# Largest fungal fruit bodies

The largest mushrooms and conks are the largest known individual fruit bodies. These are known as sporocarps, or, more specifically, basidiocarps and ascocarps for the Basidiomycota and Ascomycota respectively. These fruit bodies have a wide variety of morphologies, ranging from the typical mushroom shape, to brackets (conks), puffballs, cup fungi, stinkhorns, crusts and corals. Many species of fungi, including yeasts, moulds and the fungal component of lichens, do not form fruit bodies in this sense, but can form visible presences such as cankers. Individual fruit bodies need not be individual biological organisms, and extremely large single organisms can be made up of a great many fruit bodies connected by networks of mycelia (including the "humongous fungus", a single specimen of Armillaria solidipes) can cover a very large area.
The largest identified fungal fruit body in the world is a specimen of Phellinus ellipsoideus (formerly Fomitiporia ellipsoidea). The species was discovered in 2008 by Bao-Kai Cui and Yu-Cheng Dai in Fujian Province, China. In 2011, the two of them published details of extremely large fruit body of the species that they had found on Hainan Island. The specimen, which was 20 years old, was estimated to weigh between 400 and 500 kilograms (880 and 1,100 lb). This was markedly larger than the previously largest recorded fungal fruit body, a specimen of Rigidoporus ulmarius found in the United Kingdom that had a circumference of 425 cm (167 in).

Ellsworth Call was 1.63 m (5 ft 4 in) wide by 1.37 m (4 ft 6 in) broad by 24 cm (9.4 in) high.

| Chaga mushroom Inonotus obliquus Polyporaceae | Much of the Northern Hemisphere. This one in Quebec. | Circumference of 42 inches (110 centimeters). | | 78.2 pounds (35.5 kilograms). | Approximately 15 additional pounds (6.8 kilograms) was left on the host tree for regrowth, bringing the total weight to around 93 pounds (42 kg). |
| Phlebopus marginatus, Boletaceae | Native to humid regions of Australia, New Zealand, Sri Lanka, Sumatra and Java. | One found in South Australia prior to 1934 had a cap (pilea) 61 cm (24 in) wide by 46 cm (18 in) broad. | | Same one (?) weighed 32.34 kg (71.3 lb) | Another, at Hall's Gap, Victoria in 1939 weighed 28.6 kg (63 lb) but was 77.5 cm (30.5 in) across the cap. The broadest specimen in recent years was one found on the farm of Mary Phillips at an unspecified location in Australia. Assuming her hand to measure 3 in (76 mm) across the knuckles, the cap is 25 in (640 mm) wide across its longest axis. The most massive (heaviest) in recent years may be one discovered by Pamela McIntyre of Digby, Victoria in July 2012, which was found to weigh forty-four pounds (twenty kilograms). Called the "Giant Toadstool" in eastern Australia, and "Salmon Gum Mushroom" in Western Australia. Much of the literature is under the older name Boletus portentosus. |
| Ganoderma lucidum, Ganodermataceae | China. This one Guangxi Province. | Cap 107 cm (42 in) wide. Stem short; only ±7 cm (±3 in ) thick. | | By one report 14.9 kg (33 lb) but by another 7.45 kg (16.4 lb). | Fruiting body of G. lucidum can be a conk or a mushroom, depending on the orientation of the substrate. |
| Sparassis crispa, Sparassidaceae | The mountains of Europe, always in pine forest. | One found in Mayres, France in October 2000. Dimensions not stated. | | 28.8 kg (63 lb). | The Clavariaceae do not form caps. The spores are produced on stalagmite-like growths. |

| Meripilus giganteus, Polyporaceae | Europe | Up to three feet (0.91 meters) wide, usually accompanied by smaller ones. | | | |

Another in Costa Rica measured 1 m (3 ft 3 in) in width. | 68.8 cm (27.1 in) in height. | The Chiapas specimen weighed 20 kg (44 lb). | This species was only discovered in 1980 (originally named Tricholoma titans). It was apparently not known to native peoples. That such a conspicuous and widespread species escaped notice for centuries constitutes a major anomaly. |
| Macrocybe gigantea (formerly Tricholoma giganteum), Tricholomataceae | Native to China, India, Pakistan, and Nepal. | A cluster of 5 or 6 joined at the base was found in Tengchong County, Yünnan Province, China in 2017.

| Buglossoporus magnus, Fomitopsidaceae | Apparently endemic to the Malay Peninsula. | In 1940 Prof. E.J.H.

The measurements were certified by the Iowa Department of Natural Resources. | 37 cm (15 in) in height | It weighed 1.5 pounds (680 grams) | |

## Unidentified specimens

Two large specimens are excluded from the list above. The first, a polypore photographed in 1903 at Yeerongpilly, Brisbane, Queensland, measured about 2 m (6 ft 7 in) in width by 1 m (3 ft 3 in) top to bottom, emerging from a tree about two 2 m (6 ft 7 in) thick. It was sturdy enough to support the weight of two average women.
The second is more speculative. Somewhere in his world travels, writer/naturalist/explorer Ivan T. Sanderson encountered reports of a species of fungi which "weigh a ton, and upheave large trees". The earliest report appears to have been in the writings of James Brooke.
