Explore illustrated mycology posters, mushroom identification guides, and fungal comparisons, with descriptions and full-resolution images.
The panels compare Arrhenia bigelowii, gerardiana, philonotis, and telmatiaea. They show obvious scales, a smooth mature desquamated cap, subtle embedded scale patterns, fine hairs, and lighter or darker adpressed scale patterns. Scale bars represent 10 millimetres.
Amanita rubescens is marked edible but toxic raw or undercooked and is distinguished by pink or wine tones and reddening wounds. Amanita excelsa var. spissa is discouraged and toxic raw or undercooked, with a gray-brown cap, map-like patches, a striated ring, and turnip odor. Amanita pantherina is toxic, with pure-white cap warts, a striated cap margin, an unstriated ring, and a ridged volva.

Blond and black morels have pitted caps joined to the stem; Morchella semilibera has a cap attached halfway down. Verpa bohemica and Verpa conica have caps attached only at the stem tip. These groups are labelled edible but toxic raw. Gyromitra is labelled toxic to deadly and has a brain-like cap with irregular internal cavities.
Neoboletus erythropus has a brown cap, red pores, a punctate stem, and intense blue staining. Suillellus luridus has orange pores, a reticulate stem, and intense blue staining. Toxic Rubroboletus satanas has a whitish cap, red pores, and medium blue staining. Bitter Caloboletus calopus has a whitish cap, yellow pores, a yellow-to-red reticulate stem, and medium blue staining.
Rubroboletus satanas is shown with medium blue staining, a white cap, a netted stem, and a warning symbol. Neoboletus erythropus is shown with intense blue staining, a brown cap, a smooth or punctate stem, and a label requiring 20 minutes of cooking.
The chart groups illustrated boletes as ceps, choice edibles, mediocre edibles, not edible, poisonous, poisonous raw, and inedible. An anatomy panel labels cap, cuticle, tubes, pores, flesh, stem, and mycelium. Stem ornamentation examples include smooth, netted, scabered, dotted, granulated, and false-netted surfaces. The legend explains oxidation, rarity, and toxicity.
Species are grouped as ceps, choice edibles, mediocre edibles, worthless edibles, poisonous, poisonous raw, and inedible. A recognition panel labels cap, pores, stem, cuticle, and flesh. The legend explains staining, rarity, laxative cuticle, fibrous stems, and variable toxicity, and the poster advises recording habitat, staining, smell, and taste.
A smaller bud is separated from the parent cell by a septum, with a bud scar at the base. Labels identify vesicles, Golgi apparatus, vacuole, cytoplasm, cell wall, mitochondrion, cell membrane, rough and smooth endoplasmic reticulum, nucleolus, and nucleus.
A parent cell and smaller bud are separated by a septum. Labels identify the cell wall, cell membrane, cytoplasm, vesicle, ribosomes, Golgi apparatus, endoplasmic reticulum, smooth ER, nucleus, nucleolus, mitochondrion, vacuole, lysosome, peroxisome, and bud scar.
The central Dikarya branch divides into Basidiomycota and Ascomycota, with representative mushrooms, boletes, brackets, rusts, smuts, cup fungi, morels, truffles, lichens, moulds, and yeasts. Lower branches show Entorrhizomycota, Zoopagomycota, Mucoromycota, Blastocladiomycota, Chytridiomycota, Sanchytriomycota, Aphelida, and Opisthosporidia. Dashed branches indicate proposed relationships.
The tree labels Basidiomycota, Ascomycota, Glomeromycota, Zygomycota, and Chytridiomycota, illustrated respectively by mushrooms, a morel, branching hyphae with round structures, upright sporangia, and a microscopic branching form. Animalia appears as a comparison branch.
The Cantharellus section contains seven girolles, the Craterellus section contains eight chanterelles and trumpets, and the Gomphus section contains two violet chanterelles. The legend marks species as common, unusual, or rare and advises against collecting rare species for consumption.
Cap features include scales, zonations, areolae, and striations. Spore-bearing surfaces include tubes, pores, teeth, and gills. Stem structures include the ring or skirt, stipe, reticulum, scales, volva, basal bulb, and branching mycelial threads.
Three rows compare species in Xerocomus, Imleria, Pulchroboletus, Alessioporus, Rheubarbariboletus, Hortiboletus, and Xerocomellus. Colored longitudinal sections distinguish each species by internal cap, flesh, stem, and stem-base patterns.
