Abstract
This paper gives an account of three Asterina species infecting members of the family Myristicaceae, namely, Asterina knemae attenuatae infected the leaves of Knema attenuata, Asterina myristicae infecting the leaves of Myristica sp. and Asterina myristicacearum infecting the leaves of Myristica malabarica. Of these, Asterina myristicae and Asterina myristicacearum are found to be new species. All these three species are described and illustrated in detail and a key is provided to them. Key to all the species of the genus Asterina reported on Myristicaceae is also supplanted to this study.
Highlights
The genus Asterina is represented by about 700 species, characterised by having brown appressoriate mycelium, stellately dehiscing thyriothecium with globose asci and brown uniseptate ascospores
Thyriothecia scattered to 1–3 connate, orbicular to slightly ovate, 150–250μm in diameter, margin crenate, irregularly opened at the centre; asci very few, globose to slightly a
Note: This species stands distinct from all other Asterina species known on the members of Myristicaceae in having 1-3-celled appressoria
