| The genus Torulomyces was characterised by species that typically have conidiophores consisting of solitary phialides that produce long chains of conidia connected by disjunctors. Based on the phylogenetic position of P. lagena (generic ex-neotype), the genus and its seven species were transferred to Penicillium and classified in sect. Torulomyces along with P. cryptum and P. lassenii. The aim of this study was to review the species currently classified in sect. Torulomyces using morphology and phylogenies of the ITS, BenA, CaM and RPB2 regions. Based on our results, we accept 16 species in sect. Torulomyces, including 12 new species described as P. aeris, P. austricola, P. cantabricum, P. catalonicum, P. oregonense, P. marthae-christenseniae, P.... |

| Current literature accepts 17 species in Penicillium section Sclerotiora. Several produce colonies in bright yellow to orange colours and have monoverticillate conidiophores, apart from P. herquei, P. malachiteum and P. nodositatum, which are biverticillate. The focus of this paper is to refine the concepts of the species currently accepted in the section and introduce five new species, named after the Dutch Royal family as P. vanoranjei, P. maximae, P. amaliae, P. alexiae and P. arianeae. Penicillium vanoranjei produces orange (Dutch = oranje) colonies in culture, and is named after Willem-Alexander Claus George Ferdinand, ‘Zijne Koninklijke Hoogheid de Prins van Oranje’ (translated from Dutch as: ‘His Royal Highness the Prince of Orange’) and his family,... |

| The taxonomy of Talaromyces rugulosus, T. wortmannii and closely related species, classified in Talaromyces sect. Islandici, is reviewed in this paper. The species of Talaromyces sect. Islandici have restricted growth on MEA and CYA, generally have yellow mycelia and produce rugulosin and/or skyrin. They are important in biotechnology (e.g. T. rugulosus, T. wortmannii) and in medicine (e.g. T. piceus, T. radicus). The taxonomy of sect. Islandici was resolved using a combination of morphological, extrolite and phylogenetic data, using the Genealogical Concordance Phylogenetic Species Recognition (GCPSR) concept, with special focus on the T. rugulosus and T. wortmannii species complexes. In this paper, we synonymise T. variabilis, Penicillium... |

| During a survey of Penicillium spp. in soils from the diverse fynbos region in the Western Cape, South Africa, a number of previously undescribed species were isolated. Three of these belong to subg. Biverticillium sensu Pitt, recently incorporated into its previously associated teleomorph genus, Talaromyces s.str. These species displayed symmetrical biverticillate penicilli, acerose phialides and poor growth at reduced water activity, typical of this group. Morphological characters of the new species were compared to known Talaromyces species. The ITS and β-tubulin gene regions were used for phylogenetic comparisons, which confirmed the distinct nature of the three fynbos soil species described here as Talaromyces chloroloma sp. nov., T. ptychoconidium... |
