Mycelial Characteristics: Producing a white, silky, rhizomorphic mycelium, usually exquisitely formed, and growing out in distinct zonations. Mycelium becomes overlain with yellow tones in age but not the rusty brown colorations that are typical of Hypholoma sublateritium.

Fragrance Signature: A fresh, sweet, forest-like, pleasant fragrance, similar to Stropharia rugoso-annulata.

Natural Method of Cultivation: Using nature as a guide and applying the methods used for H. sublateritium, I recommend cultivating this mushroom on stumps. This aggressive species may be one of the best for recycling millions of conifer stumps left in the aftermath of logging. Clusters hosting dozens of fruitbodies and weighing up to four pounds have been collected.

Recommended Courses for Expansion of Mycelial I kiass to Achieve Fruiting: Nutrified agar into liquid fermentation for 48 hours. (The broth used for fermentation should be fortified with 2-5 grams of sawdust per liter.) Once fermented, the liquid inoculum is transferred into sterilized grain which can be expanded two or three more generations. The grain spawn can inoculate sterilized sawdust/

chins but the spawn rate should not exceed 10% (moist spawn/mo-st sawdust). The sawdust/chip back's can be fruited after a restii ? period, or be used for outdoor planting. The yield of this mushroom is not enhanced by bran like supplements. Suggested Agar Culture Media: MEA, PDYA, DFA or OMYA.
