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
Recent research based on DNA comparisons have resulted in changes in taxonomic order at all levels, even the highest (fungi are now considered to be closer to animals than plants). As a result, authoritative sources of information about fungi on the Web provide differing binomial names and lineages for the same species. The Integrated Taxonomic Information System (ITIS) on-line database, http://www.itis.gov, avoids this problem by providing only sparse coverage of fungi.

Hen of the Woods

Hen of the Woods (Grifola frondosa) is one of the most easily recognized polypores of eastern North America. The numerous, overlapping, smoky-brown caps are reminiscent of a fluffed-up chicken, giving this mushroom its common name. It is found in deciduous woodlands, especially woodland edges, usually at the base of a dead or dying tree or stump. It appears in summer and fall as a large cluster of rosettes of numerous small, overlapping, fan-shaped caps rising from a single base. Tender young caps are edible after long, slow cooking.

Hen of the Woods is distinctive in appearance. A closely related species, Grifola umbellata, is similar in appearance but the caps are larger and lighter in color, and are attached near the center, not at or near the side. It is much less common.

Aspen Bolete

Aspen Bolete (Leccinum insigne) was first described in North America in 1966. In the summer and early fall it is found on the ground, widely scattered or in groups, in woods and woodland edges under aspen and possibly also under birch. The species name means “distinctive or outstanding” but the mushroom was named for the Italian soccer player Lorenzo Insigne. Most sources state that it is safe to eat, but it has recently been thought to cause gastrointestinal distress in some individuals.

Scaber stalk mushrooms can be easily identified to the genus, less easily to the species. All have whitish or pale stalks covered by numerous short, rough, projecting scales (scabers) that turn dark at maturity. Many are similar in appearance and are often misidentified as Red-capped Scaber Stalk (Leccinum aurantiacum), even in printed guides and on popular mushroom Websites. However, recent DNA analysis suggests that Red-Capped Scaber Stalk is a European species that does not occur in North America.

Aspen bolete is distinguished by the dry, orange or orangish cap that turns bluish-gray or purplish-gray when bruised or cut; the stalk that tuns blue at the base when cut; and its habit of growing under aspens.

Late Oyster Mushroom

Late Oyster Mushroom (Panellus serotinus) is common, widespread, and aptly named. It appears in the late fall with the onset of cold weather. It is found singly or in overlapping groups on the trunk or a large branch of a dead and decaying tree. It usually occurs on a hardwood, especially black cherry, but occasionally also on a conifer.

There is often no stalk. When there is a stalk it is short, thick, and attached at the side. The cap is kidney-shaped or semi-circular. It is downy and often flushed with violet when young, becoming hairless and olive-green to yellowish-green as it ages, eventually turning yellowish-olive or light brown when mature. The edges are curled under at first but flatten out with age. The gills are yellowish or orangish but fade with age. It is edible but has a mediocre taste and becomes bitter as it ages.

Phomopsis gall on hickory

There are at least 232 species of the fungus Phomopsis. Several of these produce bark galls on bitternut hickory. The galls are identical in appearance making identification of the associated species in the field impossible.

Spores are produced throughout the growing season and are spread by wind and rain splashes. It is believed that spores infect a host by entering a wound of a young twig. The fungus then spreads to branches and to the trunk. The galls do not kill the host but reduce vigor and girdle small branches causing dieback. Uninfected trees may occur near heavily infected ones.

Galls may occur singly or in clusters on the trunk and branches. They are woody, rough, more or less round swellings. They appear as tight clusters of nodules. They can be very small to 10 in diameter. If cut open they reveal disorganized woody tissue but no insect chambers or tunnels.

Peeling Puffball

Peeling Puffball (Lycoperdon marginatum) is a common and widespread, medium-sized puffball. It appears on the ground, individually, scattered, or in groups, usually in sandy soil. It is often found in the woods under deciduous or coniferous trees, but is also found in the open on roadsides and in waste places.

The skin is covered with short, erect spines that often aggregate in groups of 2 to 4 creating pyramid-shaped warts. As it ages, the outer, warty or spiny skin sloughs off in thick, irregular patches or chunks revealing the smooth, pale to dark brown inner skin below. When mature, a pore-like mouth develops at the top through which spores are released.

Peeling Puffball is distinguished by the outer skin that is covered with pyramidal warts and sloughs off in thick, irregular patches or chunks.

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.
