Astraeus (fungus)

Astraeus, the false earthstars, is a genus of gasteroid Boletales fungi (Diplocystidiaceae) whose hygroscopic rays open and close with humidity; type species A. hygrometricus, distinct from Geastrum, ectomycorrhizal, edible, uncultivatable.

Astraeus hygrometricus

Astraeus hygrometricus, the barometer or hygroscopic earthstar (basionym Geastrum hygrometricum), is a Boletales fungus whose hygroscopic rays open in rain and close in drought; molecular work shows it is a complex of cryptic species.

Calvatia gigantea

Calvatia gigantea, the giant puffball (Riesenbovist, vesse de loup géante), is a large stemless Lycoperdaceae puffball fungus, up to 65 cm, smooth white skin, edible when gleba is white, basionym Lycoperdon giganteum Batsch 1783.

Clathrus archeri

Clathrus archeri (octopus stinkhorn, devil's fingers; syn. Anthurus archeri) is a red-armed saprobic stinkhorn fungus native to Australia and New Zealand, introduced to Europe around 1920, potentially invasive, with future range contraction expected in Australia and expansion in Europe.

Clathrus ruber

Clathrus ruber (red cage, latticed or basket stinkhorn), type species of Clathrus in Phallales, is a saprophytic fungus whose fruit body expands from a whitish egg into a red lattice ball with foul olive-green gleba dispersed by insects; native to Mediterranean Europe, introduced elsewhere.

Crucibulum

Crucibulum is a small genus of bird's nest fungi whose urn-shaped fruiting bodies contain whitish spore packets that raindrops splash out to adhere to nearby surfaces.

Cyathus

Cyathus (bird's nest fungi) is a genus of gasteroid fungi in Nidulariaceae, established 1768, with over 130 cup-shaped species whose peridioles are splash-dispersed by raindrops and attached by funicular cords.

Cyathus olla

Cyathus olla, the field bird's nest fungus (Nidulariaceae), is a 1–1.5 cm splash-cup basidiomycete with 8–10 large peridioles ejected by raindrops; basionym Peziza olla Batsch 1783, common in Europe and North America.

Cyathus stercoreus

Cyathus stercoreus, the dung bird's nest fungus (Nidulariaceae, Basidiomycota), a coprophilous splash-cup fungus with huge 20-40 µm spores, peridioles dispersed by rain and herbivore gut passage, and lignin-degrading enzymes.

Cyathus striatus

Cyathus striatus, the fluted bird's nest fungus, a saprobic Nidulariaceae basidiomycete with shaggy brown cups, striated inner walls, peridioles with funiculi, and rain splash-cup spore dispersal on woody debris.

Earthstar morphology and development

Earthstar morphology and development describes how earthstar fungi are constructed and develop: a three-layered exoperidium splits into rays that lift the spore sac, and raindrops pump spores out passively.

Gasteroid fungi

Gasteroid fungi, historically called Gastromycetes, are basidiomycete fungi, including puffballs, earthstars, stinkhorns, and false truffles, that produce spores internally; molecular studies show the group is polyphyletic, not a natural lineage.

Geastrales

Geastrales (earth-stars) is an order of gasteroid basidiomycete fungi in subclass Phallomycetidae, family Geastraceae, genus Geastrum with 140 species; star-shaped spore-sac fruiting bodies, statismospores, worldwide litter decomposers.

Geastrum

Geastrum (earthstars) is a genus of Geastraceae fungi whose star-shaped fruiting bodies open into rays around a spore sac. Molecular phylogenies since 2014 replaced morphology-only classifications and revealed many hidden species, including within G. triplex.

Geastrum quadrifidum

Geastrum quadrifidum, the rayed earthstar, is a fornicate Geastraceae fungus described by Persoon in 1794, with 4-5 non-hygroscopic rays lifting a stalked, hoary spore case with a conical peristome; found in coniferous woodland across Europe and the Americas.

