Homobasidiomycetidae

The homobasidiomycetidae are divided into two distinct groups;

1. Hymenomycetes: characterised by basidia which develop in a well defined hymenium which becomes exposed even when the spores are still undeveloped. Examples of Order :1) Aphyllophorales (Family: Thelephoraceae, Clavariaceae, Hydnaceae, Polyporaceae) 2) Agaricales ( Hygrophoraceae, Tricholomataceae, Amaniataceae, Agaricaceae, Coprinaceae, Bolbitaceae, Cortinariaceae, Boletaceae)
2. Gasteromycetes: having poorly defined hymenia closed, at least at an early stage of the development of their fruit bodies; basidiospores are not violenlty discharged from their sterigmata. Examples of Order 1) Phallales (Family: Phallaceace, Clathraceae), 2) Nidulariales (Family: Nidulariaceae, Sphaerobolaceae) 3) Lycoperdales (Family: Lycoperdaceae, Geastraceae) 4) Hymenogastrales (Family: Podaxaceae)
