Never eat a wild mushroom identified from a website. This one helps you rule things out. It cannot rule anything in.

Pholiota microspora

Never eat a wild-foraged mushroom you identified from a website, this one included. Wild mushroom misidentification can be fatal, and no page can rule a specimen IN. This reference is about cultivated and shop-bought mushrooms only: species you buy, or grow from bought spawn, where there is nothing to identify. To identify anything wild, consult a qualified local expert holding the actual specimen, never a description on a screen.

In the kitchen

Flavour

Mild and nutty with a gentle earthiness.

Texture

Small amber caps under a natural gelatinous coating that thickens a broth; the coating is the point, not a fault.

In the kitchen

A classic miso-soup and hot-pot mushroom in Japan, where its light gel gives body to the liquid. Add near the end and do not rinse the coating away.

How it is cultivated

Substrate

Hardwood logs or sterilised supplemented hardwood sawdust; it prefers cool, damp conditions.

Fruiting temperature

10-16°C (50-61°F)

Humidity

90-95% relative humidity

How it is grown

Hardwood logs, or a supplemented sawdust block

Time to first harvest

A few months on a block; longer on logs

How much, how long

Repeated small clustered flushes

Difficulty at home

Intermediate. Straightforward on sawdust or logs, but it wants genuinely cool, wet fruiting weather.

What is worth knowing about it

One of the most-grown mushrooms in Japan and rarely seen fresh in the West, where it usually turns up canned or vacuum-packed. Its natural gelatinous coat is a culinary feature, prized for the body it lends to soup.
