bearing two often very elongated secondary appendages, darker at the base, paler towards the apex, separated from the 4 th antheridial tier by a contrasting dark and constricted septum. Antheridia dark brown towards the base and margins, paler distally and around the middle area. Each antheridium includes four phialides. Stalk cell of perithecium narrowing and darkened near the base. [Detailed descriptions: Majewski 1994b; Weir 1994; Santamaria 1996c]
Distribution and hosts
Described from Germany on Ocalea picata (Stephens, 1832) (Col. Staphylinidae Aleocharinae), it has been later reported from Spain, United Kingdom, France, Belgium, Poland (Majewski 2008), and Denmark (Høier 2009). Also reported on Oxypoda (Col. Staphylinidae Aleocharinae) but these records probably belong to M. crassicaulis sp. nov.

Remarks
Distinctiveness of this species with respect to M. infuscatus (which is reported on Xantholininae rove beetles, Santamaria 1996c) should be revaluated with further studies. Dinaraea spp. is mentioned here for the first time as host for this species
