Coniella Höhn., Ber. Dt. Bot. Ges. 36(7): 316 (1918)

Index Fungorum number: IF 7753

Coniella was introduced by Höhnel (1918) with Coniella pulchella (= Coniella fragariae) as the type species. Coniella comprises of many plant pathogens (Van Niekerk et al. 2004, Mirabolfathy et al. 2012, Chethana et al. 2017), saprobes, and endophytes (Samuels et al. 1993, Ferreira et al. 1997, Alvarez et al. 2016). This genus has been subjected to many revisions. Alvarez et al. (2016) synonymized both Pilidiella and Schizoparme under Coniella. An updated phylogeny for the genus is provided.

Fig – Phylogenetic tree for Coniella based on maximum likelihood analysis of combined ITS, LSU, histone and TEF1-α sequence data. Thirty-three strains are included in the analyses comprising 2876 characters including gaps. Tree was rooted with Melanconiella sp. (CBS 110385). Tree topology of the ML analysis was similar to the MP and BI. The best scoring RAxML tree with a final likelihood value of -15134.164466 is presented. The matrix had 807 distinct alignment patterns, with 23.87% of undetermined characters or gaps. Estimated base frequencies were as follows; A = 0.249426, C = 0.245786, G = 0.256290, T = 0.248498; substitution rates AC = 0.996078, AG = 2.077237, AT = 1.158367, CG = 0.708887, CT = 4.169021, GT = 1.000000; gamma distribution shape parameter α = 0.145978. The maximum parsimonious dataset consisted of constant 2083, 512 parsimony-informative and 282 parsimony-uninformative characters. The parsimony analysis of the data matrix resulted in the maximum of five equally most parsimonious trees with a length of 2495 steps (CI = 0.532, RI = 0.583, RC = 0.310, HI = 0.468) in the first tree. RAxML and maximum parsimony bootstrap support values ≥ 60% and Bayesian posterior probabilities ≥ 0.90 are shown respectively near the nodes. The scale bar indicates 0.1 changes. The ex-type strains are in bold and the isolates of the current study in yellow.
