Notes on the Laboulbeniales (Ascomycota) parasitic on Diptera from Portugal and other countries

Eighteen species of Stigmatomyces are reported for the first time from continental Portugal and/or from the Azores. These are Stigmatomyces asteiae W. Rossi et Cesari, Stigmatomyces athyroglossae W. Rossi et Cesari, Stigmatomycescanzonerii W. Rossi et Cesari, Stigmatomyces ceratophorus Whisler, Stigmatomyces constrictus Thaxt., Stigmatomyces crassicollis Thaxt., Stigmatomyces divergatus Thaxt., Stigmatomyces discocerinae Thaxt., Stigmatomyces ensinae Thaxt., Stigmatomyces cf. ephydrae L. Mercier et R. A. Poiss., Stigmatomycesgeomyzae W. Rossi et Cesari, Stigmatomyces limnophorae Thaxt., Stigmatomyces majewskii H. L. Dainat, Manier et Balazuc, Stigmatomyces papuanus Thaxt., Stigmatomycesplatensis Speg., Stigmatomyces ptylomyiae Thaxt. and Stigmatomyces purpureus Thaxt., Stigmatomyces rugosus Thaxt. New records of these species are also reported from Australia, Canada, Canary Islands (Spain), Costa Rica, Cuba, Ecuador, Finland, Germany, Great Britain, Greece, Kenya, Hungary, Israel, Kyrgyzstan, Lebanon, Morocco, Saudi Arabia, Sierra Leone, Taiwan, Thailand, Turkey, Uganda, United Arab Emirates, USA, Yemen and Zimbabwe. The new records increase, sometimes considerably, information about distribution of these parasites. Two synonymies are also established: Stigmatomyces autriquei Balazuc=Stigmatomyces ensinae Thaxt.; Stigmatomyces psilopae Thaxt. var. camarguensis H. L. Dainat et J. Dainat =S. rugosus Thaxt.
