Clavaria appalachiensis Coker 1923
Clavulinopsis appalachiensis (Coker) Corner 1950
There are current efforts underway to determine the exact nature of its taxonomic make-up, as indicated by Joshua Brikabek.
This is a rare species with few scattered records; occurs in soils subject to run-off and acidification
1920 PA (Buck Hills Falls) in Krypto-S
1922 NC (Blowing Rock) in FMNH
1939 Nova Scotia (Kings, Glenmont) in TENN
1942 MI (fragment, no details) in OSC
1959 ONT (Algonquin PP, under hardwood) in TRTC
1959 FL (Newnan’s Lk on soil) in FLAS
1959 ONT (Nipissing, under hardwood) in TENN
Since this species is tiny and often over-looked, it is likely that the population is far more extensive than what the existing collections indicate. Habitat information is lacking to almost non-existent on both the collections and in Peterson’s Clavulinopsis of North America publication. Therefore it is difficult to estimate both potential decline or threat on a habitat basis. The singular collection from NH (unvouchered) was observed to occur in a specific habitat type that is subject to possible acidification, i.e. circumneutral intermittent stream channels without herbaceous vegetation.
Singly to gregarious in moist soil and leaf litter of mixed deciduous woods; specifically found to be in humus rich soil in intermittent drainageways subject to run-off and changing pH; collection information lists “under hardwoods” “in soil” and “in soil in light woods.” The single recent (2005) collection was from a site where other Clavulinopsis species were found (e.g. C. umbrinella) where summer rains had subsided and no vegetation or leaf litter was present. These types of sites often contain Botrychium species and have been tested to have pH levels an order of magnitude larger than the nearby forest soils. These sites are therefore subject to acid precipation and run-off.
Soil acidification which could result in a reduction or loss of its occurrence on a site-by-site basis; loss of organic content in soil
More work needs to be completed on its taxonomy (i.e. possible Clavaria?), as well as its exact distribution limits. Since so few records, no decline demonstrable although more collections are needed. The taxonomy is currently being reviewed by Joshua Brikebak.
