Key to Clubs:
Clavaria - the classic "club" fungus, individual delicate clubs coming up from the ground, usually around 5cm high and .5cm wide. They are in the Agaricales and probably somewhat related to the waxy cap gilled mushrooms (Hygrophoroid). Found on the ground, but probably saprophytic.
C. acuta (falcata) - white with translucent base (almost like an earth tongue). <8cm high, <.3cm wide
Similar club shaped fungi unrelated to each other, usually <10cm high, <0.5cm wide. Found on the ground, but also probably saprophytic.
C. 'fusiformis' - fused clusters? Bitter? More yellow?
C. luteoalba (Clavaria gracillima) - paler tip, hollow inside
Clavicorona (Artomyces) taxophila - white club with crown shape margin. Related to the Russulales (with amyloid sometime slightly roughened spores darkening in iodine). Smaller, <3cm high, <.5cm wide.
Clavariadelphus - tougher, wrinkled clubs (sometimes like veined fungi). Found on the ground. They are closely related to the veined fungi Gomphus and Turbinellus (not surprisingly) and to the corals Ramaria (very surprisingly) in the Gomphales. They may be mycorrhizal.
Macrotyphula juncea - pale, tall, <10cm, <2mm wide on woody debris.
Typhula phacorrhiza - similar, but with a sclerotium (ball of nutrients) attached to the bottom.
T. sclerotioides - very similar to T. ishikariensis, on stems and leaves.
Pterula - similar hair-like clubs growing separately or in tufts.
Also consider Multiclavula.
Multiclavula vernalis grp - the only other "basidio" lichen besides the gilled Lichenompahlia. Always associated with algae (like all lichens). <2cm tall, 1-2mm wide. Related to the Cantharellales. Small Typhula have a sclerotium.
Mucronella - individual teeth hanging down from wood resembling teeth or crusts, but sometimes growing up when young like club fungi. They are also more individual like clubs than like teeth fungi, so they are found on both pages. Each tooth is usually <1cm long. Saprophytic. They are in the Agaricales.
M. fusiformis - w/
M. pendula - with a tiny stem, looks more watery
