Ramaria flava
Description
Ramaria flava is rare a yellow coral mushroom found widely in Europe. Also known by its local name changle it is also native to temperate areas of southern Chile and south of Brazil (state of Rio Grande do Sul). The outer shape of this mushroom looks a bit like cauliflower. There are two main parts of this type of mushrooms - the body and the small branches. The body is thick, fragile and usually has a yellowish-white color. The branches usually have a bright yellow color and are densely packed when young. When older, they are a bit more distanced. The branches mostly stand upright and are soft and fragile. The spore of this species is dark yellow, sometimes with a tone of brown coloration.
Ramaria flava is reported to be edible (after 15 minutes of boiling, boiled, fried) but of only moderate quality. However, it could easily be confused with Ramaria formosa, which is mildly poisonous, causing stomach pains and diarrhea if eaten.
Common names: Changle, Dzeltenā korallene (Latvia).
Mushroom Identification
Fruitbody
When fully developed the whole fruitbody is usually 6 to 20 cm tall, and up to 15 cm across. Lemon-yellow to sulfur-yellow coral with many dense branches; the short stalk is 5-8 cm long and 4-5 cm across. The tips of the terminal branches bruise reddish; they are usually either blunt or have two or three points. When old this coral turns ochre progressing from the tips downwards.
Spores
Ramaria flava var. flava has oblong-ellipsoidal to subfusiform spores, 11-18 x 4-6.5µm, with a rough surface; inamyloid. Ramaria flava var. parvispora has similar spores (shown here) but much smaller at 7-10 x 3.5-5µm.

History
This coral fungus was described in 1763 by German naturalist Jacob Christian Schaeffer, who gave it the scientific name Clavaria flava. It was French mycologist Lucien Quélet who, in 1888, redescribed this species under its currently-accepted scientific name Ramaria flava.
Synonyms of Ramaria flava include Clavaria flava Schaeff., Coralloides flavus Tourn. ex Battarra, and Corallium flavum (Schaeff.) G.Hahn.
Ramaria, the generic name, comes from Ram- meaning branch, with the suffix -aria meaning possessing or furnished with. Ramaria coral species are indeed furnished with numerous branches.
The specific epithet flava means yellow.
