Remarks (public):Notes – Aspergillus oxumiae is phylogenetically related with the species Aspergillus serratalhadensis included in the section Nigri, but it is clearly a different species. The morphological characteristics distinguishing A. oxumiae from this specie are as follow: A. oxumiae grows slower than this specie on CYA and YES 25 ºC and grows more fast on OA 25 ºC. A. oxumiae not produce acid on CREA, the stipe and phialide is bigger than A. serratalhadensis and the vesicle are smaller. All macroscopic and microscopic measurements were done twice, independently, for isolate CCDCA 11546.

Description:Conidial heads radiate. Conidiophores uniseriate. Stipes smooth, frequently septate 48−890(−931) × 2−5(−7) μm, sometimes with subterminal branches and mycelial coilings occasionally present. Vesicles pyriform to subglobose, pigmented, 8−20(−30) × 6.5−21(−30) μm (av. 12 ± 3.6 × 11 ± 3.2), phialides 4−13(−20) × 2−8 μm (av. 8 ± 2.7 × 4 ± 1.0) covering half to upper half of vesicle. Conidia globose to subglobose 3−7 × 3.5−7 μm (av. 5 ± 0.77 × 5 ± 0.81), brown to greyish brown, with coarsely roughened to echinulate surface, average width/length = 1 ± 0.03, n = 74. Sclerotia observed.