Geastrum triplex

Geastrum triplex, the collared earthstar, is a saprobic Geastraceae fungus on all continents except Antarctica, the largest Geastrum, with 4-8 rays, a saucer collar, and rain-puff spore dispersal.

Gomphales

Gomphales is an order of basidiomycete fungi in Agaricomycetes, subclass Phallomycetidae, proposed by Jülich in 1981; includes coral fungi (Ramaria), fairy clubs, and false truffles, with ferric-positive hymenia, chiastic basidia, and Cretaceous-aged gomphoid lineages.

Lycoperdaceae

Lycoperdaceae, the true puffball family (Agaricales), includes Lycoperdon, Bovista, Calvatia, and Disciseda; angiocarpic fruit bodies, about 430 species, taxonomic status debated versus Agaricaceae.

Mutinus elegans

Mutinus elegans, the elegant stinkhorn or devil's dipstick, a Phallaceae fungus with a pink-orange hollow stalk and olive-green foul gleba; insect-dispersed spores, edible egg stage, distinct from M. caninus and Phallus rubicundus.

Myriostoma

Myriostoma, the pepperpot earthstars, is a genus of Geastraceae fungi with a multi-stalked, many-pored spore sac. Once monotypic under Myriostoma coliforme, it was split into several species by 2017 integrative taxonomy.

Myriostoma coliforme

Myriostoma coliforme (Dicks.) Corda, the pepper pot earthstar, is a rare gasteroid fungus (Geastraceae) with multiple endoperidial stomata and stalks and reticulate spores; a 2017 study split it into four species, restricting it to Europe, North America, and Hawai'i.

Nidula

Nidula is a genus of bird's nest fungi (Nidulariaceae, Agaricales), described in 1902 with about seven accepted species such as N. candida and N. shingbaensis; its cordless, gel-embedded, sticky peridioles distinguish it from Cyathus and Crucibulum.

Nidularia

Nidularia (Fr. 1817) is the type genus of the bird's nest fungi family Nidulariaceae, with globose fruiting bodies whose thin peridium dehisces at maturity; peridioles lack funiculi, sit in gel, and splash only about 1.5 cm, unlike Cyathus and Crucibulum.

Nidulariaceae

Nidulariaceae, the bird's nest fungi, are saprotrophic Agaricales (Basidiomycota) with cup-shaped fruiting bodies whose peridioles are rain-splash dispersed; genera include Cyathus, Crucibulum, Nidula, Nidularia, Mycocalia, and Retiperidiolia.

Phallaceae

Phallaceae, the stinkhorn family (Corda, 1842), are gasteroid Basidiomycota fungi in Phallales whose foul-smelling gleba attracts insects for spore dispersal; fruit bodies emerge from eggs within minutes and include edible Phallus species.

Phallales

Phallales is an order of fungi in the class Agaricomycetes whose best-known members are the stinkhorns, foul-smelling fungi that rely on insects rather than wind to disperse their spores.

Phallus impudicus

Phallus impudicus, the common stinkhorn, is a basidiomycete fungus (Phallales, Phallaceae) described by Linnaeus in 1753, whose fetid gleba attracts spore-dispersing flies; egg stage considered edible.

Phallus indusiatus

Phallus indusiatus, the bridal veil stinkhorn or veiled lady (synonym Dictyophora indusiata), is a tropical Phallaceae fungus with a lacy white indusium, insect-dispersed spores, edible and used in Chinese medicine since 618 AD; a species complex once thought circum-tropical.

Puffball

Puffball, common name for gasteroid Basidiomycete fungi (Lycoperdon, Bovista, Calvatia, Vascellum, Morganella) whose spherical fruitbodies release trillions of internal spores in puffs through an apical pore; giant puffball Calvatia gigantea is a choice edible, unlike Amanita egg lookalikes.

Sphaerobolus

Sphaerobolus, the artillery or cannonball fungus (Geastraceae, Basidiomycota), ejects a 1-mm gleba up to 6 m by osmotic membrane eversion; species include S. stellatus, S. iowensis, and S. ingoldii.
