Branched Corals
White Coral Fungus (Clavulina coralloides)
Notes: syn. Clavulina cristata
Habitat & Ecology: mycorrhizal; on the ground, on humus; coniferous or mixed forest; summer and fall
Branches: repeatedly branched, form is variable, sometimes with very irregular branching and sometimes unbranched
Tips: “cristate” – feathery or toothed; flattened near apex
Texture & color: smooth or knobby surface; white, cream, or pinkish tan; flesh white and fragile
Stem or base: stem smooth and gray/black when parasitized by Helminthoshaeria clavarium
Flesh: odor not distinctive
Spore print: white
Look-alikes: This species is often parasitized by a fungus that turns it grey-black, attacking from the bottom up. This can make it look like the Grey Coral (C. cinerea). The distinction can be made if the grey coloring is lighter near the base than the branches.
Grey Coral Fungus (Clavulina cinerea)
Notes:
Habitat & Ecology: mycorrhizal; on the ground; coniferous or mixed forest; summer and fall
Branches: repeatedly branched, irregular, looking tangled
Tips: pointed or blunt, often forked
Texture & color: smooth; ash-grey maybe tinted purple; flesh white and fragile
Stem or base: fleshy trunk if present
Flesh: odor not distinctive
Spore print: white
Look-alikes: White Coral Fungus (Clavulina coralloides) is whiter unless it is parasitized by Helminthoshaeria clavarium, a fungus that turns it grey-black, attacking from the bottom up.

Branches: repeatedly branched and cylindrical
Tips: crown or cup-shaped tips (4-8 of them)
Texture & color: smooth; off-white, turning brown with age; flesh white and tough
Stem or base: colored as branches and with fine hairs
Flesh: odor smells faintly of raw potatoes
Spore print: white
Look-alikes:
Ramariopsis kunzei
Notes:
Habitat & Ecology: saprophytic; on the ground on buried wood or well-decayed logs; summer and fall
Branches: profusely branched
Tips: blunt tips
Texture & color: smooth surface; white and turning pink-tan with age; flesh white and fragile
Stem or base: inconspicuous stem, finely fuzzy when present and becoming pink-yellow
Smell: not distinctive
Spore print: white
Look-alikes: Lacks the cup-shaped tips of the Crown-tipped Coral (Artomyces pyxidatus) and the feathery tips of White Coral Fungus (Clavulina coralloides).
See.. Jellied False Coral (Tremellodendron schweinitzii) which is chalky and does not have as defined branches that reach up like true corals.
See Helminthosphaeria clavarianum parasitic fungi that use White Coral Fungus (Clavulina coralloides) as a host.
Violet Coral Fungus (Clavaria zollingeri)

Texture & color: smooth; purple; flesh purple and fragile
Stem or base:
Smell: maybe radishlike
Spore print: white
Look-alikes: Clavulina amethystina is a European species; Clavulina amethystinoides is a more muted purple, less branched, and with a bumpy surface; Alloclavaria purpurea is a dull purple, unbranched, clustered and in coniferous forests.
Ramaria spp.
Notes: East Coast and Midwest species are undescribed – Ramaria spp. are indicators of highly ecologically valued forests
Habitat & Ecology: uncertain if mycorrhizal or saprophytic; on coniferous or sometimes deciduous wood, but may be buried, appearing to come out of the ground; early summer and fall
Branches: branches vertically straight and parallel; compact and sometimes branched
Tips: tips fine and yellow
Texture & color: yellow buff; white flesh, bruising purplish, brown when held
Stem or base: poorly developed, fleshy stalk connected to white rhizomorphs (thick mycelial cords)
Smell: sweetish
Spore print: rusty yellow
Chemical reactions (via Mushroomexpert.com): Iron salts green on branches
Look-alikes:
See Hen of the Woods or Maitake (Grifola frondosa) which is a bracket fungi that grows at the base of oak trees and has a coral-like arrangement.
