SVRCEK. (1985) revised all those species described by VELENOVSKY in Helotium. He corrected the latter's ascospore measurements and placed H. dumbirense in synonymy with "Rutstroemia" macrospora (PECK) KANOUSE, a common species in North America, Australia and eastern Asia, which is now included in the genus Ciboria, as C. peckiana (COOKE) KORF (Sclerotiniaceae). SPOONER (1988) examined a specimen from Wales labelled as Rutstroemia macrospora, collected by S C PORTER, and two further collections from Slovakia made by R W G. DENNIS. He concluded that the European material is clearly different from the typical C. peckiana (although very close) and transferred Helotium dumbirense to the genus Ciboria as Ciboria dumbirensis. Here and in SPOONER (1987: 306) he considered both species as clearly belonging in the Sclerotiniaceae, with a most close relationship with the lignicolous Ciboria bolaris (BATSCH: FR.) FUCKEL. In 1993, SVRCEK reconsidered his concept of Rutstroemia macrospora based on the examination often collections from the Czech Republic and Slovakia. He also found the European collections to be distinct from the species of PECK. He did not adopt the placement in Ciboria (apparently he was unaware of SPOONER'S paper) but erected the new monotypic genus Tatraea, based on Helotium dumbirense. Although SVRCEK (1993) never discussed its exact taxonomical position, the genus Tatraea apparently belongs in the Leotiaceae (cf. HAWKSWORTH & al. 1995), considering that he placed it close to the genus Hymenoscyphus S F. GRAY (= Helotium ss auct.) („probabiliter ex affinitate generis Hymenoscyphus"). Ombrophila decolorans (BERK. & CURTIS) SACC. was restudied by HB from a ?syntype [K.(M) 59185, no date, USA, Alabama, no locality, on wood of Quercus, PETERS, Fig. 11]. This was filed in SEAVER (1961) as a later synonym of Ciboria peckiana, [as „Calycina macrospora (PECK) SEAVER"] The apical apparatus also clearly belongs to the Tatraea-type, differing from T. dumbirensis in being thinner, with the distinct amyloid zones occupying the complete dome. Ciboria peckiana is therefore considered to belong in Tatraea, and the new combination is here proposed. Very probably, the two Australasian taxa treated by SPOONER (1987) as forms of Ciboria peckiana also belong in Tatraea, although one is described with inamyloid asci. …. the complete section Lignicola (excluding C. bolaris which is related to the genus Rutstroemia P. KARST.) described by SPOONER within Ciboria must be considered a synonym of Tatraea. However, without studying especially the apical apparatus in detail, further new combinations seem to be premature. Furthermore, the described differences among the taxa are not always very clear.
