Sparassis crispa

Cauliflower fungus, Cauliflower conifer

Description and Significance

"Sparassis crispa" is a species in the Fungi kingdom found all over the world in northern temperate forests (1). They are brown rot fungi which grow at the base of conifer trees such as pine, spruce, cedar, and larch (2). The fruiting body of the fungus is known as cauliflower fungus because of the resemblance it has with the vegetable, with flat and curly lobes that come in cream, white, and yellow. Cauliflower fungus are an edible mushroom, known for their culinary and medicinal benefits and are prized throughout Europe and Asia for their mild flavor and multiple health benefits such as anti-tumor and anti-cancer (1).

Life Cycle, Cell Structure, Metabolism

"Sparassis crispa (S. crispa)" are members of the phylum Basidiomycota. The species exhibits bifactorial heterothallism (4), requiring two compatible partners to produce sexual spores and mating alleles with two loci. The basidiocarp consists of branched flabellae with spore baring hymenium on both sides (5). S. crispa contains a monomitic hyphal system and is a clamp connection producing species (3). Basidiospores are hyaline, smooth, subglobase with thin walls (5). Basidia contain 2-4 sterigmata and basidiospore are generally larger with a low number of spores produced on a single basidium (5).
