Sarcosoma spp. description

KingdomFungi
PhylumAscomycota
ClassLecanoromycetes
OrderPezizales
FamilySarcosomataceae (1)
GenusSarcosoma

Sarcosoma globosum is a fungus that produces large, cup-shaped fruiting bodies. These barrels are dark brown to black in colour (2); the stipe (or stem) is wrinkled, whilst the inside of the cup has a jelly-like texture (3).

WARNING: many species of fungus are poisonous or contain chemicals that can cause sickness. Never pick and eat any species of fungus that you cannot positively recognise or are unsure about. Some species are deadly poisonous and can cause death within a few hours if swallowed.

Sarcosoma spp. biology

The highly distinctive, barrel-shaped fruiting bodies are found between early spring and early summer (4).

Fungi are an enormous group of organisms that are so distinctive from both plants and animals that they are placed in their own kingdom. The main body of the fungus is composed of a multitude of microscopic threads (known as ‘hyphae’) which are located within the substrate (5). The fruiting body (such as the more familiar mushroom or toadstool) is produced to release spores and thus allows reproduction to occur. Fungi feed by absorbing nutrients from their surroundings.
