This is another beautiful fern with smooth texture. The fronds are fresh green. These ones grow to be about half a meter generally. Please help with the ID.

ferns always wise to take pics of the spores on the reverse of the older fronds

Thank you … I sometimes, but not always, take the picture of the spores. Does the shape/colour of the spores help in identification too?
For these, I will try and find the spores today.

yes. our fern expert … always wants to see the spores/sporangia

I hope this is the same fern I had sent before. It was more difficult to find spores on this one. Most plants, perhaps, are young at the moment.

This is Pteris aspericaulis

Again Dr Chris had helped in identifying this as Pteris aspericaulis.
I have now better photographs and a few ID points;
Pteris aspericaulis

This is a common fern averaging about 50cm long. The stalk is thin, claret coloured, slightly hairy at the base but mostly smooth up 
The long pinna at the apex (though not exclusive to this fern) is conspicuous. In this sample it was about 9 cm long.
The bottom pinnae (usually the bottom two pairs) have extra wings branching out. Pinnules are simple and have no teeth on the edges.
Sori are brown, long and aligned to the edges
The young ferns are light green and can have pink edges.

NIce, … and thanks for following up on what … told us..
good for future photography


How’s this for Taphrina infection!?: (Mixed thread): 2 images.
I just came across my photo of a really heavy infection of the ascomycete fungus, Taphrina laurenciana, which produces small leaf-like galls in compound Pteris species in N.E. and S. India in high rainfall areas. As it causes much confusion, I thought it might be of general interest.
The poor old Pteris under attack is P. aspericaulis (CRFJ 26152, Field no. 2130), from N. of Pokhara, Nepal. Fortunately there is no Taphrina humanifestans in existence despite al the modern horror-films that seem to like the idea!
Please show the label as well.
