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)

Basidiomycetes

Basidiomycetes are divided into two sub-classes;

1. Heterobasidiomycetidae: the basidium is either septate or deeply divided and the basidiospores are capable of germinating by repetition. These include the rusts, the smuts and the jelly fungi. Example: i) Tremellales ii) Tremellaceae iii) Auriculariaceae
2. Homobasidiomycetidae: the basidium in neither septate nor deeply divides and the basidio-spores usually germinate by a germ tube. The Fungi included in this sub-class are very common and are generally known as mushrooms, toadstools, puffballs, stinkhorn, bird's-nest fungi and bracket fungi bracket fungi

Media for culture fungi

Media for culture fungi

Water Agar (WA)--use for isolating fungi from surface-sterilized substrates.

Antibiotic Agar (AA)--use for isolating fungi from substrates not readily surface-sterilized, or to clean up a culture contaminated with bacteria.

Acidified Cornmeal Agar (ACMA)--use for isolating fungi from substrates that are likely to be contaminated with bacteria. Not a substitute for AA, but the acidity inhibits bacteria and the medium supports the growth of a wide range of fungi.

Cornmeal Agar (CMA)--use for growing a wide range of fungi, particularly members of the Fungi imperfecti; provides a good balance of mycelial growth and sporulation.

Potato Carrot Agar (PCA)--considered a relatively weak medium somewhat comparable to CMA, good for some Fungi imperfecti.

Malt Agar (MA)--lacks peptone, and is useful for culturing many Ascomycota; sporulation in some species is inhibited by peptone.

Malt Extract Agar (MEA)--a good growth medium for soil fungi, fungi isolated from wood, basidiomycetes, etc. An all-purpose type of medium.

Potato Dextrose Agar (PDA)--a relatively rich medium for growing a wide range of fungi.

Potato Dextrose-Yeast Extract Agar (PDYA)---good for growing cultures derived from mushrooms.

Agaricus sp.

Agaricus sp., a fleshy species and one of the true mushrooms, with purplish brown spores.

Hygrophorus sp.

Hygrophorus sp.


Order: Agaricales
Family: Hygrophoraceae
Genus: Hygrophorus

The genus of Hygrophorus are colourful, producing red, orange or yellow basidiocarps.
