Index Fungorum number: IF 80993

Meliolaceae is the largest group of epifoliar fungi characterized by larviform ascospores and dark brown hyphae with phialides and 2-celled appressoria. Members of this family are unculturable, and host information is the primary criterion for their identification. The phylogenetic relationship of several genera in Meliolaceae are shown.

Fig. Phylogram generated from maximum likelihood analysis based on combined LSU, SSU and ITS sequence data. Nineteen strains are included in the combined analyses which comprised 2547 characters (834 characters for LSU, 1020 characters for SSU, 693 characters for ITS) after alignment. Tree topology of the maximum likelihood analysis is similar to the Bayesian analysis. The best RaxML tree with a final likelihood value of -12296.492874 is presented. Estimated base frequencies were as follows: A = 0.251820, C = 0.221366, G = 0.284447, T = 0.242367; substitution rates AC = 0.925122, AG = 3.316599, AT = 1.863343, CG = 0.262623, CT = 6.798329, GT = 1.000000; gamma distribution shape parameter a = 0.530371. Bootstrap support values for ML greater than 75% and Bayesian posterior probabilities greater than 0.95 are given near nodes respectively. The tree is rooted with Sordaria_fimicola (AFTOL-ID 216). Ex-type strains are in bold and black. The newly generated sequences are indicated in yellow.
