Dipodomyces phloeocharidis T.Majewski MB#110622 Fig. 52C–G Acta Mycologica 17 (1–2): 55 (Majewski 1982). – Type: “ On Phloeocharis subtilissima Mann. (Col., Staphylinidae): Pomiechówek near Nowy Dwór Mazowiecki (Warszawa voivodeship), under the bark of dry, standing Pinus sylvestris in a pine wood close to the Wkra river,… 21.8.1977 (TM. … 1701 – holotype), leg. T. Majewski ”; KRAM. [Poland] Diagnostic features Primary appendage consisting of a main axis of three superposed cells (Fig. 52C, *), once to three times ramified in branches terminated by elongated antheridia. Primary septum slightly constricted and darkened (Fig. 52C, a). A spinous process (the original spore apex, sx) is found on the outer side of the 4 th cell of the primary appendage (Fig. 52F, sx). Perithecium asymmetric, with a strongly convex outer margin and a straight inner margin, gradually tapering towards the pointed apex which shows three long and one short acute lips. [Detailed description: Majewski 1994b] Distribution and hosts Known only from the type host in Poland. Collections examined from Denmark On Phloeocharis subtilissima Mannerheim, 1830 (Col. Staphylinidae Phloeocharinae) DENMARK – Nordøstsjaelland (NEZ) • Liseleje; 56°1.048′ N, 11°58.454′ E; PH81; 14 Sep. 2014; JP 39; JP det.; ZMUC C-F-122514. Remarks First record from Denmark and the first outside the type country. The host is quite common and widespread in Denmark and not difficult to find under dead and dry bark of various trees (both conifers and deciduous trees), but the fungus is apparently very rarely collected. This species greatly differs from D. monstruosus, the type of the genus, and its inclusion in Dipodomyces requires an emendation of the generic diagnosis (Majewski 1982), or the description of a new genus. The trichogyne of this species shows an unusual subspherical shape (Fig. 52G, tr). Worth mentioning is the presence of reduced male thalli with apparently functional antheridia, accompanying the normal monoecious thalli (Fig. 52E). A photo of this species is given here for the first time.
