Top 20 Most Common Mushrooms in Maryland

The crowded parchment is a common mushroom that can be found on dead hardwood material. The species is so-named because it grows in very thin, sheet-like shelves, which often become folded when they run up against each other. Crowded parchment is usually found in shades of brown, tan, or orange.

The fruit body, or crust, of Xylobolus frustulatus has a woody texture and is perennial. It is mostly 1–2 mm thick, although it can be considerably thicker. The crust is frustose (cracking into small, angular polygons), and infrequently curled at the edges. The upper surface is zonate (appearing to have multiple zones of color or texture), and more or less smooth. The hymenial surface is smooth to the naked eye, although long soft hairs can be seen when viewed with a microscope. These 'hairs' are protruding acanthocystidia (cystidia bearing a few projections near the tip) and hyphae. Young layers are pale ochraceous, while older ones dull to deep brown. The fungus is inedible, and lacks any distinctive taste or odor. The hyphal system is monomitic, meaning that there are only generative hyphae (relatively undifferentiated hyphae that can develop reproductive structures) are present. These vertically arranged, short-celled hyphae form transitions to acanthocystidia, and have a diameter of about 3.5–5 µm. They are sparsely branched, and hyaline (translucent) to yellowish-brown, although those in older layers may be more strongly pigmented. Other hyphae (such as in the trama) are few or absent, although they can be most readily observed in very thin sections. Measuring 3–5 µm wide, they are vertically arranged, thin to moderately thick-walled, and form transitions to pseudocystidia. All of the hyphae of X. frustulatus lack clamp connections. Pseudocystidia (sterile structures arising deep in the subhymenium and protruding into the hymenium) are rare. Thin to moderately thick-walled, they rarely project above the basidia and acanthocystidia. The acanthocystidia are numerous, and have dimensions of 25–30 µm long by 4–5 µm wide. The basidia (spore-bearing cells) are shaped like long clubs, four-spored, and measure 25–30 by 4–5 µm. They are smooth or have a few basal protuberances (acanthobasidia). The spores are short-ellipsoid in shape, thin-walled or with a slight wall thickening, smooth, typically measuring 4.5–5 by 3–3.2 µm. They have a distinct amyloid reaction.

Crown-tipped coral(Artomyces pyxidatus) is a widespread but uncommon species in North America and Western Europe whose Latin name, meaning "box-like," is inspired by its structure. It is one of the few coral fungi to fruit on wood. After a period of absence lasting over a century, it has recently reappeared in Great Britain.

Birch mazegill(Lenzites betulina) is commonly found on decaying coniferous or deciduous woods. While its natural color is a yellowish brown, it may sometimes appear green due to its propensity to host algae. It is considered to be inedible on account of its tough and leathery texture.

This inedible shelf or bracket fungus grows in overlapping clusters and layers on hardwood stumps and fallen logs. It also causes a sapwood rot in standing trees. Check under the violet-toothed polypore's cap for its secret lilac-shaded pore surface studded with descending “teeth.”

The common greenshield lichen is a familiar species in temperate forests around the world. It can be found growing on rock outcroppings and trees in a wide variety of habitats. Individuals can grow to be quite large and may be gregarious, forming large mats or sheets on suitable surfaces. Like other lichens, the common greenshield lichen will shrivel and harden when moisture is scarce.

Witches' butter (Tremella mesenterica) has an irregularly-shaped fruitbody that can be found growing on dead hardwood branches. It has a global distribution, being found in both temperate and tropical forests. Usually yellow in color, its hues may range from subdued lemon to bright canary.

The jack-o'lantern mushroom is so-called because of its bright orange color, and because it often appears in the fall (usually before Halloween, though). This vibrant little mushroom can be found growing on decaying hardwood stumps and logs. The species does have some superficial resemblances to the highly edible chanterelle (Cantharellus cibarius), but it is toxic and should be avoided!

The coral-pink merulius is a distinctive pink mushroom that grows on rotten wood. Interestingly, this mushroom almost always appears together with the False turkey tail (Stereum ostrea). If you spot one of them, the other one is probably somewhere near.

Red chanterelles can be found growing within hardwood forests across eastern North America. These small but striking mushrooms range from orange to red to pink in color. Edible and boasting complex flavors, many chanterelles are highly sought after. The red chanterelle, though less famous than some of its close relatives, is no exception. This species can be used in all sorts of recipes, with a vaguely sweet or piney taste.
