2. • Peziza a commonly called cup fungi,
is a genus of saprophytic fungi that
grow on the ground, rotting wood,
or dung
• A fruiting body of species
of Peziza is mostly cup or disc-
shaped called an apothecium.
shaped called an apothecium.
• The apothecia are mostly sessile but
sometimes stalked, minute to very
large (0.5-10.0 cm or more in
diameter), brightly colored (but
lacking carotenoids) to dark brown;
smooth, velvety, hairy or bristly.
• The genus contains more than 100
species
4. • Asexual reproduction takes place by conidia and
chlamydospores.
• The conidia are formed exogenously at the tip of
conidiophores.
Asexual Reproduction
• Conidia germinate to form the new mycelium.
• Some intercalary, thick-walled cells are formed in
the mycelium. These are chlamydospores. On
germination, they form new mycelium.
5. Sexual Reproduction
• Sexual Reproduction takes place by means of antheridium and
ascogonium.
• Sexual fusion results into a bright coloured, cup-shaped, large and
sessile apothecial type of fruiting body.
6. • Apothecium consists of
mycelium with a basal
hypothecium.
• Hymenium region consists of
many fertile asci and sterile
paraphyses.
Apothecium
• Sub-hymenium is made up of
pseudo- parenchymatous
hyphae which later on form the
peridium of the cup.
• In each ascus are present eight
uninucleate ascospores which
form the new mycelium on
germination.
