History and taxonomy

edit

This fungus was first described by Jakob Friedrich Ehrhart in 1787.[4][5]

Habitat and ecology

edit

Throughout North America[1] and Europe[5] Thelephora terrestris can be found in soil. It is commonly found in sandy soils under pine trees, on roots[1] and twigs.[6]

This ectomycorrhizal fungus forms a symbiotic relationship known as mycorrhizae, especially with Pinus species.[7] It is commonly found in pine forests[8] as well as plant nursery soils world wide.[9] This fungus is known to get water and nutrients from far away[10] and being capable of growing in both low fertility and high fertility soils.[2]

It is a dominant mycorrhizal fungus,[9] re-establishes quickly after disturbances such as forest fire, and is considered stress tolerant.[11]

Outside of the Pinus genus, it is also capable of forming mycorrizha with other trees such as alder, birch, oak, beech, and poplar.[2]

Thelephora terrestris virus 1 (TtV1), which is a mycovirus, can infect this fungus.[2]

Description

edit

Thelephora terrestris is present year round, though is mostly seen July to December.[1] As the fruiting body forms, it starts off lighter in colour then turns to a darker shade of brown as it ages.[7] A stalk may not be present, if there is one, it is usually very short.[1] Sometimes the fungus is grown in large colonies.[6] The shape is described as a fan and can grow up to 6 cm wide.[6] It has been described to have a moldy earth like smell.[1]

Thelephora terrestris
 Smooth hymenium
 No distinct cap
 Hymenium attachment is not applicable
 Stipe is bare
 
Spore print is purple-brown
 Ecology is mycorrhizal
 Edibility is inedible

The hyphae of mycorrhizal forms walls that becomes thicker as it ages, while in earlier stages may be spiney.[12] When mating, the hyphae forms clamp connections[7] The spores are purple-brown colour,[1] ellipsoid or angular shape.[6]

The edibility of this fungus is unknown, but it is considered too tough to be worthwhile.[13]

Thelephora palmata is a similar species which is comparatively stinky and less widely distributed.[13][14]

Physiology

edit

The full life cycle can be reproduced and studied in a laboratory, both ectomycorrhizal form and mushroom form.[15]

Due to the mycotoxins that the fungi produces, it protects pinus trees from root pathogen Phytophthora cinnamomi.[9]
