Penicillium poederi and P. tirolense, two new species of section Torulomyces
Here we describe two new species of the genus Penicillium section Torulomyces with solitary phialides. Penicillium poederi sp. nov. was isolated from volcanic soils in Iceland. Penicillium tirolense sp. nov. was isolated from a sporocarp of Serpula lacrymans. Both species are characterised by slow growth rates and the production of a brown soluble pigment on CYA, conidiophores with solitary ampulliform phialides with smooth-walled stipes and warty, globose conidia and with connectives without visible rings. The spores of. P. poederi are 2.5 μm diam, while the spores of P. tirolense are 2.0 μm diam. In a multigene phylogeny based on the ITS, BenA, CaM and RPB2 gene regions P. tubakianum and P. wollemiicola are the closest relatives of P. poederi. This species differs from P. tubakianum and P. wollemiicola by its growth rates and by its pigmentation. The holotype of P. poederi is IB2017/0007, while SF014017 (CBS 147622) is a culture derived from the holotype. The closest relatives of P. tirolense are P. austricola and P. riverlandense. It differs from P. austricola by lower growth rates on all tested media and temperatures and by its larger spores. It differs from P. riverlandense by lower growth rates and the absence of growth at 37 °C. The holotype of P. tirolense is IBF2019/0162, while SF015108 (CBS 147625) is a culture derived from the holotype.

More about this publication?
- Fungal Systematics and Evolution is an international, peer-reviewed, open-access, full colour, fast-track journal. Papers will include reviews, research articles, methodology papers, taxonomic monographs, and the description of fungi. The journal strongly supports good practice policies, and requires voucher specimens to be deposited in a fungarium, cultures in long-term genetic resource collection, sequences in GenBank, alignments in TreeBASE, and taxonomic novelties in MycoBank.
