#113: Moniliophthora perniciosa, Witches’ Broom Disease of Cacao Trees 1

#113: Moniliophthora perniciosa, Witches’ Broom Disease of Cacao Trees

Witches might not be real, but witches’ brooms certainly are – and they’re destroying chocolate! Yes, Halloween’s favorite treat (chocolate) is suffering at the hands of a disease with a Halloween-themed name: Witches’ Broom Disease.  Witches’ brooms are actually fairly common and occur on many different plants.  In chocolate trees (Cacao trees, Theobroma cacao, whose genus name literally means “food of the gods”), witches’ brooms are caused by the fungal pathogen Moniliophthora perniciosa and have an enormous economic impact on chocolate production in Central and South America.

#109: Rubroboletus satanas, Satan’s Bolete or Devil’s Mushroom

If you need a mushroom centerpiece for your Halloween party, then this is it. This large mushroom has a bulbous, bright red, reticulated base that easily invokes demonic fires (hence its common and scientific names).  As a bonus, Satan’s Bolete has a fetid odor – quite fitting, don’t you think?  Unfortunately, this mushroom is rather rare.

#108: Heimioporus betula, the Shaggy-Stalked Bolete

Noting what decorations a bolete has on its stem can be very helpful in identifying that bolete. One type of decoration you may find on a bolete’s stipe is reticulation.  Reticulation is a net-like pattern of ridges that extend partially or all the way down the stipe.  These ridges are actually an extension of the pore surface, much like decurrent gills in agarics.  The reticulum does produce spores, but is not as efficient at discharging spores because it is oriented parallel to the ground.  Heimioporus betula is hands-down the best example of reticulation in any bolote.

#106: Calostoma cinnabarinum, the Stalked Puffball-In-Aspic 2

#106: Calostoma cinnabarinum, the Stalked Puffball-In-Aspic

This is without a doubt the strangest-looking puffball-like mushroom in North America. It starts out looking like the inside of an oddly-colored egg and ends up resembling a little, red balloon glued to the top of a tiny termite mound.  This description really doesn’t do the mushroom justice, so please do an image search for “Calostoma cinnabarinum” to see what the mushroom actually looks like.

#105: Pseudohydnum gelatinosum, The Toothed Jelly Fungus 0

#105: Pseudohydnum gelatinosum, The Toothed Jelly Fungus

This is one of the strangest fungi you can find in North America. Like other jelly fungi, it is characterized by its squishy, gelatinous texture.  Most jelly fungi have a fairly disorganized, globular structure.  However, Pseudohydnum gelatinosum has a distinct stipe, pileus, and spore surface.  In fact, its spores are borne on teeth, much like the unrelated Hedgehog Mushroom (Hydnum repandum)!

#103: Grifola frondosa, The Hen of the Woods 2

#103: Grifola frondosa, The Hen of the Woods

This edible mushroom has a few common names, including: “Hen of the Woods,” “Sheepshead,” and “” It is parasitic on hardwood tree roots, so look for this mushroom around the bases of hardwoods (especially oaks and maples) in the fall.

#102: The Chicken of the Woods or Sulfur Shelf Fungus 4

#102: The Chicken of the Woods or Sulfur Shelf Fungus

This mushroom is a gateway mushroom to foraging. There is no mistaking the large, bright, yellow-orange fruiting bodies of the Chicken of the Woods.  It is also a good edible that has the look, texture, and taste of chicken when cooked (which resulted in one of its common names).

#101: Golden Chanterelles 3

#101: Golden Chanterelles

These mushrooms are the mycophagist’s (fungus-eater’s) best friends. They taste great, are large enough to eat, often fruit plentifully, are easy to spot, and are unlikely to be confused with anything else (if you know what to look for).  Golden Chanterelles are very popular in Europe.  The European species is called the “Griole” in France, while Germans call it the “”  These choice edibles can also be found in North America, where they fruit from summer through fall.  Look for chanterelles near streams, in hollows, and in other tree-covered places with abundant moisture but good drainage.  I recently found some in a small park in Northern Virginia, so they may be more common than you would expect!
