wondering about Ps. Azurscens

Ok, this just some ponderings I have had about azurescens. They are native to the coast of NW oregon and SW washington. They are classified as a wood loving species, and they do love wood, but there native habitat is dune grasses. Whats weird to me is that they seem to flourish with the non-native dune grass from Europe which now dominates the coast. Has anyone ever searched for them in the dunes of the UK? It seem possible they could have been introduced to the area via the grass. Perhaps they were native to the mouth of the Columbia, growing in the tidal zones off of driftwood and native grasses in the past in small numbers. The native areas where they are found in both oregon and washington have been changed a lot by man, most of the dune areas didn't even exist before man changed the environment by building jetties and introducing the tenacious dune grass. Anyone ever thought about this stuff? Any theories?

remember that they where discovered not in the dunes but in the riparian zones of the columbia, and consider that- as i take it- it is far more likely for a colony of lignicolous fungi to spread downstream than up, as that is the direction of the flows of water, which deposit debris [and by extension, colonized debris] along the banks, amidst other suitable substrata.
P. azurescens may be invasive but i tend towards the belief that it originated upland.

it would be interesting and possibly productive to hypothesize a mechanism or vector by which the organism might travel upstream and by what timeframe. if in fact it originated in the coastal or inter-tidal zones or was introduced there then an establishment of it's mechanism of spread inland [e.g. purely linear growth or another hypothetical vector] then a working epidemic model might be devised and a probable timeline could possibly be speculated.

whoa canid you are a person that always like to read their opinion since not many people see all as a biologist will do, in all your post there is a tendency to get that from you, i can understand mushrooms because all the biology book i have read ,and class that make me understand all thing and live creature i know is a hard job , but an amazing one, full of discovery's all the time, i believe your theory about the ps, azurences may originate up land it sound logic , and i have seem that distribution here,downstream, but is also cool to notice that Gopal said about the introduction of dune grass they seem to love that to , you also mentioned that the area have change in Oregon and the places it grow, i wonders why we don´t see to much pictures of azure's,and more of cyan....----mushrooms are very opportunist, i bet the pnw have the endemic species, maybe azurescens,or other, because of the great woods that have there, in some places the rain is very good and many microclime and cascades and water is ,that mean mushrooms , i believe in the theory that all the wood lover originate in the woods and they now are more commons in the city's but they will go back to the woods more and more , is starting again, it will be interest to see more studies of the borders area of Mexico and USA close to the pnw, that have a different rainy season than all Mexico and more the rainy season of USA and species of plant of USA too, i mean in the woods not in the desert areas, , i have notice some sierra in baja California that are somehow like sierras in the pnw, so the probability that mushrooms with certain genotypes like cyanescens are there are hight ....... the distribution of all mushrooms is changing more faster that in last years ,partly because more studies, more people picking spreading spores , evolution, changes in climate. .now i think that only places with really dry environment or extremely cold are impossible to find psilocybe or actives ones, is like their are spreading or they where there before. hard to say all mushrooms in USA intrigue me , and got lot of my attention.

Thanks for you reply. I agree that a downstream movement makes more common sense, but you don't find them very far up river, not past the tidal areas, at least to my knowledge. So theoretically spores and/or mycelium could have been spread by the tide. I have thought it could be possible they were spread upriver via the building of the jetties, perhaps from barges or the trains used to move the rock. It could just be spore spread in a favorable environment. In fact, the wind often travels in off the ocean so wind spread is always a factor. Its just something I have been thinking about, we will never know.
