Remarks (internal):This generic description differs slightly from Sogonov et al. (2008). Perithecia were found to be aggregated in groups of up to 11 instead of five. A minimal stroma was observed for G. macounii and G. racemula. According to Barr (1978) appendages are present on ascospores of G. tormentillae; no type or other material of this species was available for examination.
