Latin Name: Lepista Nuda Common Name: The Blewit, Clitocybe Nuda, Tricholoma Nudum Natural Habitat: Commonly occurring in the summer to late fall across much of the temperateregions of North America and Europe. This species is found in and around decomposingpiles of sawdust, in conifer duff, amongst leaves and in mature compost piles. Fruiting Substrates: Horse manure/straw compost mixed with 10% fresh straw at spawning; leaf mulch/sawdust mixtures. Growing Parameters Spawn Run: Relative Humidity: 90 + %. Substrate Temperature: Fastest growth at 70-75 °F. Temperature maxima and minima: 40 DF. and 86 °F. respectively. Duration: 25-60 days for complete colonization. C02: 5000-10,000 ppm. Fresh Air Exchanges: 0 per hour. Type of Casing: Standard peat based casing. An option is the addition of shredded leaf material and activated charcoal to 10% of total mass. Balance to a pH of 7.0. Primordia Formation: Relative Humidity: 95%. Air Temperature: 55-65 °F. Duration: 7-14 days. C02: less than 1000 ppm Fresh Air Exchanges: 2-4 per hour. Light: Ambient natural light or optimally 10 lux in the 370-420 nanometer range. (Light requirements have not yet been established for this species, and until that time, light stimulation should be presumed as a prerequisite for fruiting.) Notes: The fruiting mechanism may be controlled by bacterial flora associated with leaf mulch and the decomposition process. Singer (1963) reported that mycelium implanted in beds of horse manure/straw compost for 7-14 months produced mushrooms directly after the appearance of rhizomorphs. Wright and Hayes (1979) reported that immature horse manure/straw composts supported the most vigorous mycelial growth, the work of previous researchers indicates that the best fruitings occurred on "spent" compost that has been colonized for a year or more Do not eat raw! This mushroom contains Thermobile Hemolysin, a compound that degenerates red blood cells. The effects are relatively minor and the toxin is easily destroyed by cooking or parboiling. (1980) Harvest while cap is still Convex Mycelium linear to cottony and usually with purplish to violet hues. Good candidate for colonizing and fruiting from spent oyster substrate.

Yeah, I'm looking into the fruit body development parameters right now, but I haven't found anything on it yet. Been looking for a few days. Nothing gives exact measures?
There are a couple of strange details in Stamets parameters, like L. nuda never appears during summer, that 10% addition of fresh straw could never be confirmed by other authors and I am not sure that good old Paul ever saw primordia himself. To find information from successful cultivators, try using french search terms, like 'pied bleu cultiver'. http://troglos.free.fr/dossiers_val_de_loire/dossier_vdl_carriere_champi/chapitre_10/dossier.html http://www.acbx41.com/article-31923831.html Scroll down the second page to see english text in some pics.
