DEVELOPMENT 
they occasionally enclose one or two spores resembling 
those normally produced by the fungus. Their tips are 
often brightly coloured in Discomycetes, causing the brilliant 
hue of the disc in the cup-shaped species (Pezizae). They 
are a continuation of the vegetative hyphae. Certain 
species of Peziza are developed from sclerotia , which, as 
noted above, are a form of vegetative mycelium. They 
constitute the genus Sclerotinia.
