What type of vegetation does Citharexylum and Cuminum have in common?
Citharexylum Citharexylum is a genus of flowering plants in the verbena family, Verbenaceae. It contains shrub and tree species commonly known as fiddlewoods or zitherwoods. They are native to the Americas, ranging from southern Florida and Texas in the United States to Argentina. The highest diversity occurs in Mexico and the Andes. The generic name is derived from the Greek words κιθάρα ("kithara"), meaning "lyre", and ξύλον ("xylon"), meaning "wood," referring to the use of the wood in the sounding boards of string instruments. Several species, especially "C. caudatum" and "C. spinosum", are cultivated as ornamentals.
Hypholoma capnoides Hypholoma capnoides is an edible mushroom in the family Strophariaceae. Like its poisonous or suspect relatives "H. fasciculare" ("sulphur tuft") and "H. sublateritium" ("brick caps") grows on decaying wood, for example in tufts on old tree stumps. Anyone thinking to eat this mushroom needs to be able to distinguish it from sulphur tuft, which is more common in many areas. "H. capnoides" has greyish gills due to the dark color of its spores, whereas sulphur tuft has greenish gills. It could also perhaps be confused with the deadly "Galerina marginata" or the good edible "Kuehneromyces mutabilis".
