Growth optimal at 25 °C, slow or limited at 30 °C, absent at 35 °C. Colonies grew fast on PDA, CMD and MEA and slow on SNA. Colony radius after 72 h at 25 °C 67-71 mm on PDA, 68-71 mm on CMD, 51-55 mm on MEA and 21-24 mm on SNA. Aerial mycelia sparse on PDA after 72 h at 25 °C under 12 h photoperiod and conidiation developed within 48 h beginning at the inoculation point and progressed around, grey-white at first and slowly turning green. Diffusing pigment or distinctive odour absent. Aerial mycelia sparse and flocculence on MEA after 72 h at 20 °C under 12 h photoperiod. Conidia developed within 48 h beginning near the colony margin on MEA, grey-white at first and slowly turning green, transparent liquid secreted. Aerial mycelia few on SNA and CMD after 72 h at 25 °C, conidia formed around the inoculation point and in distinct concentric rings after 96 h under 12 h photoperiod on SNA and CMD, diffusing pigment not produced. Conidiophores and branches narrow and flexuous, tending to be regularly verticillate forming a pyramidal structure, each branch terminating in a cruciate whorl of up to five phialides.
