Figure 1.
Examples for the macro- and micromorphology of the investigated Mortierellales strains.
Lobed growth of Mortierella capitata on MEA. (a). Micromorphology of M. verticillata (b), arrows indicate the sporangiophores after dehiscence. Chlamydospore of M. gemmifera (c). Sporangiophores with sporangiospores (d) and stylospores (e) of M. polycephala. Stylospores of M. polygonia produced on MEA (f) and its chlamydospores produced on OA (g). Sporangiophores and sporangia of M. amoeboidea (h). Sporangiophores of M. biramosa (i), the arrow indicates the characteristic collar remaining at the apex after the dehiscence of the sporangium. Stylospores of M. indohii (j). Sporangia of Dissophora decumbens (k). Chlamydospores (l) and sporangium (m) produced by D. ornata. Sporangiophores and sporangia after the dehiscence of M. turficola (n). Branching sporangiophores and sporangiospores of Gamsiella multidivaricata (o). Sporangia and sporangiophores produced by M. mutabilis on MEA (p) and its branching sporangiophores produced on OA (q). Sporangia of M. exigua (r). In each panel, the lengths of scale bars denote 10 µm.

Saturation of log likelihood (lnL) values as a function of model complexity, calculated as a mean of the likelihoods of post–burn–in trees.
(a) Comparison of all 15 partitioned models. Figure shows that the indel matrix is best described by one–parameter models, which show up as local plateaus (see arrowheads) in the saturation of likelihoods. (b) Comparison of MCMC analyses performed by using the mixture models (in BayesPhylogenies) only with 1 to 7 GTR+ Γ matrices.

Figure 3.
The 50% Majority Rule consensus phylogram inferred from the nuclear ribosomal sequence data of 90 Mortierellales strains using BayesPhylogenies, under a model with 5 GTR+ Γ matrices for each of the six partitions.
Numbers above branches indicate Maximum Parsimony (MPBS), Maximum Likelihood bootstrap (MLBS) percentages and Bayesian posterior probabilities (BBP), respectively. Missing or weakly supported nodes (<50% or 0.5) are denoted by a “–”.
