    Black Velvet Boletes (Tylopilus alboater)

    Published: Aug 26, 2023 Modified: Aug 28, 2023 Author: Alan Bergo

    A beautiful black mushroom with a distinct nutty flavor, black velvet boletes (Tylopilus alboater) are a must try for any mushroom hunter. As seeing even a single worm is rare, these are an edible mushroom worth the quest to find. They're the best of the genus Tylopilus I've eaten to date, and I prefer them to my local porcini. The tricky part is finding them.

    Black Velvet Bolete Identification

    Easy to identify for beginning foragers, black velvet boletes have a number of distinct characteristics to look for. Here's a quick list of the most noticeable traits.

    • Young mushrooms are usually covered with a whitish to gray bloom.
    • These are a non-bitter bolete, with a mild, mushroom flavor nibbled raw, although bitterness is reported occasionally in some collections.
    • These are firm, heavy mushrooms with thick, meaty stems, colored like the cap or paler.
    • The broadly convex cap is smooth, suede-like and velvety.
    • The stem and cap are black to dark grayish brown.
    • Pores are white and tight when young, becoming tinted pink with age.
    • Subtle pink staining when sliced, especially over the pores.
    • Growing with oak trees, particularly red oak.
    • With age the caps may be finely cracked, light weight and spongy.
    • The cap will stain pink with a drop of ammonia.

    Where to Find

    Tylopilus alboater are mycorrhizal with hardwood trees, especially red oak trees. It may grow singularly, scattered, or in groups. It's widely distributed east of the Rocky Mountains in North America.

    It's rare in Minnesota and Wisconsin where I hunt, which is the edge of their western range. It's also documented and enjoyed in Eastern Asia.

    It grows after the summer rains from July-Sept, around the same time as King boletes, and other species in the genus Tylopilus. The mushrooms pictured in this post I harvested the last week of July, a short drive east of Eau Claire Wi.

    Look for open, grassy areas in deciduous woods near red oaks, especially areas near streams that hold water.

    Look Alikes

    There's very few mushrooms that resemble T. alboater and none of them are poisonous to my knowledge. T. atronicotianus is the most well known, the old man of the woods I include for beginners but it's a bit of a stretch.

    False Black Velvet Bolete

    The false black velvet bolete Tylopilus atronicotianus is the trickiest look alike. Like many Tylopilus, they're said to be bitter, but not poisonous. They have a brown-ish color to their cap, lack the velvety texture of T. alboater, and have a reddish brown spore print. Their range shouldn't extend as far west and they're mostly documented around New York State.

    Old Man of the Woods

    The old man of the woods (Strombilomyces spp) also grows in mixed hardwood forests at the same time. It also has pronounced red staining when cut which could confuse beginning foragers.

    It's easy to separate any Strombilomyces from Tylopilus. Strombilomyces don't have a pink hue to the pores and the cap is shaggy, not smooth. It has a also has a blackish-brown spore print where Tylopilus have pink spores. See a few of the differences in the infographic below.

    Cooking

    Unlike king boletes that must be processed immediately due to bug damage, I had a few Tylopilus last over two weeks in my fridge. The bug resistance makes these one of the finest boletes to eat fresh I've had, although they can be dried too.

    Even subtle differences in preparation seemed to bring out different flavors in them. Thinly sliced stems fried nearly crisp tasted cheesy, with a rich umami flavor. Thick sliced caps are tender and mildly mushroomy.

    Like most mushrooms, cooking with cream amplifies their flavor and will have dinner guests licking the plate. They're wonderful anywhere you'd use porcini and great in a blend of summer mushrooms.

    Mature mushrooms should have the stems sliced separately.

    Mostly I ate mine with simple preparations to let them take center stage, but using them in my pasta alla checca would be good too. A few other ideas are pictured below.

    Simmering with a braise of sausages and tomato highlighted their texture and gave pops of flavor.

    Older mushrooms should be dried as they become soft and get a foam-like texture when old. Dried mushrooms are perfect for soup or grinding to a powder and crusting meat or fish.

      Hello, Alan,
      My partner and I have enjoyed a number of your recipes, especially this one for resinous polypore:
      https://foragerchef.com/resinous-polypore-ischnoderma-resinosum/
      Today we found some bay polypore, which has some characteristics in common with resinous polypore. We're wondering if you've ever tried cooking them? I've noticed that almost everybody says they are inedible because they're tough and bitter, which I think is pretty much what they say about resinous polypore, and no one says they're poisonous. That has us thinking that your recipe could work with the bay polypore, too. Any thoughts?

        Hi Art. I haven't tried them as I haven't found them. I would try them if they have nice tender edges. There's probably a lot of mushrooms that get relegated to the unknown or inedible category that actually have uses, provided they're harvested at the right stage.

      I can't believe how different MushroomExpert's description of the taste differs from your experience!

      > Odor not distinctive, or sometimes foul; taste not distinctive.

        I'd assume they're referring to sampling raw in the field there, which would be correct.

      I live in North East Ohio and am fortunate to live on land that provides Boletes , on any give day Ive foraged between 10-25 lbs. of various species of boletes, the black velvet Boletes are plentiful and amazingly delicious. Thank you for this post and video. Ive prepared the Black velvet Boletes with seasoned gluten free flour cumin smoked paprika sea salt and pepper, them roasted with thyme rosemary and tarragon. Recently I’ve prepared a mushroom potato chowder using them and other boletes. Now I’m looking forward to cooking them with dairy free cream and serving over quinoa, or millet or rice. As our diet is gluten, dairy and corn soy and meat free. This post inspires me to try other options! Thank you.

        Glad to be helpful. One thing I'd suggest is slicing the caps and stems separately when they're slightly larger and sauteeing them together.

      I started to get excited about finding a bolete that isn't so susceptible to bugs and worms with distinct coloring & shape. Add to that nutting flavor? I'm in! And then you told us where they were found.... sometimes living in the Pacific Northwest has distinct disadvantages. I do enjoy your posts and associated recipe ideas. Adapting the recipe it will have to be, this time!

      Alan, I loved reading about this mushroom but it is disappointing that it is rarely found in Minnesota. By the way, Old Man of the Woods is one of my favorite mushrooms. I LOVE the woodsy taste. They are good with eggs. Give them another try. I know others who also their tasting both intriguing and delicious.

        Hey Elizabeth. I know it stinks they're rare. One of my friends found some at Jay Cooke. I'll consider the old man if I see some good ones soon, but no promises 🙂

      Sounds like a wonderful mushroom, hope to meet it and taste it some day. Thanks for sharing about it. We don't have it in our area, West of the rockies. Even beautiful to look at.

      If you're out in my neck of the woods (WNY), you do have to contend with Tylopilus atronicotianus, but i believe it stains differently to ammonia (orange/yellow if memory serves). Sadly they also like red oak...
