Taxonomy
First described in 1821 by Swedish mycologist Elias Magnus Fries, it has since acquired an extensive synonymy of alternate scientific names.[2] Until 2014, it was the sole member of the Climacocystis,[3] a genus circumscribed by Czech mycologists František Kotlaba and Zdeněk Pouzar in 1958,[4] when the newly described Chinese species Climacocystis montana was added to the genus.[5]
Description
Climacocystis borealis is both a saprophyte and a secondary pathogen that causes a heart rot in the roots and bole of host trees.[6]
The fruiting bodies attach directly to the wood, usually in single brackets but sometimes joined. The caps are whitish to yellowish, 5–15 centimetres (2–6 in) wide and 2–5 cm (3⁄4–2 in) thick, with no stipe. The whitish flesh is juicy closer to the margins. The spore print is white.[7]
Similar species
Many Polyporales genera include similar polypores, typically smaller than those of Climacocystis. Similar species include Postia tephroleuca, Spongipellis delectans, S. delectans, and Tyromyces chioneus.[7]
