Contents

Hyphodontia sambuci, or elder whitewash, is a basidiomycete fungal pathogen on deadwood, especially elder. [1]

It is resupinate, forming a very thin structure which is white, pruinose (flour-like dusting) or chalky in appearance. It is inedible. [1] It also grows on dead but still hanging branches of Fraxinus , Berberis , Nothofagus , Ulmus , Populus , Hedera , Ribes , Symphoricarpos and rarely on conifers such as Cryptomeria . [2]

Ecology

As stated, H. sambuci occurs in North Europe mostly on Sambucus nigra , but there is a much bigger spectrum of substrates in warmer regions in southern areas. The variability of micromorphology increases in the tropics, but the macromorphological characteristics however always stay the same: the basidiocarp with chalky white color and often growing as aerophyte on dead branches of trees and bushes, that are still attached to the tree. H. sambuci consists of a complex of species. Similar species with capitate cystidia; thin-walled hyphae and exactly the same chalky white fruit body are H. griselinae and H. fimbriata. They can be differentiated by their spores and morphology of their basidiocarp. [2]

<i>Heterobasidion annosum</i> Species of fungus

Heterobasidion annosum is a basidiomycete fungus in the family Bondarzewiaceae. It is considered to be the most economically important forest pathogen in the Northern Hemisphere. Heterobasidion annosum is widespread in forests in the United States and is responsible for the loss of one billion U.S. dollars annually. This fungus has been known by many different names. First described by Fries in 1821, it was known by the name Polyporus annosum. Later, it was found to be linked to conifer disease by Robert Hartig in 1874, and was renamed Fomes annosus by H. Karsten. Its current name of Heterobasidion annosum was given by Brefeld in 1888. Heterobasidion annosum causes one of the most destructive diseases of conifers. The disease caused by the fungus is named annosus root rot.

<i>Trametes elegans</i> Species of fungus

Trametes elegans, also known as Lenzites elegans and Daedalea elegans, is a common polypore and wood-decay fungus with a pantropical distribution found on hardwood hosts in regions including Australia, New Zealand, and Japan. It has recently been suggested to be a complex of three different species: T. elegans,T. aesculi, and T. repanda.

<i>Meripilus giganteus</i> Species of fungus

Meripilus giganteus is a polypore fungus in the family Meripilaceae. It causes a white rot in various types of broadleaved trees, particularly beech (Fagus), but also Abies, Picea, Pinus, Quercus and Ulmus species. This bracket fungus, commonly known as the giant polypore or black-staining polypore, is often found in large clumps at the base of trees, although fruiting bodies are sometimes found some distance away from the trunk, parasitizing the roots. M. giganteus has a circumboreal distribution in the northern Hemisphere, and is widely distributed in Europe. In the field, it is recognizable by the large, multi-capped fruiting body, as well as its pore surface that quickly darkens black when bruised or injured.

<span class="mw-page-title-main">Botryobasidiaceae</span> Family of fungi

The Botryobasidiaceae are a family of fungi in the order Cantharellales. The family contains a group of corticioid fungi that form thin, web-like basidiocarps. Some species form asexual anamorphs producing chlamydospores. All are believed to be wood-rotting or litter-rotting saprotrophs. None is known to be of any economic importance.

<span class="mw-page-title-main">Corticioid fungi</span> Group of fungi

The corticioid fungi are a group of fungi in the Basidiomycota typically having effused, smooth basidiocarps that are formed on the undersides of dead tree trunks or branches. They are sometimes colloquially called crust fungi or patch fungi. Originally such fungi were referred to the genus Corticium and subsequently to the family Corticiaceae, but it is now known that all corticioid species are not necessarily closely related. The fact that they look similar is an example of convergent evolution. Since they are often studied as a group, it is convenient to retain the informal (non-taxonomic) name of "corticioid fungi" and this term is frequently used in research papers and other texts.

<span class="mw-page-title-main">Clavarioid fungi</span> Group of fungi

The clavarioid fungi are a group of fungi in the Basidiomycota typically having erect, simple or branched basidiocarps that are formed on the ground, on decaying vegetation, or on dead wood. They are colloquially called club fungi and coral fungi.

<i>Armillaria</i> root rot Fungal tree disease

Armillaria root rot is a fungal root rot caused by several different members of the genus Armillaria. The symptoms are variable depending on the host infected, ranging from stunted leaves to chlorotic needles and dieback of twigs and branches. However, all infected hosts display symptoms characteristic of being infected by a white rotting fungus. The most effective ways of management focus on limiting the spread of the fungus, planting resistant species, and removing infected material. This disease poses a threat to the lumber industry as well as affecting recreational areas.

<i>Calocera viscosa</i> Species of fungus

Calocera viscosa is a species of fungus in the family Dacrymycetaceae. In the UK, it has the recommended English name of yellow stagshorn. In North America it is variously called coral jelly fungus, jelly staghorn, yellow false coral, yellow tuning fork, and jelly antler. Basidiocarps are gelatinous, bright golden yellow, and branched. It grows exclusively on logs and dead wood of conifers. Calocera viscosa is a common species throughout Europe and has also been recorded from North America, Asia, and Australia.

<i>Heterobasidion irregulare</i> Species of fungus

Heterobasidion irregulare is a tree root rotting pathogenic fungus that belongs to the genus Heterobasidion, which includes important pathogens of conifers and other woody plants. It has a wide host and geographic range throughout North America and causes considerable economic damage in pine plantations in the United States. This fungus is also a serious worry in eastern Canada. Heterobasidion irregulare has been introduced to Italy (Lazio)(modifica) where it has been responsible for extensive tree mortality of stone pine. Due to the ecology, disease type, host range/preference, interfertility group, and genetic information, H. irregulare was designated a new species and distinguished from Heterobasidion occidentale.

<i>Serpula himantioides</i> Species of fungus

Serpula himantioides is a species of fungus that causes damage to timber referred to as dry rot. It is a basidiomycete in the order Boletales. It has been found on all continents except for Antarctica. Recent molecular work demonstrates that S. himantioides is a species complex including multiple cryptic lineages.

<i>Heterobasidion occidentale</i> Species of fungus

Heterobasidion occidentale is a tree root-rotting pathogenic fungus in the family Bondarzewiaceae. It is endemic in western North America west of the Rocky Mountains from Alaska to southern Mexico. While a natural agent of forest turnover, H. occidentale has become of increased concern due to forest management processes such as pre-commercial thinning, altered site density and species composition, and carbon sequestration. H. occidentale forms part of the genus that includes other species forming the important forest pest Heterobasidion annosumsensu lato that is spread across the Northern Hemisphere. H. occidentale is part of the S-type intersterility group differing from the other North American species, Heterobasidion irregulare.
