Description:Clavaria holmskjoldii Oudemans. 1902. In Beih. bot. Zentbl. II: 525. Clavulinopsis holmskjoldii (Oudem.) Corner. 1950. In Ann. Bot. Mem. I: 373. =Ramariopsis holmskjoldii (Oudem.) R. H. Petersen. 1978. In Mycologia 70: 668.
Lectotype: L - Netherlands, Bergen op Zoom, xi.1900, ad terrain, la Fontijn, L. no. 939.194.701 (annot. C. Cool).
Fruitbodies two, up to 5 x 4 cm, pressed, branched, ramarioid. Stipe 7 x 7 mm, rounded at base, probably white, sulcate, tapering downward. Major branches two, short (-6 mm), stout (-4 mm broad), rebranching in 2-4 ranks; branches probably terete when fresh, dichotomous throughout, white or whitish when fresh (teste Oudemans); internodes longest in median area, diminishing downward and upward; axils lunate. apices digitate to subclavate, up to 2 mm thick, avellaneous when fresh (teste Oudemans).
Tramal hyphae 2-6 µm diam., thin-walled, hyaline, clamped, interwoven to generally parallel, free. Hymenium thickening significantly; basidia 60-110 x 8-9 µm, clavate, usually with attenuate base, clamped, hyaline to pale yellow under phase contrast; sterigmata 4, long, stout, subcomute.
Spores 6.8-8.3 x 6.1-7.2 µm (E = l.00-1.18; Em = 1.10; Lm = 7.27 µm), globose to subglobose, hyaline; wall thin, smooth; contents opalescent to uniguttulate; hilar appendix very large, conical, up to 2.5 µm long.
Corner (1950) correctly interpreted Oudemans' circumscription as pertaining to Clavulinopsis, but Petersen (1978a), in reorganizing three genera, transferred the epithet to Ramariopsis. Examination of the type confirms that the spores are very strongly apiculate and that the basidia are among the longest in the clavarioid fungi. Oudemans drew attention to the anise-like odor, also reported by Petersen (1971: in Persoonia 6: 225).
Oudemans associated his species with Holmskjold's circumscription of `Ramaria coralloides alba apicibus purpurascentibus', which has been cited as synonymous with Ramaria botrytis. This species has been accepted as the type of Ramaria, but Holmskjold's fungus has also been identified as some form of Clavulina cristata. Oudemans' opinion was as good as others, but no better, for no Holmskjold specimen remains, nor any authentic report on spores or other micromorphological characters. The problem, therefore, has moved from taxonomy to nomenclature, in which Holmskjold's name has been `legislated' as a Ramaria.
Oudemans reported on collections from September and December, 1900, from the same location. Two specimens at L conform to this (no. 939.194.671, l0.xii.00; no. 939.194.673, 16.xii.00) and qualify as paratypes, although their labels indicate syntypes.
