Species Information
Summary:
Features of Ramaria rubiginosa include 1) medium size, 2) thick, single or somewhat compound stem, 3) branches that are light yellow with bright yellow tips, 4) any part of the fruitbody but especially the base bruising or staining ''reddish brown'', 5) spores finely ornamented with lobed anastomosing warts, and 6) absent clamp connections. It is possible that this is the same species as Ramaria sanguinea (Pers.) Quel., in which case Ramaria rubiginosa would be reduced to a synonym of that species (Petersen(12)). The average spore length divided by the average spore width is 2.14: there is apparently an unnamed species that is similar but with average spore length divided by average spore width = 2.50, (M. Beug, pers. comm.).
Chemical Reactions:
stem flesh inamyloid or very faintly amyloid, (Marr), while the hymenial surface of all Ramarias turn blue-green in FSW, the reaction of the hymenial surface of Ramaria rubiginosa was unusually fast and intense, however the reaction of the stem context is actually only slowly positive to FSW: the strong reaction as recorded in Marr(1) is an error (M. Beug, pers. comm.)
Odor:
not distinctive or faintly sweet, (Marr)
Taste:
not distinctive (Marr)
Microscopic:
spores 7-11 x 3.5-6 microns, average 9.4 x 4.4 microns, cylindric, finely ornamented with lobed, anastomosing warts, these faintly more cyanophilic than the general wall; basidia mostly 4-spored, 42-85 x 7-11 microns, clavate, clampless, inclusions cyanophilic; clamp connections absent, (Marr)
Spore Deposit:
grayish yellow'' (Marr)
Notes:
Ramaria rubiginosa is found at least in WA (Marr). There are collections from OR at Oregon State University. There is a collection from BC by O. Ceska at the University of British Columbia.
EDIBILITY
probably edible (Scates-Barnhart)
Habitat and Range
SIMILAR SPECIES
Ramaria cystidiophora var. maculans has a less stout fruitbody, less conspicuous stains, clamped hyphae, and acantho-dendroid gloeoplerous hyphae in the stem, (Marr). Pacific Northwest species reacting with ferric sulphate 10% aqueous solution in the stem base include Ramaria testaceoflava (clamped basidia, average spore length 11.8 microns), Ramaria amyloidea (clamped basidia, average spore length 8.9 microns, stem flesh amyloid), Ramaria velocimutans (clamped basidia, average spore length 9.0 microns, stem flesh inamyloid), R. rubiginosa (clampless basidia, no rusty root), Ramaria celerivirescens (clampless basidia, rusty root, normal terminal branches), and Ramaria claviramulata (clampless basidia, rusty root, chubby terminal branches, branches turn reddish brown with 20% KOH), (Exeter(2)). Ramaria vinosimaculans, Ramaria maculatipes, and Ramaria cystidiophora var. maculans are other taxa that characteristically develop reddish brown stains, (Marr). Ramaria synaptopoda also has a yellow fruitbody and reddish brown stains on the lower part of the fruitbody, but has a pronounced fasciculate [bundled] habit. Ramaria rubribrunnescens also develops reddish brown stains.Habitat
terrestrial, growing under Tsuga heterophylla (Western Hemlock), October and November, (Marr)
