Description:Clavaria alcicornis Zollinger & Moritzi. 1844. Flora Arch. Neerl. Indien, µm 382.
Holotypus: FH- Planta Javanica Exs. no. 1125, Tjikoya, Marz, 1843; ex herb. Patouillard.
Macroscopic: Fruiting body about 3 cm tall. Stem portion smooth, 3 mm thick, 1 cm long, producing polychotomous branches. Branches smooth, subcylindric, 3-4 ranks, polychotomous at first, dichotomous toward the apices, axils rounded-acute. Apices 2-4 mm long, bicuspidate, somewhat recurved. Color of stem dark ochre, branches slightly darker, apices deep ochraceous rose or orange ochraceous. Microscopic: Contextual hyphae strictly parallel, now inseparable (through poisoning ?), slightly inflated, clamped. Hymenium thickening; basidia short (22-30 µm long), clamped at base, 4-sterigmate.
Spores of two types; 1) spiny spores of Fungi Imperfecti, 2) smooth, refractile spores with no apiculus.
Corner (1950) accepts the species as Clavulinopsis alcicornis (Zoll. & Mor.) Corner. The type specimen was probably poisoned, resulting in what appear as agglutinated contextual hyphae, almost complete lack of basidial and hyphal detail, and a total lack of basidiospores. The parallel clamped contextual hyphae, and the 4-sterigmate, clamped basidia both indicate Corner's correct choice of genus.

Note added from Petersen, Sydowia 32: 211. 1979
I can find no specimens which match this concept exactly, but FAWCETT (1939) described branched fruitbodies under Clavaria muscoides which were `cinnamon buff' at the tips, shading to `clay color' at the base." Such colors suggest C. alcicornis, although there was no mention of the brighter cream-rose to flesh color apices as described and figured by van OVEREEM (1923: taf. 4, fig. 2). CORNER indicated that the species fruited rarely. Branched specimens at MELU under C. muscoides must be consulted, but now are almost indistinguishable from C. corniculata.
Sometime ago I described what I considered to be the type of C. alcicornis (herb. PATOUILLARD at FH) which bore no spores. I question now whether this specimen really is the type, and until this issue can be settled, I will not transfer the name to Ramariopsis, where it would belong under the generic revision published recently (PETERSEN, 1978c).
