I read online that hardwood mulch is preferable for inoculating and growing winecap mushrooms. Why is this?
I got a dump of mulch from a local arborist. Turned out that it is primarily pine which is a softwood. How will it affect the mushroom spawn? Will softwood not colonize as well? Will mushroom yield be lesser/none at all? Will I need to add mulch material more frequently?
The issue with the pine is the sap which impedes the growth of the fungal strands. Chipped wood *might* work, but pine wood that has dried out works better. Maybe if you mix some straw or other chips you could get good results?
I have not had luck with a primarily pine/cedar/conifer chip with winecaps but something that it will devour is a mixture of cardboard and fallen deciduous leaves. You can even utilize hay but be warned that it will be gobbled up quick.
I have found, oddly enough, box elder wood is a favorite of many mushrooms. I do not know what it is but I have had winecaps, elm oyster, golden oyster, and a few other inoculate onto box elder without much issue.
HT Timothy for the tip about box elder. I just cut one down the other day and now I know what to do with it. I saw some native oysters fruiting over the weekend (weird time of year for them but it's a sheltered spot) and that will be a source for spawn.
I don't see any pine sap on the mulch. So fingers crossed. If not winecap, are there other beginner friendly edible mushrooms that I can try to grow in the garden (and get mushroom compost as well in the process)?

You could try wood blewit, I've heard it prefers a mixture of pine/hardwood/leaflitter/scraps. I would recommend experimenting. I'd still give winecaps a try if it were me, its all an experiment anyway!
I wanted to follow up to this post with an update on one of my beds.
I had a 10Lb block left over from inoculating garden beds this past year and it sat in a small fridge of mine for 5 months before I distributed it to my mulched beds.
This is the main bed that I inoculated. Previously, it was grass that required regrading to stop a negative slope towards my basement.
This bed I experimented with utilizing Kraft brown paper in a jumbo roll. This minimizes chemicals utilized in the process of making the paper and skips the bleaching process. I laid it down on top of the grass and secured it with landscaping staples temporarily. I layered compost/topsoil on top and created a sufficient grade by hand due to the presence of my septic pipe being in the area.
The mulch that I used is what is most interesting to me. I had six nasty, oozing, infected, beat-up Siberian elms on my property dropped. They were chipped into a pile of pine and allowed to 'cook' for a few months. This stuff was STEAMING when I dug into it and already had some mycelium running in it. I wasn't convinced that my refrigerated spawn would be able to compete but the proof is in the pictures!
Experiment! Trial stuff! There will be losses but then there will be wins!
I have four more Siberian elms to drop, they will be topping off this bed and with some luck we will see the mushrooms overtake the area!
