Summary:
Clavulina rugosa is variable but typically only slightly branched (simple or with 1-3 undivided short branches), whitish, and wrinkled, and has nearly round smooth spores on 2-spored basidia with strongly incurved sterigmata. Some authors have suggested that C. rugosa may be an atypical form of Clavulina coralloides, (Bessette(2)).
Odor:
none in particular (Lincoff), slight (Corner(2))
Taste:

Microscopic:
spores 8-9 x 6-8 microns, 2-spored basidia with strongly incurved sterigmata, (Lincoff), spores 9-14 x 8-12 microns, (10-12 x 9-10 in Oregon collection), broadly oval-elliptic, smooth, with one droplet; basidia 40-85 x 6-9.5 microns, sterigmata 6-9 microns long; hymenium thickening to 150 microns, subhymenial hyphae 3-7 microns wide, interwoven, cystidia none; hyphae 40-120 x 3-13 microns, clamped, inflating, becoming slightly thick-walled, H-connections frequent, not secondarily septate, (Corner), spores 9-12 x 8-10 microns, broadly elliptic to nearly round, smooth, inamyloid; hyphal system monomitic, (Buczacki)
Spore Deposit:
spores referred to as white (Corner(2))
Notes:
C. rugosa has been found in OR, VT, Panama, Argentina, Uruguay, Venezuela, Austria, Czech Republic, Pakistan, and Philippines, (Corner(3)).
