Name: Clavulinopsis fusiformos
Family: Clavulinaceae
Collection Date: September 13, 2011
Habitat: On wet, soggy dirt with some twigs scattered around. Underneath a large tree near other fungus.
Location: South Chagrin Reservation in Chagrin Falls, Ohio
Description: Growing in tight, dense clusters, Clavulinopsis fusiformis is widely distributed, but more common in the northern half of North America. It is distinguished from look-alikes by its clustered growth pattern, its height (5-15 cm), and its bitter taste. (Kuo, 2007).
Presumably saprobic; growing in dense clusters with fused bases, or occasionally gregariously; in woods under hardwoods or conifers, sometimes in grass; summer and fall; widely distributed but more common in northern North America. Fruiting body is typically 5-15 cm high; up to 1.5 cm wide; cylindrical and unbranched; often flattening; sometimes grooved; dry; bright or pale yellow; fading with age; white at the extreme base; usually with a somewhat pointed tip (Kuo, 2007).

Basidiomycetes Pg 52.
Fruiting body erect, unbranched (club-like) or profusely branched from a common base or “trunk” (coral-like); cap absent; spores borne on the smooth to slightly wrinkled surfaces of the upright clubs or branches. Coral and Club Fungi p. 630.
Key to Clavariaceae:
Key to Clavulina and Allies:
1a. Fruiting body unbranched or very sparsely branched (but often tufted or clustered.)
2b. Not as above- (above: fruiting body entirely brownish-black to black or blackish beneath a white powdery coating or entirely green to olive or blue-green or interior with large chambers or compartments or parasitic on insects, spiders, or truffles; spores born asexually or in acsi); may be white, but if so then not powdery; spores born on basidia.
3b. Fruiting body typically fragile or if tough then much smaller, mostly less than 7 mm thick; apex acute or blunt or occasionally enlarged. Clavaria and Allies. P. 634.
Key to Clavaria and Allies:
1b. Not as above- (above: growing on algae-covered wood or soil; fruiting body minute (up to 1.5 cm high and 1-3 mm thick)); if growing on algae, then larger/
2a. Fresh fruiting body yellow to orange, red salmon, or pink.
3a. Fruiting body yellow to orange.
4b. Fruiting body unbranched or occasionally forked (but often clustered.)
6b. Not as above- (above: fruiting body with wide, often flattened head and/or fruiting body often irregular in shape; texture rather tough; spores borne inside asci); fruiting body typically clublike to spindle-shaped or fingerlike or rarely forked; usually rather fragile; spores borne on basidia.
7a. Fruiting bodies 5-15 cm tall, usually growing in bundles or large clusters, yellow. Clavinopsis fusiformis. P. 638.
