Index to genera:Aleuria
– great orange elf-cup, orange fairy-cup, orange peel fungus, orange-peel fungus, orange-peel
Description: Aleuria aurantia does indeed look like orange peels turned inside-out and scattered by a passing hiker or motorist. The inner fertile surface is a brilliant deep orange, the outer surface paler with a somewhat dandruffy texture. The spores are ellipsoid, 13--24 x 7.5--10 µm, and covered by a network of ridges. A. aurantia is very common in the fall, and is especially abundant along gravelly forest roads, in campgrounds, and at trailhead parking areas. It is one of several ascomycetes that will discharge many spores simultaneously when disturbed, producing a visible smoke-like cloud. Sometimes this can be induced by breathing on the cups, at other times it will occur on its own when the fruitbody is removed from its collecting container.
Distribution: A. aurantia is widespread in the Northern Hemisphere.
Habitat: grassy areas on disturbed soil, in gardens, and along roadsides
Substrate: On ground, in groups or clusters.
Spores: Summer and fall
Description: reddish brown cup with short hairs on the outside; has a single septum with paraphysis that stains green in Melzer\'s reagent.
– burn site ochre cup
Description: fruitbody cup-shaped to concave to flattened, lacking a stalk; upper surface yellowish orange; underside slightly paler, darkly punctate with tufts of appressed brownish hairs.
Substrate: gregarious to massed on burned ground and burned wood
Spores: Spring through early winter
– eyelash dung cup
Description: The genus Cheilymenia is characterized by small, stipe-less, flattened saucers bearing conspicuous (under a handlens) eyelash hairs and growing on dung, rich soil, plant debris, or other materials. It appears to be closely related to Aleuria. C. fimicola (= C. coprinaria (Cooke) Boudier) is one of the dung-dwellers, occurring on cow-pies as well as the droppings of wild animals. When fresh the fruitbodies are reddish orange, then they lighten to yellowish orange in age; the hairs are brownish, and all are unbranched.
Substrate: dung, manure, or compost
Spores: spring, summer, and fall
Description: Cheilymenia stercorea occurs on mammal dung, and has branched brownish hairs near the base of the cup.
Description: Cheilymania theleboloides occurs on rotting plant remains, or horse manure and straw; its cups have whitish hairs and are more yellow.
Substrate: rotting plant remains, or horse manure and straw
Distribution: Northern hemisphere.
Substrate: Soil, especially sandy or burned.
– Cooper's truffle, fuzzy false truffle, fuzzy truffle, pine truffle
Distribution: It is ectomycorrhizal with conifers, widely distributed, and occurs almost year-round.
Spores: long cylindrical asci, each with eight smooth, broad elliptical spores that are forcibly ejected at maturity
– earth box, dwarf acorn cup, pyxie cup, stalked bonfire cup
Habitat: Occurs after conifer forest fires
Spores: The spores are smooth, ellipsoid, 11--18 x 6--9 µm, and do not contain prominent oil drops.
– brown-haired white cup, glazed cup, hairy fairy cup
– false eyelash cup, red saucer
– brown clustered ear cup
