Proceedings of the American Academy of Arts and Sciences 35: 443 (Thaxter 1900). –
Type: [Not designated] [Ind. loc.] “ On Dyschirius globosus Herbst., Hope Coll., No. 349, England; on D. salinus Schaum., British Museum, No. 582, Europe”; FH. [According to Majewski (2008), Tavares (1985) designated a lectotype but we don’t see any explicit reference to this in her work]
Misgomyces lavagnei F.Picard (Picard 1913: 520) [Not registered in MycoBank]
Diagnostic features
Receptacle consisting of a lower uniseriate row of 4–25 cells derived from cell II. Cell III irregularly divided into several small cells. Primary septum constricted and darkened. Primary appendage irregular, consisting of some embedded antheridia giving rise to short efferent necks, and a variable number of cells, some of them giving rise to sterile branches. [Detailed descriptions: Thaxter 1931; Sugiyama 1973; Santamaria 1989; Majewski 1994b]
Distribution and hosts
Occurs on species of the genera Dyschirius Bonelli, 1810 and Dyschiriodes Jeannel, 1941 (Col. Carabidae) and rarely of the genus Bledius Leach, 1819 (Col. Staphylinidae Oxytelinae). The fungus on Bledius was described as M. lavagnei. Widely distributed in Europe (Austria, Denmark, Finland, France, Germany, Greece, the Netherlands, Hungary, Ireland, Italy, Poland, Romania, Spain, Switzerland, United Kingdom, Russia), Asia (Iran, Israel, Japan), Africa (Algeria, Canary Islands) and America (USA) (Santamaria et al. 1991). Subsequent records are from Belgium (De Kesel & Rammeloo 1992), India (Kaur & Mukerji 1996a), Korea (Lee & Na 1998), Lithuania (Markovskaja 2000), China (Shen & Ye 2006), Latvia (De Kesel & Krastina De Kesel 2006), Czech Republic, Slovakia (Rossi et al. 2010), Sweden (Huggert 2010), Turkey (Rossi 2016), Bulgaria, Namibia, Mongolia, Kazakhstan, Albania (Rossi et al. 2019a), and South Africa (Goldmann & Weir 2018).

Remarks
The length of thalli is very variable, from very short for thalli found on tarsi (Fig. 23B), to the mostly usual elongated thalli which are found on the upper rear surface of pronotum of their hosts (Figs 23A, 103A). Despite all the experienced adjustments, this genus is still in need of some revision. Without going any further, the structure of the antheridia is not yet well understood. According to Rossi et al. (2019a), antheridia are of the simple type, instead of the compound type described by Tavares (1985).
