Ramaria flavosaponaria is a species of coral fungus in the family Gomphaceae. It is found in the mountains of eastern North America from Georgia and Tennessee to Nova Scotia.[2][3]
Names[]
The specific epithet is from the flavo ('yellow')[4] and saponaria ('soapy'),[5] both of which are distinguishing features of the mushroom.[2] The name was originally published as Ramaria flavo-saponaria, including a hyphen.[2] However, this is considered erroneous by the International Code of Nomenclature for algae, fungi, and plants, so the proper orthography is Ramaria flavosaponaria.[6]
Before being formally described in 1986 by Ron Petersen, the species was labelled in scientific collections under various names.[2] Ramaria aurea sensu mihi was used for its resemblance to the European Ramaria aurea.[2] It was also sometimes labeled Ramaria aquafaba,[2] at least as early as 1969,[7] predating the 2015 coinage of the term aquafaba in an unrelated culinary usage.[8] This term possibly relates to the use of some yellow species of Ramaria (possibly including R. flavosaponaria) to make flavorful broth.[9] cooked R. flavosaponaria has a beany flavor,[2][3] so this 'bean water' (Latin aqua + faba[8]) likely led to the early R. aquafaba name.
Description[]
R. flavosaponaria is easily distinguished from related mushrooms by the brilliant gold color, the large number of aborted branchlets, a surface that feels slippery, a lack of clamp connections, and a complex spore ornamentation.[2] It is sometimes confused with Ramaria aurea, which only grows in Europe.[2] also lacks clamps, has small spores, and aborted branchlets, but is a bright red color and not slippery to the touch.[2] There is also a similar Ramaria species in Nova Scotia that is bronze-colored and also not slippery.[2] Macroscopically closely resembles R. flavosaponaria, but the former produces larger spores, has clamps, and flesh that is more gelatinous than soapy.[3]
R. flavosaponaria has fruiting bodies up to 8 by 12 centimetres (3.1 in × 4.7 in) in size[3] that are broadly obovate to circular in shape and cespitose or scattered.[2] The irregularly shaped stipe grows up to 3 by 1.5 centimetres (1.18 in × 0.59 in) with much aborted branching, giving an appearance like cauliflower.[2][3] The flesh is white to yellow, does not bruise, but has a soapy texture without being gelatinous.[2][3] The above-ground parts are weakly vinescent (turning to a red wine color[10]) around particles of soil.[2][3] The flesh is brittle whether dried or fresh.[2]
The odor of fresh specimens is fabaceous (bean-like), which becomes like fenugreek upon drying.[2][3] The taste is described as moderately fabaceous,[2][3] but it is not known if the species is edible. A Colorado couple suffered gastrointestinal distress and cramps from a mushroom similar to the European R. aurea, but if this was R. flavosaponaria or another species is uncertain.[11]
The species tests positive with pyrogallol.[2][3] It is moderately positive in response to ferric chloride.[2][3] Tincture of guaiac is negative on the branch sections but weakly positive on the surface of the stipe.[2][3] Ammonium hydroxide and potassium hydroxide cause bleaching.[2][3] Testing with melzer's reagent is negative.[3]
The trama hyphae of the upper branches are no bigger than 7 μm in diameter and appear glassy, are hyaline, and lack clamp connections.[2][3] The areas near the septa are inflated up to 15 μm and are ornamented delicately.[2][3] Gloeoplerous hyphae are not present.[3][2] The hymenium is thickening, with clavate basidia that also lack clamp connections.[2][3]
The subcylindrical or narrowly ovate spores are 3.6-5.4 × 7.2-11.2 μm with roughened profiles.[2] The spores have walls up to 0.3 μm thick, with ornamentation of low warts and meandering, reticulate, and complex cyanophilous ridges.[2][3] Spore prints are cinnamon buff.[2][12]
Ecology[]
R. flavosaponaria forms ectomycorrhizal relationships with Fagus sylvatica (European beech).[13] It has been found growing under Tsuga canadensis (eastern hemlock) and Quercus (oak) trees.[2][14]
