Chloridium humicola (S.C. Jong & E.E. Davis) T.P. Wei & Y.L. Jiang , comb. nov.

MycoBank: MB 842520

Basionym:— Phialocephala humicola S.C. Jong & E.E. Davis, Mycologia 64 (6): 1352 (1972).

Description:— Jong & Davis (1972).

Notes:— Phialocephala humicola was initially reported as saprophytes on soil in New Jersey, USA ( Jong & Davis 1972). Although we did not isolate the type strains, we have examined the DNA sequence data from ex-type culture and another culture deposited under that species name in GenBank. Multi-locus phylogenetic analyses indicate that this species formed a well-supported monophyletic lineage in Chloridium , and can be differentiated from the other species in Chloridium by its morphological characteristics and DNA sequence data ( Fig 1 , 2 ; Jong & Davis 1972). Based on morphological characters and phylogenetic analyses, we therefore transferred P. humicola to Chloridium as a new combination.

Figures

FIGURE 1. Phylogram of RAxML analysis based on a combined ITS and LSU sequence dataset within Chloridium. Adautomilanezia caesalpiniae was used as outgroup. Bootstrap support values for Maximum likelihood and Maximum parsimony greater than 50%, and Bayesian posterior probabilities equal to or greater than 0.8 are indicated at the nodes (ML/BI/MP). Type strains are highlighted by a “*”, and our strain is in bold.

FIGURE 2. Splitgraphs showing the results of the pairwise homoplasy index (PHI) test of newly described taxa and closely related species using both LogDet transformation and splits decomposition. PHI test results (Φw) <0.05 indicate significant recombination within the dataset. Type strains and new taxa are indicated with “*” and bold, respectively.
