Penicillium poederi and P. tirolense, two new species of section Torulomyces

Abstract

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.

Seven New Species of Eurotiales (Ascomycota) Isolated from Tidal Flat Sediments in China

“…With the application of multiple loci phylogeny, the inter-specific relationships within these genera have become more clear [13][14][15]. Currently, the genus Aspergillus comprises 483 species belonging to 27 sections [11,[16][17][18][19][20][21][22], Penicillium contains 530 species in 33 sections [20,[22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38], and Talaromyces includes 204 species in 7 sections [6,18,32,[39][40][41][42]. They show a broad range of habitats, such as woody substratum, sandy soil, tidal flats, water, and indoor air [43][44][45][46][47].…”
