Shiitake Mushrooms: The Complete Guide

The second most popular and third most cultivated mushrooms in the world? Enjoyed by Chinese and Japanese Royalty for thousands of years? Shiitake mushrooms with their unique brown cap and milky-white under are as delicious as they are beautiful.
In this guide, we will explore these famous wild mushrooms and uncover why they have been enjoyed for such a long time (since Medieval Asia), their health benefits, where to find them, what to do with them once you have them, and how to prepare or preserve them.
Warning: Although consumed raw in many Asian cuisines, a German study discovered that eating raw shiitake mushrooms causes Shiitake Dermatitis, a skin reaction for people allergic to polysaccharides (link).

Five Shiitake Mushroom Facts!


  • They have a rich umami flavor and chewy, meaty texture.
  • After the button mushroom, they are the second most commonly consumed mushroom in the world.
  • Top 5 most profitable mushrooms for farmers to grow.
  • They are mostly farmed rather than forged.
  • Shiitakes have been used for food and medicine in China, Japan, and Korea since 960-1127 CE.

Five Health Benefits Of Shiitake Mushrooms


  • Enhanced Weight Loss - Studies show that shiitake mushrooms support weight loss in animals, with human clinical trials showing beneficial effects in humans (link). According to the study, shiitake mushrooms contain hypolipidaemic (fat-reducing) compounds that reduce food intake and plasma lipid fat levels, mitigate nutrition absorption, and boost satiety.
  • Boost Immune System - Increased intake of shiitake mushroom can increase your cell effector functions and improve your overall gut health according to this study (link). The participants consumed 5 to 10 grams of dried shiitake mushrooms daily for four weeks. Subsequent blood sample results showed reduced CRP (inflammatory) levels and improved cell proliferation (an increase in the number of cells).
  • Source of Vitamin D - Vitamin D boosts bone health, reduces the risk of heart disease, improves absorption of phosphorus and calcium and inhibits autoimmune diseases. You get substantial amounts of Vitamin D2 and D3 from shiitake mushrooms depending on the method of growth.
    When grown in decent amounts of sunlight, studies show that the mushrooms provide high contents of Vitamin D3, the vitamin's most bioavailable form (link). If you grow your mushrooms in limited UV light, you get supplemental amounts of vitamin D2, which raises plasma levels by over 50% over a 12-week period according to this study (link). 
  • Boost Energy and Improve Brain Function - Shiitake mushrooms contain high contents of Vitamin B2 and B12, essential for an energy boost and improved cognitive function (link). 
  • Promote Skin Health - Although consumers with allergies may suffer from Shiitake Dermatitis, the mushrooms contain high amounts of Vitamin A and E. Together with the Selenium, the vitamins help reduce acne severity and skin scarring (link).

Commonly Found Types Of Shiitake Mushrooms


Shiitake mushrooms don't come in a variety of species like morel mushrooms. However, research and increased commercial production resulted in the introduction of three strains that vary depending on the weather they grow best in. They include:
Snow Cap Shiitake (Cold Weather) - This Shiitake strain grows well in cold weather and produces beautiful, brown, uniform, thick-fleshed caps with white lacey pigmentation. The strains heaviest fruiting takes place during early spring and late fall. Their ability to grow over a long outdoor season naturally makes them a favorite for foraging (link).
WW70 Shiitake (Warm Weather) - This strain grows well in warm weather and produces one of the most beautiful ornamentations of the three strains. You get mushrooms with dark-brown caps with a variety of beautiful contrasting dark shades. The strain fruits between late summer and late fall, one of the longest periods of the three strains. The WW70 strain responds poorly to force fruiting, it's prudent to avoid it (link).
Native Harvest Shiitake (wide range) - The NHS strain grows vigorously, fast and for the longest time both in the North and South. The strain first grew on oak but also grows well on Red Maple and other common tree species. Unlike the other wide range strains, the NHS strain offers you a late flush - a bonus for your table during Thanksgiving! This strain's spawn runs 6 to 12 months (link).

