Abstract:
Talaromyces minioluteus belongs to the section Trachyspermi, has a worldwide distribution
and has been found on various substrates, especially on various (stored) food commodities and indoor
environments. This species is phenotypically and phylogenetically closely related to T. chongqingensis
and T. minnesotensis. The phylogenetic and morphological analyses of 37 strains previously identified
as T. chongqingensis, T. minnesotensis and T. minioluteus revealed that this clade incudes eight species:
the accepted species T. chongqingensis, T. minnesotensis and T. minioluteus, the newly proposed species
T. calidominioluteus, T. africanus and T. germanicus, and the new combinations T. gaditanus (basionym
Penicillium gaditanum) and T. samsonii (basionym Penicillium samsonii). In this study, we give insight
of the phylogenetic relationships and provide detailed descriptions of the species belonging to this
clade. Macromorphological features, especially colony growth rates, texture and conidial colors on
agar media, are important characters for phenotypic differentiation between species.

SUPPLEMENTARY MATERIAL : Figure S1: Maximum Likelihood (ML) tree inferred based on the ITS sequence dataset with GenBank sequences (indicated in red). The BI posterior probabilities and ML bootstrap percentages are presented at the nodes. The fully supported branches are thickened and the BS/PP values are indicated with asterisk. Values less than 70% bs (ML) or less than 0.95 pp (Bayesian analysis) are indicated with a hyphen or not shown. The phylogram is rooted with T. flavus (CBS 310.38T) and T. sayulitensis (CBS 138204). T = ex-type, Table S1: Re-identification of T. minioluteus sequences present in GenBank.
