Clavicorona pyxidata var. pyxidata (Pers.) Doty: 43 (1947)
One of the most common coral fungi. The presence of clearly expressed "little crowns" at the tip of each branch allows with complete confidence to distinguish Clavicorona pyxidata from other common fungi of similar shape.
Short, light-colored.
2–16 cm in height. Coral-like, bushy, branched form (the fungus "branches vertically" from a common base, on a whitish or brownish mycelial network). Each "branch" is crowned with a kind of "crown" or "little cup". The coloration of fruiting bodies is initially light yellow, then the upper branchlets fade to pale yellow, and closer to the base fade to yellowish-brown; with age, they become entirely brownish.
Tough, elastic, yellowish, with a neutral or mildly peppery taste.
Weak, earthy.
Spore print white. Spores amyloid, finely spiny.
Occurs in groups, both under the forest canopy and in well sun-warmed places (on rotten logs at forest edges). Can be found on leaf litter (including coniferous) and small twigs. Widespread throughout.
There are no truly similar species; it may be mistaken for other forms of coral fungi at young or old stages.
From the liquid culture of this fungus, the sesquiterpene compounds pyxidatols A-C, tsuikolin E, and omphadiol have been obtained.
