sympatric specification in the genus Psilocybe

I was just wondering what people thought about the reasons why the majority of Psilocybe species around today are the result of sympatric specification rather than allopatric specification. The first is where one species has such significant variables within its own makeup in one location that it becomes two distinct species as a response to an environmental variable. The later is where one species becomes geographically isolated and evolve in seperate environments. If we are to accept that many of the woodloving psilocybes in the United States and Australia are representations of species from either southern america (weilli? Baeocystis?) or Europe (cyanescens and allies), we would have to concede that their breakup into seperate catagories (azurescens, bohemica, subaeruginosa, cyanescens, eucalypta (?) ) would possibly be a result of sympatric specification (where cyanescens broke into azurescens and cyanescens in the US, or into cyanescens and bohemica in europe or once it became subaeruginosa through geographical isolation, became subaeruginosa and eucalypta (if we accept there differences here for a moment))
The big question is what kind of factors would produce sympatric specification in on geographical region??

would you consider then that Psilocybe eucalypta is a phenotype of subaeruginosa given that it is found on the same substrates and in the same conditions, yet demonstrates quite different macroscopic characteristics that are stable even when grown next to and around the other phenotypes and much less remarkable cystidia and spoer size differences?? Or would it represent specification?

Great post - as Pluteus points out - i didnt really have a forum for it, so thought here would be the most suitable. And you guys have all raised some great points. I suppose we might be looking at a scenario where one entity has a number of variable phenotypes, and for perhaps some reason - a type of lignin in the substrate, two phenotypes could emerge that bend the species stick just that little bit too far. Its interesting when you read that some mycologists in austalia assume that Ps.subaeruginosa is actually just a phenotype of Ps.cyanescens that may have been imported into australia from europe or the us on wood mulch or plant material. They are quite similar, and Guzman's comment that subaeruginosa is associated with naturla patches of rainforest isnt correct - it is like most woodloving psilocybes - cropping up in disturbed and human-created environs.

any one have the means to conduct a compatibility / isozyme test/comparison? I had a guy in Canada doing it, but he hasnt replied for a while.

Without spore dispersal we would be looking at an endless supply of clones?? Or maybe we all have it wrong, and Terence McKenna's intergalactic spore travel and innoculation is the real story

Excellent - youve made my day! I can send you spore prints from various areas (ill have to try and obtain a local one as for some reason i didnt keep that) and try and get some plates going of each so that you have live material to work with (i assume this would be much easier than from dried year-old specimens?? Thanks again. Let me know what you'd like

sorry for my delay in replying - im rather ill at the moment. I will endevour to send Pluteus the specimens as soon as i am able to. Looking forward to it - always get sick with the worst timing.
