Kavinia alboviridis
J. Ariz. Acad. Sci. 6(2): 95. 1970.
Common Name: none
Basionym: Hydnum alboviride Morgan J. Cincinnati Soc. Nat. Hist. 10: 12. 1887.
For description see Martini & 'California Mushrooms'.
Forming a thin crust on or buried in decayed conifer logs (fir, pine); uncommon, fruiting from spring through fall in the Sierra Nevada and Cascade Ranges.
Unknown.
Kavinia alboviridis can be distinguished by a thin, loose, white cottony layer with pendent yellowish olive spines, on which are formed warted greenish yellow spores. Interestingly, this odd fungus is related to the coral fungus Lentaria in order Gomphales. Steccherinum fimbriatum forms a tough, membranous crust with wart-like grayish pink to vinaceous buff spines; additional characters include dimitic-skeletal tissues, thick-walled crystal-incrusted hymenial cystidia, and smooth white spores. Steccherinum ochraceum is a similar crust fungus but forms thin, overlapping, zonate, leathery gray to ochre shelves with orange to salmon spines.
