Ramaria stricta

Ramaria stricta, commonly known as the strict-branch coral is a coral fungus of the genus Ramaria. It has a cosmopolitan distribution, and grows on dead wood, stumps, trunks, and branches of both deciduous and coniferous trees. Its fruit body is up to 10 cm (3.9 in) tall, made of multiple slender, compact, and vertical parallel branches. Its color is typically light tan to vinaceous-brown. All parts of the mushroom will bruise when handled. There are several lookalike corals that can usually be distinguished from R. stricta by differences in coloration, bruising reaction, or microscopic features. The fungus is inedible due to its unpleasant odor and bitter taste.

Taxonomy

The species was originally described under the name Clavaria stricta by Christian Hendrik Persoon in 1795.[2] In 1888, French mycologist Lucien Quélet transferred the species to the genus Ramaria.[3]

It is commonly known as the "upright coral".[4]

Description

The color of the fruit body is light yellow brown to paler toward extremities, the tips are light yellow; bruising light reddish brown. The basidiocarp has a leathery texture when fresh, but becomes brittle when dry. The stipe is branched up to 8 times, and the branches are all upright and nearly parallel. The branches ending in 4 to 5 thornlike tips.[5] Overall, the fruit body appears bushy, and is medium-sized, up to 10 by 7 cm (3.9 by 2.8 in). The stipe is single or branching from the base; with white mycelium and rhizomorphs radiating from the base. The odor is of anise. The taste is bitter.[6] The fruit bodies have been described as "edible but unpalatable,"[7] although other guides say the species is inedible.[8]

The spore print is dark yellow. Spores are roughly elliptical, dotted with low cyanophilous warts, and measure 7–10 by 3.5–5.5 μm. The basidia have basal clamps are mostly four-spored, and sometimes have cyanophilous granular contents.[6]

Variants

Several variants have been described:

var. alba
var. concolor
var. fumida
var. violaceo-tincta

Similar species

Another widespread and common coral, R. apiculata, typically grows on conifer wood, and bruises brown like R. stricta, but it has green pigmentation.[7] R. apiculata is a dull buff-tan to dull orange-brown, and young fruit bodies often have white branch tips.[9] R. gracilis prefers conifer wood, and has lighter colors than R. stricta. The tropical R. moelleriana can only be reliably distinguished from R. sticta by location and microscopic characteristics.[4] R. flava is mycorrhizal, and grows under coniferous and deciduous trees. Its fruit bodies are typically taller, have a more unpleasant odor, and a less bitter taste.[10]

Distribution and habitat

Ramaria stricta has a cosmopolitan distribution,[5] and is a fairly common species. The fungus is lignicolous, common in late summer and fall in coniferous forests of the Pacific Coast and Rocky Mountains.[7] The fungus grows on dead wood, stumps, trunks, and branches of both leafy and coniferous trees.[11] The form that grows on deciduous wood tends to be more orange and less bushy than those which grow on coniferous wood. Fruit bodies can form in "log lines" where decaying wood is buried underground near the surface, or is in an advanced state of decomposition.[9]

gollark: Sure.
gollark: umnikos said> and a very good argument for uniting the european union more stronglywhich I disagree with.
gollark: You seem to be missing what I'm talking about here.
gollark: If your large group makes about the same quality of decision, it might not.
gollark: If your large group can make better decisions than the smaller ones, it probably makes sense.
