Fig. 69. Peyritschiella spp. A –C . P. princeps (Thaxt.) I.I.Tav. Mature thalli. In C arrows point to horizontal septa that divide the first two contiguous cells in the lower tier. – D . P. vulgata (Thaxt.) I.I.Tav. Mature thallus. Scale bars: 50 µm. Photographs from slides ZMUC C-F-122535 (A–B), ZMUC C-F-122536 (C), ZMUC C-F-123973 (D). Diagnostic features Thallus symmetrical, up to 250 × 120 µm (length × width). Lower tier of cells blackened, almost entirely opaque except for the central area. Middle tier of cells blackened outwards; extending with laterally superposed cells forming strip-like expansions exceeding in length the upper part of the receptacle. Perithecia (2–) 4 in number, with the apices bearing auricles. [Detailed descriptions: Thaxter 1908 ; Sugiyama 1973 ; Santamaria 1989 ; Majewski 1999 ] Distribution and hosts Grows on species of Philonthus and its allies (like Spatulonthus ) (Col. Staphylinidae Staphylininae ). Widespread and reported from the five continents. Santamaria et al. (1991) gather records from these countries in Europe : Austria , Finland , France , the Netherlands , Hungary , Italy , Spain , United Kingdom , Russia ; Africa : Algeria , Cameroon , Ethiopia , Madeira, St Helena; America : Argentina , Chile , Grenada , Guatemala , Jamaica , Mexico , Nicaragua , Panama , Uruguay , USA ; Asia :Arabia, Bali, China ; and Oceania : Australia . Subsequent to that check-list, P. vulgata has been reported from Korea ( Lee & Choi 1992b ), India ( Kaur & Mukerji 1996b ), Poland ( Majewski 1999 ), Slovakia , Czech Republic ( Rossi et al. 2010 ), and Bulgaria ( Rossi et al. 2019a ). Collections examined from Denmark On Philonthus quisquiliarius (Gyllenhal, 1810) (Col. Staphylinidae Staphylininae ) DENMARK – Lolland, Falster, Møn (LFM) • Gedser Odde ; 54°33.687′ N , 11°57.806′ E ; PF95; 21 Apr. 2019 ; JP 1427 ; JP det.; ZMUC C-F-123973 . Remarks First record from Denmark . This species has been described as a variable species including atypical thalli lacking the lateral blackish strips formed from the middle tier and with perithecia where the apices lack auricles. All the Danish thalli studied belong to the typical form.
