ANIXIELLA AND DIPLOGELASINOSPORA, TWO GENERA WITH CLEISTOTHECIA AND PITTED ASCOSPORES
The genus Anixiella Saito and Minoura is validated with a Latin description. Thielavia reticulata Booth and Ebben is transferred to Anixiella and the species redescribed and illustrated. The globose, blackish perithecia are nonostiolate. The broadly clavate asci are arranged in a fascicle, have a thickened ring in the apex, but are evanescent. These characteristics, along with the dark, pitted ascospores, indicate that this species has evolved from the genus Gelasinospora, which differs in having ostiolate perithecia. The new genus Diplogelasinospora with a single new species D. princeps represents another line evolved from Gelasinospora. As in Anixiella, the dark perithecia are nonostiolate and the cylindrical asci are evanescent. However, the ascospores have a hyaline cell formed at the base by means of a transverse septum.
