#fungioftheskyislands


Fungi in the Sky Islands Course. Hosted by the Southwest Research Station in the Chiricahua Mountains of Southern Arizona, not a place many people would think about for mushrooms. However this unique geological formation contains a diversity of fungi, most drastically adrift from the rest of their populations. We used the Bio-Rad Fish Barcoding with some Fungal ITS primers to generate DNA sequence for vouchered specimens. Educators from NY to CA attended, learned these techniques all the while contributing to new scientific knowledge about what species of mushrooms can be found in Arizona. 1) Tylopilus rubrobrunneus is an excellent example of the disjunct populations of fungi in the Chiricahua. The map shows it’s known distribution (iNaturalist data) and the pin is where this was found and confirmed with DNA sequence. The distribution hints at a time long ago when a continuous oak forest ranged from the east coast down into Mexico and Arizona.

The majority of these also produced useable DNA sequence 10) view from the research station .. .. ..   #dnasequencing     #fungibarcoding     #mushrooms     #mushroombarcoding     #swrs     #fungi     #mycology     #dna     #biotech     #chiricahuamountains     #arizona     #biotecheducation     #citizenscience     #fungioftheskyislands     #Az     #science     #desertfungi     #desertmushrooms     #pcr
