asal cell and two short branches terminated by one or two antheridia. Stalkcell of perithecium flattened, situated obliquely, or elongated, perithecium(75-)95-136(-145) x (32-)40-55(-78) µm, about 2/3 free, ovate, slightlyasymmetrical, with a more convex posterior margin, distinct subapical spotsand prominent rounded posterior lips. Ostiolum mostly abaxially oriented; theperithecium than is asymmetrical.Studied material [Coleoptera, Carabidae, Harpalinae]:Bradycellus harpalinus (Serville):Tilburg TWM, Kaaistoep-west, 128.8-394.6. Licht, 31.viii.08.Haelewaters 8a, 8b, 8c.Bradycellus verbasci (Duftschmid):Tilburg TWM, Kaaistoep-west, 128.8-394.6. Licht, 6.viii.08.Haelewaters 7a, 7b, 7c.Specificity and geographical distribution:So far on species of the genus Bradycellus Erichson and TrichocellusGanglbauer in many European countries, on Madeira Island, and in Mexico(MAJEWSKI, 1994). Type on Bradycellus caucasicus (Chaudoir) in Finland.Remarks:DE KESEL (1997) mentions that thallus length varies depending on the speciesof host. Thalli of of Bradycellus harpalinus and B. verbasci (180-420 µm) differsignificantly from those of B. ruficollis and Trichocellus placidus (160-200 µm).Laboulbenia eubradycelli is new for the mycoflora of The Netherlands.4.3.

Picture by Danny Haelewaters (2010).Thallus (110-)542-572(-590)[830] µm long, yellow-brownish, perithecium andupper receptacle darkened. Receptacle (80-)447-477(-500)[725] µm long,stout or slender, variable in length; cell I cuniform, at least 2 times longer thanbroad, cell II stout, always longer than cell I, 2-10 times longer than broad orslender, cylindrical, often narrowed and nearly hyaline in its upper half, cell IIIP a g e | 89
