Coryne, Sarcoleotia or Ascocoryne?

The genus Coryne is now applied only to nonsexually reproducing fungi and is unavailable for Ascomycetes. However, the names Sarcoleotia Imai and Ascocoryne Groves and Wilson are both available for Ascomycetes and have been used to accommodate C. turficola. The only morphological feature that has been used to resolve this problem is the presence or absence of a gelatinous excipular layer within the apothecia (see photo). While most previous authors have described Coryne turficola as having gelatinous apothecial tissues Dennis (1971) reported the British collections to lack these features, and on that basis assigned it to Sarcoleotia as S. turficola Dennis. Morphologically, it also fits within the genus Ascocoryne. Studying the genetic relationships of the Helotiales, Wang and coworkers (2006) discovered that the genus Sarcoleotia sensu Schumacher and Sivertsen (1987) was made up of two separate genetic groups. One group (the Geoglossum clade) includes S. globosa, the type species of Sarcoleotia, which shares genetic, morphological and ecological similarity with the so-called earth tongue fungi, Geoglossum and Trichoglossum. A second group (the Ascocoryne clade) contains species having genetic similarity with the small genus Ascocoryne and includes C. turficola. Thus the genetic evidence
supports inclusion of C. turficola in Ascocoryne and not Sarcoleotia.

thank god …
