Notes: Species of Cylindrosympodium are characterized by cylindrical, hyaline or sub hyaline, erect conidiophores with cylindrical, septate hyaline conidia. Conidiogenous cells are conspicuous, flat-topped denticles and extended sympodially reduced from conidiophores (Paulus et al. 2003). In our analyses (Fig. 90), we tentatively accept this genus in Venturiaceae based on the sequence data of type species. However, the clade contains Cylindrosympodium is unstable within Venturiales, thus more sequence data are needed to clarify its placement within Venturiales
Fig. 90 Phylogram generated from maximum likelihood analysis (RAxML) of genera in Venturiales based on LSU, SSU and RPB2 sequence data. Maximum likelihood bootstrap values equal or above 70%, Bayesian posterior probabilities equal or above 0.90 (MLBS/ PP) are given at the nodes. An original isolate number is noted after the species name. The tree is rooted to Acrospermum compressum (M151) and Acrospermum longisporium (MFLU 17-2849). The extype strains are indicated in bold. Hyphen (-) represents support values below 70% MLBS and 0.90 PP
