Summary: Features of Ramaria leptoformosa include 1) medium size 2) fairly slender fruitbody with slender branches, 3) stem single or more commonly compound and white tinged with yellow or orange, 4) branches light orange to light red with tips deep yellow to orange, 5) spores finely ornamented with linearly lobed cyanophilic warts, and 6) clamp connections.
Chemical Reactions: stem flesh inamyloid (Marr), ferric sulphate in water negative with stem flesh (Exeter)
Odor: not distinctive (Marr)
Taste: not distinctive (Marr)
Microscopic: spores 8-13 x 3-5 microns, average 10.6 x 4.1 microns, subcylindric with a suprahilar depression and slight dorsal convexity, finely ornamented with linearly lobed, cyanophilic warts; basidia 1-4-spored (mostly 4-spored), 41-80 x 8-12 microns, clavate, clamped; hymenium about 70-80 microns thick, subhymenium 25 microns thick; subhymenial hyphae 2-4 microns wide, loosely interwoven, thin-walled, with clamp connections; context hyphae 2-14 microns, non-inflated or slightly inflated, moderately cyanophilous, thin-walled, walls smooth or fluted, ampulliform inflations near septa infrequent, 9-15 microns wide, walls of the swellings nearly smooth in the branches, moderately ornamented in the stem, clamp connections present, closed or open, the clamp cell sometimes enlarged up to 9 microns, gleoplerous hyphae present, 3-3.5 microns wide except in localized bulbous regions, (Marr)
Spore Deposit: golden yellow'' (Marr)
Notes: Ramaria leptoformosa has been found at least in WA (Marr). There are collections from OR at Oregon State University. There is a collection from BC at the University of British Columbia (illustrated on Mushroom Observer) and determined by O Ceska.
Habitat and Range
SIMILAR SPECIES
Ramaria formosa has a bruising reaction and less slender habit, average spore width is 5.4 microns, and it typically has cyanogranular protoplasm, (Marr). Ramaria amyloidea, Ramaria maculatipes, and Ramaria rubricarnata might possibly be mistaken for this species but are amyloid positive, (Marr). Ramaria sandaracina var. euosma might possibly be mistaken for this species, but has smaller spores and a subgelatinous consistency (Marr). See also SIMILAR section of Ramaria rubricarnata var. rubricarnata.
Habitat
terrestrial, growing under Pseudotsuga menziesii (Douglas-fir), Taxus brevifolia (Western Yew), and Tsuga heterophylla (Western Hemlock), October and November, (Marr)
