Description:RAMARIA INSIGNE (Pat.) Petersen, comb. nov.
Basionym: Lachnocladium insigne Patouillard. 1889. Jour. Bot. 3: 34, pl. l, Fig. 2.
Type (holotype): FH - Guyane [Francais] (Maroni), no date, Melinon no. 104 [!]; merotype fragment, NCU [!].
Pl. 1, Fig. 9; text Figs. 19-21.
Fruitbodies (Fig. 19, 20) up to 15 cm high, up to 6 cm broad, repeatedly and usually dichotomously branched, all parts very slender. Stipe up to 70 x 3 mm (teste Patouillard: on type specimen 25 x 3 mm), very slender, curved (on type), naked to smooth but not glabrous, whitish where protected, brown above. Branches never more than 3 mm thick (usually not more than 2 mm), repeatedly rebranching dichotomously, clear brown (teste Patouillard), blackish when dried; axils lunate, deeply decurrent; apices prolonged, up to 1.5 cm, very slender, ascending; hymenium clearly unilateral, the fertile, outer surface smooth, clear brown, waxy, the inner, sterile surface furfuraceous to plushy, rusty brown from spores; branch fragments (dry) almost black in dilute EOH solution.
On moist soil and/or lignous duff; tropical South and Central America, Caribbean islands.
Tramal hyphae of branches agglutinated, yellow in mass, clamped, thin-walled, tightly parallel. Basidia hardly measurable, golden-refringent, 2-sterigmate; sterigmata stout, conical, divergent.
Spores (Fig. 21) 9.6-10.7 x 6.3-7.4 µm (E = 1.35-1.53;
Em = 1.43; _Lm = 10.1 µm), broadly ellipsoid to short cylindrical; contents homogeneous (in age?) to obscurely uniguttulate; wall up to 0.7 µm thick; hilar appendix prominent, eccentric, conical-papillate, leaving no "throat"; ornamentation of share, tapering, conical, spines up to 1.5 µm long, usually randomly placed but sometimes in suggestions of spiraling rows.
Macrochemical reactions: not recorded.
OBSERVATIONS: This seems very close to R. guyanensis, fron vhich it differs in larger spores and larger fruitbodies. SEM , iotos of spores of R. guyanensis (pl. 8, Figs. 3, 4) and
R. ir, igne (pl. 1, Fig. 9; pl. 2, Fig. 6) show the spines of the l,itter to be much sharper and more discrete than those of R. guyanensis. Unfortunately, both taxa are known only from a few specimens, so their relative maturity cannot be judged. Together, however, they are a compact group, easily denoted by their very slender parts, including the stipe which hardly appears to be able to hold up the fruitbody.
Patouillard (ibid.) indicated that the fruitbody of R. insigne arose "d'un tubercule ligneux subglobuleux." There is no sign of a sclerotium in the type specimen, and to what structure he referred is unknown to me. One specimen (herb. Montagne, DC) shows a thickened mycelial felt at the base of the stipe, which might account for Patouillard's notion, although the specimen is labeled as Clavaria tubulosa Fr. (q.v. sub. nomina dubia).
Corner's (1950: 568) placement of the name under R. cyanocephala may have been encouraged by the slender stature, but the characteristic coloration of the apices has never been attributed to R. insigne, and the type bears little resemblance to R. cyanocephala.
