Minnesota Fungi
Kingdom Fungi |
Fungi is the kingdom of living organisms that is characterized by lacking chlorophyll, feeding on dead and decaying organic matter, producing spores, and having cells with cell walls that contain chitin. The order includes mushrooms, puffballs, rusts, smuts, sac fungi, molds, yeasts, Penicillium, bread molds, and organisms that cause plant and animal diseases such as athlete’s foot and leaf spot. While there are about 100,000 described fungi species, there are estimated to be over 1,500,000 species worldwide. According to the Bell Museum of Natural History, there are 9,000 species expected to be native to Minnesota “based on the number of vascular plant species native to the state and the ratio of fungi to vascular plants for well documented parts of Europe.” To date, only two states have declared a state mushroom: Minnesota and Oregon. In 1984, the Minnesota legislature designated the Yellow Morel (Morchella esculenta) as the state mushroom of Minnesota. Taxonomy |

Dyer’s Polypore |
|||||
Dyer’s Polypore (Phaeolus schweinitzii) is one of the most common large polypores in coniferous forests throughout North America. It is used to prepare fabric dyes of various colors, but is also a significant pest to the timber industry in western United States. The fruiting body is a large, bracket-shaped polypore (conk). It usually appears on the ground as a rosette or an overlapping tier of brackets at or near the base of a large coniferous tree. In Minnesota it is most common on white pine. It attacks the living roots and the heartwood of older trees, causing the disease called red-brown butt rot. The lower 10 to 20 feet of the trunk, the most valuable part for the timber industry, is weakened or hollowed, making the tree susceptible to falling over. On young trees the fungus causes root rot which is also fatal. The cap is 2″ to 12″ wide and circular when growing on the ground, semicircular or fan-shaped when on a trunk. When young it is soft, spongy, light brownish-yellow to orange, and densely covered with velvety hairs. As it ages it becomes hard, less hairy, and turns dark brown from the center outwards. Older specimens are brittle and dark brown or black, looking something like a cow pie. It is probably poisonous. |

Hexagonal-pored Polypore |
|||||
Hexagonal-pored Polypore (Neofavolus alveolaris) is one of the first mushrooms to appear in woodlands in the spring. It occurs in Europe, Japan, and North America east of the Rocky Mountains. In the United States it is especially common east of the Great Plains. It first appears in May, the same time as morels, and persists through November. It grows on fallen branches and small logs of hardwoods. The fruiting body is a semicircular to kidney-shaped, shelf-like bracket. When it first appears in late spring it is orange or orangish. It is at this stage that it is most easily recognized. The upper surface is covered with minute scales or delicate fibers. As the season progresses it fades to yellowish or nearly white. It usually has a short, stubby laterally positioned stalk. The pore surface is white to pale yellowish and is covered with conspicuous, large, diamond-shaped or six-sided pores. The pores are not all hexagonal, as the bracket’s common name suggests. Hexagonal-pored Polypore is not poisonous but the bracket is too small and the flesh is too tough to be edible. |

Devil’s Urn |
|||||
Devil’s Urn (Urnula craterium) is one of the first mushrooms to appear in forests and woodlands in the east. It occurs in the United States east of the Great Plains, and also in Washington State. It is common in Minnesota but often overlooked due to its dark color and its somewhat leaf-like appearance. In addition, it is often buried or half-buried in the duff. It appears in the spring usually in groups, sometimes singly. It grows on or next to decaying logs, on twigs, or on the ground attached to buried wood. The mature mushroom is 1¼″ to 4¼″ high and ¾″ to 2¾″ in diameter. The fruiting body is a closed orb at first, and looks a lot like Dead Man’s Fingers. It soon opens at the top becoming deeply cup-shaped. The margins are curved inward, toothed, and appear torn. The sterile outer surface is rough and pinkish-gray or dark brown at first, becoming smooth and black to brownish-black with age. The fertile inner surface is smooth and brownish-black to black. There is usually a distinct narrow stalk at the base. The flesh is tough and leathery or fibrous. It is probably not poisonous but is too tough to be worth eating. |

Purple Bordered Leaf Spot |
|||||
Phyllosticta minima is a common and widespread fungus. It occurs in eastern North America and west to the Great Plains. It causes a disease known as Purple Bordered Leaf Spot on maples. It infects mostly Amur, Japanese, red, and silver maple, but also mountain and sugar maple, and in other areas, Tartarian and sycamore maple. The infected leaf develops small, round, tan spots with purple or brown margins. Tiny, black, pimple-like fruiting bodies form in each spot. The dead tissue in the middle of the spot sometimes breaks away, leaving a small hole. Infections are most common in wet years and on the bottom third of the tree. Some infected leaves may eventually turn brown and drop off the tree, but most trees are able to withstand the infection. Control involves removing leaves with spots from the tree, and raking up and removing fallen leaves. That prevents further infections in the current growing season, and reduces the number of infected leaves that will overwinter. |

||||
Gilled Polypore |
|||||
Gilled Polypore (Lenzites betulina) looks very much like a Turkey Tail but the pore surface on the underside has gills. It is widespread across Europe, Asia, and North and South America. In the United States it is very common from the East Coast to the Great Lakes states, south to Texas, and on the West Coast. It is less common in Minnesota where it is at the western edge of its range. It is found usually in overlapping rows or columns on logs and stumps of a wide variety of hardwoods, especially oak and willow. The name Gilled Polypore sounds like an oxymoron but accurately describes this mushroom. The fruiting body is a small, fan-shaped to nearly round, shelf-like bracket. The upper surface is concentrically zoned with varying textures and and colors, and is densely hairy. The gills are white when young but darken as they age. The flesh is thin, tough, and inedible. |

Capitalization of Common Names
Fungi common names are governed by International Code of Nomenclature for algae, fungi, and plants (ICN). According to the ICN, fungi common names can be either capitalized or not. In Britain fungi common names are governed by The British Mycological Society (BMS). The BMS formed a working party in 2005 to standardize common names of fungi. The project is ongoing, but a current checklist is available on the BMS Website. According to BMS, “the use of capitals for the English name in published texts will be to an extent determined by the publisher.” The BMS checklist uses capitalized common English language names. Most authors today also use capitalized common names for fungi. MinnesotaSeasons.com will adhere to the convention adopted by BMS.
