ABSTRACT

A dematiaceous Hyphomycete collected on Ixora leaf litter from India is described. The fungus produces two types of conidia: lenticular and selenoid, both typically bivalved with a germ slit, blastic, solitary, terminal on the conidiophore and its successive sympodial proliferations. It is conspecific with the Tanzanian collection of a fungus assigned by Pirozynski in 1972 to Rhinocladiella critaspora Matsushima and designated the holotype of a new species of Pseudobeltrania, P. selenoides, by de Hoog in 1977. Pseudobeltrania selenoides is made the type of a new genus Ardhachandra; Rhinocladiella critaspora Matsushima (= Pseudobeltrania critaspora (Matsushima) de Hoog) is transferred to Ardhachandra as A. critaspora (Matsushima) comb. nov.

An undescribed Hyphomycete occurring on leaf litter of Glycosmis cochinchinensis Pierre, collected at Tambaram, near Madras, India, is described and assigned to a new genus Sopagraha as a new species S. sibika.

Studies on the pollen and spore deposition pattern in the moss cushion is one of the important parameters in the assessment of aerospora of a particular region. The samples of moss cushions were collected from various parts of the tropical dry evergreen forests of Madras Christian College, Chennai, between December 2007 and February 2008. The pollen and spore analysed from moss cushions samples revealed a total of 17 pollen types of Tropical Dry Evergreen forest taxa and fungal spores such as Alternaria, Curvularia, etc. In this study, the concentration of modern pollen taxa is dominant than the fungal spores during the month of January and February when compared to sample analysed during December. This data signifies the relationship between the pollen and spore deposition pattern during this period of the year.
