Mushroom varieties #872309

Asked June 09, 2024, 4:35 PM EDT

Hello- I am looking to inoculate fresh Giant Sequoia stump and Norway maple stumps with mushrooms. These mushrooms will not be consumed. I am intending to aid the stumps natural decomposing process without using chemicals. What varieties of mushrooms are typically found on these tree types? Thank you in advance for your time. Thanks Amy

Hi there,

Interesting question! I did a little research and here's what I found...

Giant Sequoia (Sequoiadendron giganteum) - At least 9 fungi have been found associated with decayed giant sequoia wood. The most prevalent are Heterobasidion annosum, Armillaria mellea, Poria incrassata, and P. albipellucida. Armillaria can be a pretty aggressive plant pathogen on a long list of species, so I would advise against using this one. The two Poria species are two species of dry rot. There are lots of other fungal species associated with Giant Sequoia in a mutualistic way, but these would not cause any type of decay.

Norway Maple (Acer platanoides) - Norway Maples are the most commonly attacked trees by the Ganoderma root rot or (Lucidus sp.). The fungal pathogen Ustulina deusta can infect Norway maples, and cause wood decay.

Neither of these species are natively found in the forests of the region I serve in Oregon, so I don't have any direct observational experience with conks/decay fungi on them. I hope this helps, but if not I can try to find someone else who may be able to help more.

Thanks,

Lorelle
