The ellipsoid spored species of pulvinula pezizales

Mycotaxon 20(2): 607-616
The ellipsoid spored species of pulvinula pezizales
The genus Pulvinula Boud. consists primarily of spherical-spored species. A single ellipsoid-spored species, P. ovalispora Boud., is described and previously reported only from the 1912 type collection from Algiers (Boudier, 1917; Pfister, 1976). That type specimen was reexamined; it is conspecific with 3 North American collections, with one from Jamaica and with one from the Canary Islands. Four ellipsoid-spored collections of Pulvinula were made in China, but these differ sufficiently from Boudier's species to require description as P. ascoboloides sp. nov., with a cyanophilous sheath surrounding the ascospores. Some comments on peculiarities of Pulvinula are appended.
