I'm listing the English words ending with -ae and formed as the plural of a word in -a of Latin origin. I found in the New Oxford American Dictionary (by alphabetical order):
word American English British English --------------------------------------------------------- algae -dʒi or -gaɪ -dʒiː or -giː alumnae -mnaɪ or -mni -niː amoebae -bi -biː antennae -ni or -naɪ -niː axillae -li or -laɪ -liː ballistae -sti or -staɪ -stiː branchiae -kii or -kaɪ -kiiː bursae -si or -saɪ -siː catenae -ni or -naɪ -niː drachmae -mi or -maɪ -miː exuviae -vii or -viaɪ -viiː

Considering their origin is Latin, the "ae" should be pronounced the 'a' in "master", American English.
Usually words ending in -ae are the plural form form of a word ending in -a, e.g.
puella - girl puellae - girls
Italian, the modern day successor or Latin is using -a and -e for female singular and plural:
ragazza - girl ragazze - girls
But you can clearly see that the pronunciation -e is closer to -ae than -ay.
