and substrate in certain areas become bright to deep green; conidial struc- 

 tures fairly abundant, produced on trailing hyphae or ropes of hyphae 

 chiefly near the perithecia.

 and are usually borne at right angles to the main hyphae; conidiophore walls 

 sometimes show a slight roughening. Penicilli are variable. Sterigmata
