Clandestine Freemasonry refers to Masons who are not regular or recognized by the Mainstream Masonic Grand Lodge in whose jurisdiction they reside. Grand Lodges In the United States generally claim jurisdiction over the entire state that they belong to. For example the Grand Lodge of Texas is the highest masonic authority in the state of Texas, however, any mainstream regular blue lodge that is located in any other state or country would not belong to this particular Grand Lodge. To verify if a particular lodge belongs to one of the recognized Grand Lodges, please check on the type of masonic lodge it is. This can be done by looking at the type of lodge that it is. For example, in Texas local lodges have the A.F.&A.M. destination in their names. Other jurisdictions might be called F.&A.M. or F.A.A.M..
