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. Citation: Kirchmair M, Embacher J, Heimdörfer D, Walch G, Neuhauser S (2022).

圆霉科青霉菌属两新种。
这里我们描述了两个新种青霉属部分的孤缘环菌。从冰岛火山土壤中分离到一株青霉菌。从一株泪蕨的孢子囊中分离到tirolense青霉。这两种植物的特点都是生长速度慢,在CYA上产生一种棕色可溶性色素,分生孢子孢子具有单独的壶形伞柄,柄壁光滑,有疣状球形分生孢子,连接物没有可见的环。的孢子P. poderi的孢子直径为2.5 μm, P. tirolense的孢子直径为2.0 μm。在基于ITS的多基因系统发育中,P. tubakianum和P. wollemiicola是P. poederi的近亲。该物种不同于P. tubakium和P. wollemiicola在其生长速度和色素沉着。P. poederi的完整型为IB2017/0007,而SF014017 (CBS 147622)是由完整型衍生的培养物。tirolense最近的亲戚是P. austricola和P. riverlandense。它与奥地利假单胞菌的不同之处在于,在所有测试的培养基和温度上的生长速度较低,孢子较大。它与P. riverlandense的不同之处在于生长速率较低,并且在37°C时不生长。P. tirolense的正型为IBF2019/0162,而SF015108 (CBS 147625)是由正型衍生的培养物。引用本文:kirchmaair M, Embacher J, Heimdörfer D, Walch G, Neuhauser S(2022)。标题圆霉科青霉属两新种。真菌分类学与进化(10):91-101。doi: 10.3114 / fuse.2022.10.03。