Differences Between True And False Shiitakes

False Shiitakes
  • An irregular/bent shape
  • Inwards bulging
  • Wavy and lobed
  • Freely hanging from the stem
  • When you slice it, a false morel isn't hollow and filled with cotton like fibers inside.
True Shiitakes
  • Smooth uniform shape
  • Light-dark brown color
  • Pitted inwards
  • Covered in pits and ridges
  • Directly attached to the stem
  • Once you slice your shiitake, it should be hollow from the bottom of the stem to tip of the cap

History Of Shiitake Mushrooms As Medicine


Shiitake mushrooms helped people in Medieval Asia to prevent common colds, fight hunger, and boost energy levels (link). In East Asia, Shiitake Mushrooms were a delicacy preserved for royalty because of their benefits, taste, and cost.
They mostly grew in East Asia, particularly Japan, China, Korea, and Taiwan. Farming of shiitake mushrooms spread to other regions in the 1970s like USA, Singapore, and parts of Europe because of their nutritional and medicinal benefits and commercial viability.

How To Use Shiitake Mushrooms As Medicine


Shiitake mushrooms contain high fat, protein, carbohydrate, mineral, and vitamin content. Some of the medicinal and therapeutic benefits include:
Antitumor Properties - Can prevent and inhibit the growth and formation of tumors (link).
Antimicrobial Properties - May inhibits the growth and reproduction of microorganisms (link). 
Antibacterial Properties - Shown to interfere with the growth and reproduction of bacteria (link).
Antiviral Properties - Could help in the prevention and treatment of viral infections (link).
Immunomodulation Capabilities - Helps in the alteration of the immune system into desired levels (link).
Cardiovascular Health Properties - Helps in maintaining sound heart health (link). 
Hepatoprotective Properties - Could prevent liver damage (link).
Hemagglutination Capabilities - Could prevent the clumping of red blood cell particles (link).
Shiitake Dosage - The appropriate dosage of shiitake for you depends on a number of factors like your age, health, and allergies. No tangible evidence indicates the right dosage.
Pharmacists advise users to take it according to the directions on the product and consult your physician before use.
Side Effects of Shiitakes - The information about the side effects of consuming shiitake medicine remains scarce. Pharmacists, however, advice pregnant mothers, breastfeeding mothers, and people with blood disorders like eosinophilia (higher than normal white blood cell count) to avoid it (link).

What To Look Out For When Buying Shiitake Mushrooms


Smell - Dried shiitake mushrooms that are edible produce a sulfur-like smell. Fresh ones should produce an earthy smell that is not overly pungent.
Sight - Fresh shiitakes should have a light-dark brown pigment. Dried ones are mild-dark brown in color.
Touch - Fresh shiitakes are damp and spongy whereas dried ones are firm to touch.


How To Grow Shiitake Mushrooms

Although indigenous to East Asia region (Japan, China, and Korea), Shiitake cultivation and production spread to other areas like the United States (link).
Shiitake Mushrooms can be grown at home, but most production is done in large-scale in Japan, China, and the United States. This is why they are the second-most common mushroom species in the world after the button mushroom (link).
Shiitakes grow best on freshly cut logs of hardwood trees (hii' means hardwood in Japanese) like oak and sugar maple trees.

How to Grow Shiitake Mushrooms: 

1. Inoculate your logs with the fungus, get plugs (30 to 40 plugs per log), and insert holes drilled into the logs.
2. Fill the plugs with sawdust, fungal inoculum (commonly referred to as pores' or yphae'), and grain material as nutrients for the fungus.
3. Seal the holes with bee or cheese wax or paraffin and keep these inoculated ones off the ground and in 80-100% shade.
4. The fungus requires moisture from the wood to grow so during dry weather, always wet the logs well.
5. Your logs need 8 to 18 months for the fungus to grow through, and it should eventually fruit to produce shiitake mushrooms on its own.
    You can watch this YouTube video for more details (link).

    “Shocking” Your Shiitakes:

    You can shock or force your shiitakes to grow faster by:
    1. Soaking your logs in cold water for 12 to 24 hours during warmer months.
    2. Maintain them in 50 degrees minimum night temperatures.
    3. Once shocked, stack your logs in A-frame arrangement or at an angle against a structure.
    4. If fruiting fails to occur in weeks, you need to shock your logs again.
    5. If they have fruited, wait 6-8 weeks and shock again.
    6. You should see small white dots or bumps called pins. Pinning is the early process of mushroom growth.
    7. From this point until harvest, keep your logs covered with a blanket and a canopy or plastic bag during rainy weather. Too much water causes waterlogged, saggy shiitakes.

