Species Information
Summary:
{See also Orange Chanterelles Table.} Also listed in Veined Category. This species was described in 2003 from Oregon using molecular methods to differentiate it from other chanterelle species. It is similar to Cantharellus formosus but differs in cap color, tending toward an intensely bright pure yellow cap, as opposed to orange-yellow or brownish yellow for C. formosus, but occasional C. formosus are found with the bright color. Colors of the veined underside are similar, microscopy is not helpful, and the two may grow in the same habitat. The stem of C. cascadensis is only occasionally equal and more often club-shaped or wider in the middle or bulbous, whereas the stem of C. formosus is usually equal or narrowing downward. A possible character is that cracking of the cap flanked by orange-brown discoloration during dry weather in C. cascadensis was not observed in C. formosus. The description is derived from Dunham(1).
Gills:
ridges long and strongly decurrent, close and narrow (to 0.2cm broad), variously forked or anastomosing; light orange-yellow to pale yellow (Kelly & Judd colors)
Stem:
2-4.5cm x 1-2cm at top below fertile veined area, occasionally equal but more often club-shaped to ventricose [wider in middle] or with bulb at base, stem flaring upward and not distinct from cap
Odor:
not distinctive
Taste:
not distinctive
Microscopic spores:
spores 7-13 x 5-8 microns, (average 9.3 x 6.3 microns), elliptic to nearly round, smooth, with variable number of oil droplets; basidia 4-spored to 8-spored, 85-100 x 7-9 microns; hyphae colorless, "thin-walled, wavy to interwoven in both context and trama", 5-12 microns wide, regular and diverse clamp-connections present
Spore deposit:
white to yellowish white (colors from Kelly)
Notes:
Cantharellus cascadensis is found in OR (Dunham(1)), and had been sequenced for WA also (M. Beug, pers. comm.). There is a collection from BC at the University of British Columbia. A collection at Dominion Observatory Hill near Victoria BC has sequencing support (A. Ceska, pers. comm.). It also occurs in CA (Siegel(2)). A photo from Montana is said to resemble this species (M. Beug and D. Winkler, pers. comm.)

Habitat and Range
SIMILAR SPECIES
Cantharellus formosus shows orange-yellow to brownish yellow hues on cap, whereas C. cascadensis tends toward an intensely bright pure yellow cap (while occasional C. formosus were bright yellow, C. cascadensis were not found to be yellowish brown): the exact relations to colors of Kelly, of Munsell, and of Ridgway are given in Dunham(1). C. formosus averages slightly smaller (6.1cm, range 2.5-15cm) than C. cascadensis (8.6cm, range 4-12cm); another observation in C. cascadensis, of cracking of the cap flanked by orange-brown discoloration during dry weather was not observed in C. formosus. The stem of C. formosus is sometimes equal but more often narrows downward, whereas the stem of C. cascadensis is only occasionally equal and more often club-shaped to wider in middle or bulbous. (Dunham) Particularly old or waterlogged fruitbodies of C. cascadensis may show yellow only on the outermost edge and resemble Cantharellus subalbidus, (Dunham). Cantharellus roseocanus has been found only in forests with Sitka spruce or lodgepole pine present. The color differentiation from C. cascadensis is similar to that from C. formosus q.v.Habitat
