RE: [BRYONET] Fissidens query

These are small tubers –the first image shows large lipid droplets inside the cells. The last image shows that they are produced from rhizoidal side branches cf chytrid galls which are terminal.

The images in the following papers may be helpful.

 

Best Wishes

Dear bryofriends,

 

Happy Christmas and Happy New Year!

 

I came across a tiny Fissidens species from Macao, Southern China. The most peculiar characters are: 1) There are something similar to protonemata developed from rhizoids, I’d like to know if they are protonemata or not? 2) There are some rounded bodies attached on the rhizoids, are they tubers? Four images attached show the details.

 

Any suggestions are welcome.

 

Thanks in advance.

 

Sincerely,

 

ZHANG, Li
