seldom confluent, elliptical, 1 mm. long, reddish-orange, pulverulent, surrounded by the
ruptured epidermis. Spores globose or subglobose, 38-41 mmm. diam.; epispore hyaline,
closely and finely echinulate, 1 mmm. thick, cell-contents orange-yellow, granular; germ-pores scattered, numerous (12-18), conspicuous; mixed with and partially surrounded by numerous hyaline, capitate paraphyses.
