Does gravity affect direction of growth?

One of my logs began pinning much faster than the others. Most of the mushroom clusters were well formed before I moved it into the fruiting chamber. The log was lying on the floor during inoculation, and was then hung vertically when moved. I need to upload a picture but all of the mushies seem to have collapsed in on themselves. I'm wondering if this was because the log was flipped so far along into their development.

Mushrooms grow towards light and fresh air.

they only rely on gravity if other stimuli is missing or inadequet.
i.e on wind or light missing, they will use gravity and grow straight up.
add light this changes.
a light below the tub and fruit curve towards the light.
and with only wind they grow with stipe into the wind. think about mush that stretch to the holes... its not searching for fresh air they are altering with the flow that goes through it!! the air movement not freshness!!
mushrooms dont need fresh air to survive... its not about getting oxygen its about removing co2 that is dangerous!!
myc will survive in very very very low oxgygen fact they hardly need it. but they cant take co2 just like us!
survival is more about getting rid of co2 than adding oxygen imo
think in jars there is little oxygen ever..the reason we have GE is to stop the co2 build up(to toxic level) and mainly to stop pressure build up. pressure build up makes extra heat. squeezing a gas makes heat. too much heat will kill myc. and second pressure messes with the active transport in the myc. it relys on a working pressure/ set range of turgor ect so pressure will stall the myc.
this is also 1 reason why they live at set altitudes in nature!!
infact you can abuse them and make them spiral with fan and light lol
curiously and i have a theory on it lol
before spores drop a recurvature happen to align the caps for spore deposits using light and gravity.( a sign of swap from geo- to phototropic responses at this time in the cycle)
this dosent happen with sporeless mutants and most albinoids.(you see the link with light and spore functions )
albinoids maybe as a lack of radiotrophic pathways from no melanin to activate this behaviour.
and normal caps contain the most pigment and they seem to correct the diection the cap faces to make sure they face the correct way for spore load delivery into air currents.
an upside down cap is not as efficient you see. also the cap shape itself lends to the entrainment of air current around and under the cap!
thats why mushrooms that grow in differing habitat have different shapes from flat polypores to our opposite like the liberty cap and other grassland species!
each tailor made for its job of entraining air current s for efficient spore delivery!
so yes gravity plays in a trio with light and wind/air but when any are removed the responsability shifts to the remaining stimuli

just like we use eyes , nose and ears to survey our surroundings, and if 1 is missing the others take the responsability
