Catenulopsora, a new Genes of Rusts

Kuehneola species (Phragmidiaceae, Pucciniales) on Vitaceae plants

“…Basidiospores: obovoid, 6-9×5-7 μm in size; the wall thin, colorless. Thirumalachar (1943) designated the holotype as above and specified another specimen as BDacca, October 7, 1910, leg. A. L. Som.^They indicated the presence of spermogonia on the holotype specimen and a possible demicyclic life cycle of this species.…”

“…The isotype and an additional specimen examined in this study bore no structure like spermogonia. Mundkur and Thirumalachar (1943) included two specimens on Cissus adnata Roxb. collected by E. J. Butler and Inayat in Noakhali, southeastern Bangladesh.…”

“…& Thirum. on Flacourtia (Flacourtiaceae) (Mundkur and Thirumalachar 1943). In the type species, a laterally free, uniseriate multicellular teliospore developed from a teliospore initial arisen from a telial hymenium, from which a teliospore mother cell and a pedicel cell differentiated.…”

“…Subsequently, the teliospore mother cell elongated and became transeversly septate to form a multicellular mature teliospore. Teliospore germination by continuous apical elongation was said to be unique to the genus (Mundkur and Thirumalachar 1943). However, teliospore germination (basidium production) by continuous apical elongation of teliospore cells was proven to be common in Kuehneola.…”

“…This was in contradiction to the descriptions and illustration in Butler (1912) that clearly indicated what Arthur (1917) circumscribed for Kuehneola. On the other hand, Mundkur and Thirumalachar (1943), when establishing Catenulopsora, determined that K. vitis formed a laterally free, uniseriate multicellular teliospore by transverse septation on a pedicel and transferred it to Catenulopsora. This taxonomic treatment was soon replaced by the reclassification of C. vitis in Kuehneola with nomenclatural revision as K. vitis, which name is accepted herein.…”
