Canalisporium Nawawi & Kuthubutheen, Mycotaxon 34(2): 477 (1989)
Index Fungorum number: IF 11041
Canalisporium is the largest genus in Savoryellaceae comprising 16 species (Index Fungorum 2020). The latest treatment of Canalisporium was carried out by Hyde et al. (2020a) and this is followed in this study.
Phylogram generated from maximum likelihood analysis based on combined ITS, LSU and SSU sequence data. Twenty-two strains are included in the combined analyses which comprised 2756 characters (741 characters for ITS, 846 characters for LSU, 1169 characters for SSU) after alignment. For all the gene regions, GTR+I+G was applied as the evolutionary model. Tree topology of the maximum likelihood analysis is similar to the Bayesian analysis. The best RaxML tree with a final likelihood value of -7912.691553 is presented. Estimated base frequencies were as follows: A = 0.225339, C = 0.258163, G = 0.306839, T = 0.209659; substitution rates AC = 1.225977, AG = 3.213328, AT = 1.956116, CG = 0.495328, CT = 6.284499, GT = 1.000000; gamma distribution shape parameter a = 0.162166. Bootstrap support values for ML greater than 80% and Bayesian posterior probabilities greater than 0.95 are given near the nodes respectively. The tree is rooted with pleurothecium semifecundum (CBS 131271). Ex-type strains are in bold and black. The newly generated sequence is indicated in yellow.
