Houbraken et al. ARTICLE Fig. 5. Growth of Penicillium psychrosexualis CBS 128036 on oatmeal agar at various incubation temperatures. A–F: 9, 12, 18, 24, 27 and 33 °C. on either side of the main ones, suggesting the presence of four ridges when observed with light microscopy, valves slightly roughened when viewed with SEM. Conidiophores terverticillate, slightly reduced conidiophores with smooth walled stipes on MEA and other agar media (PDA, PCA), on DG18 robust conidiophores with warted stipes, 3–4 µm. Metulae 10–15 × 3–4 µm. Conidiogenous cells (phialides) ampulliform, 8–10 × 3–4 µm. Conidia globose, smooth, 3.5–4 µm. Extrolites: Penicillium psychrosexualis produces the extrolites andrastin A, mycophenolic, patulin, roquefortine C and the uncharacterized extrolite tentatively named “fumu”. Furthermore, P. psychrosexualis produces the same odour as P. roqueforti. Diagnostic features: The growth on MEA containing 0.5 % acetic acid, the formation of cleistothecia at relatively low temperatures for the genus (9 °C) and fast growth rate on MEA, CYA and YES are diagnostic features of P. psychrosexualis. An overview of characteristics of P. psychrosexualis in comparison with other members of the series Roqueforti is shown in Table 2. Similar species and taxonomy: Phylogenetically P. psychrosexualis belongs to series Roqueforti. This species shares a fast growth rate on agar media, the ability to grow on MEA supplemented with 0.5 % acetic acid and forms conidiophores with warted stipes on DG18. This species produces the extrolites andrastin A, mycophenolic, patulin and roquefortine C and is chemically close to P. carneum. However, P. carneum also produces penitrem A, isofumigaclavine A and cyclopaldic aicd, while P. psychrosexualis produces the uncharacterised extrolite “fumu”. Penicillium psychrosexualis produces the same odour as P. roqueforti, and is thus very different from the strong odour of P. carneum. Another difference between P. psychrosexualis and the other members of the Roqueforti series is the production of cleistothecia by the former species. The growth rate on CYA at 30 °C is a diagnostic tool to differentiate between P. roqueforti and P. carneum on one hand and P. paneum on the other. Penicillium psychrosexualis has similar growth rates at 30 °C as P. roqueforti and P. carneum. This observation is concordant with the phylogeny, which also shows that these three species are closely related and that P. paneum is basal to these species. An overview of growth rates on CYA at various temperatures is shown in Fig. 6. Nomenclature: Although the new species produces cleistothecia, we decided to describe the taxon in Penicillium rather than Eupenicillium in accordance with the recommendations of Hawksworth (2010) on best-practice in such instances in a period when the rules of nomenclature that permit the dual naming of pleomorphic fungi are under revision. 176 i m a f U N G U S