    Environment Shiitake Mushrooms Grow In



    Seasons - Because of their popularity and commercial viability, shiitakes grow throughout the year. There are different strands ideal for warm, cold and mild weather conditions. The best planting time, however, is between late summer and late fall.
    Shaded/Lit Woodlands - Your shiitakes can grow in both lit and shaded environments. Shaded environments offer faster growth whereas lighted ones offer shiitakes with higher nutritional value.
    Soil - Your shiitakes grow well on logs compared to soils. Sawdust replaces soil in many commercial production areas for faster growth and production of quality mushrooms.

    Foraging For Shiitake Mushrooms

    When foraging we would always recommend using mushroom knife for ease of use, and a clean cut. Interested in learning more about mushroom knives? Click Here For The Complete Guide To Mushroom Knives
    Country - Shiitake Mushrooms grow wild in parts of Asia (China, Japan, and Korea) and are cultivated in the United States.
    Time - In Japan (the largest producer of shiitakes), shiitake cultivation takes place during spring (March to May) and autumn (September to November). In China, shiitake growth happens during spring (mid-March to mid-May) and autumn (September to November).

    In the US, shiitake mushrooms are spread in various states, produced in private farms for commercial purposes. Like in most other shiitake producing countries, production can be annual when the mushrooms are subjected to specific environmental conditions.
    Climate - You get the highest shiitake mushroom yields during the hot and wet climate, between late summer and late fall.
    Environment - Shiitakes grow on dead hardwood trees in a warm, moist environment. A combination of warm temperatures and high rainfall induces increased growth of shiitake mycelium, from which the mushrooms grow.
    Individually and In Groups - Shiitake mushrooms grow individually at first and in cluster groups as the yield increases with time.

    How To Pick Shiitake Mushrooms


    Appearance - Fresh shiitakes have large, dark-brown, umbrella-like caps with relatively slender, cream-colored stems. Your mushrooms should have a meaty texture and earthy complexion.
    Use A Sharp Knife - Make sure to cut the stem close to the cap carefully with a sharp knife.
    Keep Dry and Clean After Cutting - Ensure you don't bruise or soften you shiitakes since damaging them makes them rot quickly.

    Why Are Shiitake Mushrooms So Popular?



    Medicinal and Nutritional Benefits - Shiitake mushrooms offers some of the most beneficial health and medicinal benefits of any edible mushroom species. Shiitakes usage dates back to Medieval China, shiitakes helped prevent the common cold, increase energy, and ward off hunger.
    Rich in Vitamins - Shiitakes are a source of vitamins A, B2, B12, C, and D, calcium, copper, iron, selenium, manganese and zinc. Shiitake intakes boost your immune system, help you shed weight, offer optimal energy levels, boosts heart health, and inhibits microbial organisms.
    Time Frame - Because of their popularity, shiitakes grow all-round the year in controlled conditions in countries like China, Japan, Taiwan, the US, and Korea. Naturally, they thrive in East Asia during the spring and autumn seasons.
    Fairly Easy To Cultivate - Compared to other mushroom species like morels, shiitakes cultivation is fairly easy. This is also the reason they are the second most cultivated mushrooms after button mushrooms.
    Affordability and Taste - Shiitake mushrooms taste great with numerous recipes and cost less ($5-7 per pound) compared to other mushroom species like the chanterelles ($224 per pound), truffles ($3,600 per pound) and morels ($254 per pound).

    How To Tell If Shiitake Mushrooms Have Gone Bad

    Sight - Look for puckering and wrinkles on the cap and stem skin. These indicate that your mushrooms lack internal moisture, hence past their prime time (link). 
    Touch - Press your finger on the mushroom top and release. If it remains pushed in, your mushroom is going bad. If it bounces back, your mushroom is still fresh (link).
    Smell - Examine your shiitake mushroom for signs of slime, a smelly liquid that indicates your mushroom is decomposing.

    Cleaning Shiitake Mushrooms


    For longer preservation, avoid cleaning or rinsing your shiitakes until just before use (link).
    Dry Method - Gently shake off as much dirt as possible. Avoid too much shaking to prevent breakage, inspect for more dirt and possible breakage.
    Wet Method - Soak your shiitakes in a bowl of salty water, delicately remove any dirt, carefully drain and rinse your mushrooms. Allow them to lay on a kitchen towel for a few minutes to dry.
