Jobellisia M.E. Barr, Mycotaxon 46: 60 (1993)
Index Fungorum number: IF 26310
Jobellisia comprises nine species in Index Fungorum (2020), and only three have sequence data in GenBank, i.e., Jobellisia fraterna, J. guangdongensis and J. luteola (type species). Jobellisia is characterized by superficial ascomata with light reddish apex, reddish-brown peridium, cylindrical asci with a refractive apical ring and ellipsoidal ascospores (Barr 1993). The asexual morph of Jobellisia is still unknown. Placement of the Jobellisia species in a phylogentic analysis is presented.
Phylogram generated from maximum likelihood analysis based on combined LSU and ITS sequence data. Nineteen strains are included in the combined analyses, which comprised 1395 characters (860 characters for LSU, 535 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 -5328.282817 is presented. Estimated base frequencies were as follows: A = 0.241807, C = 0.240515, G = 0.317101, T = 0.200577; substitution rates AC = 0.824389, AG = 2.607842, AT = 1.742277, CG = 1.207733, CT = 7.488055, GT = 1.000000; gamma distribution shape parameter a = 0.296714. For both LSU and ITS gene regions, GTR+I+G was applied as the evolutionary model. Bootstrap support values for ML greater than 70% and Bayesian posterior probabilities greater than 0.90 are given near the nodes respectively. The tree is rooted with Pleospora herbarum (CBS 191.86). Ex-type strains are in bold and black. The newly generated sequence is indicated in yellow.
