Notes:
Colonies on CYA 40-50 mm diam, plane, low and velutinous, usually quite dense; mycelium white; conidial production heavy, brown (Dark Blonde to Camel, 5-6D4); reverse pale to dull brown or yellow brown. Colonies on MEA 40-60 mm diam, similar to those on CYA or less dense. Colonies on G25N 18-22 mm diam, plane or irregularly wrinkled, low and sparse; conidial production light, pale brown; brown soluble pigment sometimes produced; reverse brown. No growth at 5°C. Colonies at 37°C growing very rapidly, 50 mm or more diam, of similar appearance to those on CYA at 25°C.Conidiophores borne from surface hyphae, stipes 100-250 μm long, smooth walled; vesicles 15-20 μm diam, fertile over the upper hemisphere, with densely packed, short, narrow metulae and phialides, both 5-8 μm long; conidia spherical, very small, 1.8-2.5 μm diam, smooth walled, at maturity borne in long, well defined columns.Distinctive featuresVelutinous colonies formed at both 25°C and 37°C, uniformly brown, with no other colouration, and minute conidia borne in long columns make Aspergillus terreus a distinctive species.

Patient MB X rays and CT scans. Chronic calcified maxillary sinusitis, patient had a palate defect.A. fumigatus cultured.
Images A&B Plain X rays antero-posterior and lateral, pre-operatively of Pt MB aged 76 who presented with unilateral nasal stuffiness and difficulty getting dentures fitted. She had hda these symptoms for many years. A large irregular calcified mass can be seen replacing the right maxillary sinus.
Images C D & E Coronal CT scan images of Pt MB showing a completely obstructed nasal cavity bilaterally and loss of internal nasal architecture. On the right side is large lamellar calcified lesion embedded in the extensive inflammatory material. Loss of bony margins is seen in numerous locations. This material was all removed surgically and showed mostly necrotic debris with Charcot-Leyden crystals and a few eosinophils and degenerate fungal hyphae. Aspergillus fumigatus was cultured from the material, especially infero-laterally on the right.
Image F Photograph through the mouth post-operatively showing the palate and a large defect in its right side. Through the defect can be seen the interior of the right maxillary sinus and nasal cavity with the inferior turbinate just visible.
