Lulworthiaceae Kohlm., Spatafora & Volkm.-Kohlm., Mycologia 92(3): 456 (2000)

Index Fungorum number: IF 82091

Lulworthiaceae was introduced to accommodate several species belonging to Lulworthia and Lindra with filamentous ascospores (Kohlmeyer et al. 2000). This family comprises the genera, Halazoon, Haloguignardia, Hydea, Kohlmeyeriella, Lindra, Lulwoidea, Lulworthia, Matsusporium, Moleospora, Moromyces, Orbimyces, Spathulospora and Sammeyersia (Jones et al. 2015, Maharachchikumbura et al. 2016, Abdel-Wahab et al. 2017, Hyde et al. 2020a). However, the placements of Haloguignardia and Spathulospora in  Lulworthiales is still doubtful (Inderbitzin et al. 2004, Campbell et al. 2005, Jones et al. 2009, Hyde et al. 2020a). An updated phylogeny for the genus is presented.

Phylogram generated from maximum likelihood analysis based on combined LSU, SSU and ITS sequence data. Thirty-seven strains are included in the combined analyses which comprised 2770 characters (930 characters for LSU, 1057 characters for SSU, 783 characters for ITS) after alignment. The GTR+I+G evolutionary model was applied forTree topology of the maximum likelihood analysis is similar to the Bayesian analysis. The best RaxML tree with a final likelihood value of -17530.495296 is presented. Estimated base frequencies were as follows: A = 0.249147, C = 0.237452, G = 0.292161, T = 0.221241; substitution rates AC = 0.972203, AG = 2.135907, AT = 1.056736, CG = 1.215059, CT = 6.333743, GT = 1.000000; gamma distribution shape parameter a = 0.341853. 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 Fuscosporella pyriformis (MFLUCC 16-0570) and Parafuscosporella mucosa (MFLUCC 16-0571). Ex-type strains are in bold and black. The newly generated sequences are indicated in yellow.
