THE GENERIC DISTINCTION BETWEEN CHAETOPSINA AND KIONOCHAETA, WITH DESCRIPTIONS OF 2 NEW SPECIES

Chaetopsina hongkongensis sp, nov. from decaying palm rachids, and Kio nochaeta australiensis sp, nov. from decaying wood submerged in a fres hwater stream, are described and illustrated. Both species produced se tose conidiophores and phialidic conidiogenous cells. The former is di stinct in having polyblastic conidiogenous cells with multiple denticu late loci, and is compared with C. polyblastia. In Kionochaeta austral iensis conidiophores have accessory setiform lateral branches, and it is compared with K. keniensis, K. pughii, and K. ramifera. The delimit ation of these two genera is discussed with additional information pro vided from an SEM study of conidiogenous characters in C. hongkongensi s.
