Description:RAMARIA CLAVIRAMULATA Marr and Stuntz. Biblioth. Mycol. 38: 63. 1973. Fig. 15
HOLOTYPE: SUCO-Washington, Lewis Co., Goldmeyer Hot Springs Trail, approximately 9 mi east of North Bend, 4.x.66, Marr. no. 392 [!].
Fruitbodies 5-9 x 3.5-4.5 cm, ovate to obovate in outline. Stipe single to fasciculate, 1.4 x 0.5-2 cm, moderately rounded to tapered, slender, creµm colored to brownish white, strongly rubri-brunnescent, sometimes in subareolate regions of darker brown, without abortive branchlets; flesh ivory-colored to tan, homogeneous, moist but not slippery or gelatinous. Major branches several, not terete, ascending, not curved, superficially rugulose. Branches in 4-6 ranks, pastel salmon-ochre ("ochraceous buff" with salmon hint) to greyish orange (5B4-5), of two types: 1) more or less terete, dichotomous, up to 4 mm thick; internodes long, up to 3 cm below, diminishing gradually at maturity; and 2) inflated up to 13 mm thick, rugulose; flesh soft, punky; axils rounded. Apices cusped to antleror molar-like on inflated branches, rich yellow ("antimony yellow") when young, concolorous with branches in age. Odor musty, krauty, medicinal; taste bitter.
Macrochemical reactions: FSW = stipe flesh instantly deep green; KOH = oxide red (8E8) to orange; IKI = branch sections sometimes weakly positive; PYR, PHN, ANW, ANO, GUA = negative.
Tramal hyphae of stipe 5-23 µm diam, hyaline, thick-walled (wall 1-5 µm thick), clampless,
tightly interwoven; ampulliform inflations up to 12 µm broad, thick-walled, with sparse stalactitiform ornamentation; gloeoplerous hyphae not observed. Tramal hyphae of upper branches 330 µm diam, hyaline, clampless, thin- to thickwalled (wall up to 1 µm thick), loosely parallel inward, strictly so outward; hyphal anastomoses occasional; ampulliform inflations and gloeoplerous hyphae not observed. Subhymenium thick; hyphae 5-8 µm diam, lattice-like, clampless, thin-walled. Hymenium thickening; basidia 50-60 x 8-9 µm, clavate, clampless; contents homogeneous when young, with scattered minute guttules at maturity, weakly cyanophilous; sterigmata 4, straight, slender.
Spores (Fig. 5) 8.6-11.9 x 4.3-6.1 µm (E = 1.60-2.20; Em = 1.89; Lm = 10.03 µm), cylindrical to ellipsoid, flattened adaxially, smooth to very obscurely undulate in profile; contents yellow to ochre, refringent, aguttulate to uniguttulate, the guttule deep ochraceous; wall up to 0.3 µm thick; hilar appendix very prominent, conical, appearing thick-walled under phase contrast; ornamentation of very low, lobed, meandering ridges and a few isolated warts longitudinally oriented.
Commentary. -Spore ornamentation is unusual for this subgenus. Viewed in optical section under phase contrast, most spores appear smooth, with some subtly undulate. When stained in an-
iline blue, however, no unornamented spores were observed. All spores showed longitudinally arranged low ridges, appearing as though paint had been dropped on the spore apex and had dripped down the length of the spore wall.
The entire spore is refringent under phase contrast, unlike those of most Ramaria taxa, in which the guttule(s) may be refringent, but the cytoplasm hardly so. Moreover, the hilar appendix appears glassy under both phase contrast and bright field microscopy, as though constructed of solid wall material. Large-spored members of subg. Echinoramaria (i.e., R. guayanensis (Pat.) Corner, R. pancaribbea Petersen, etc.) often exhibit this construction, but I know of no other representative in subg. Laeticolora with such spore morphology.
Stipe tramal hyphae are extremely thick-walled, but do not shatter in squash mounts. Stipe flesh is moderately hard when dry, but not brittle or cartilaginous.
The type specimen and its accompanying diapositive clearly show that some branches inflate much more than others. One fruitbody appears to have about half the branches very slightly inflated, but the other half are grossly enlarged. Such pistillariform inflations resembles those found in R. obtusissima (Peck) Corner, but other taxa show the phenomenon, usually in aged fruitbodies. Indeed, from the description by Marr and Stuntz (1973) and Marr's diapositive, I conclude that both type fruitbodies are mature or overmature, supported also by the greatly thickened hymenium, embedded spores, and extensive subhymenium.
The phenomenon of branch inflation, rather than being caused merely by age, may be a pathological condition. Such a conclusion might be supported by the inflation of portions of the branch system, but not all. This selectivity seems not to be random, but confined to areas within angles of radii as seen from above. The condition may be similar to that found in Entoloma abortiva (B. & C.) Donk, where the whole fruitbody or only portions may be involved in the teratological monstrosity.
Only one specimen was cited by Marr and Stuntz (1973, the holotype), so their description can be taken also as a type specimen study. One additional collection has been gathered in northern California. Fruitbodies agreed with the type in stature, general color, microscopic characters and macrochemical reactions (except branch sec
tions in IKI). A few branches of one fruitbody were inflated but retained more or less normal apices.
