Please find the 3 close up photos (cropped) attached.Hope this'll help you to identify the species.Please provide the classification of this plant as well.

Yes this is also *Cyathodium sp. *but i am waiting for a more close up to have a look on the thallus structure. At this stage of the plant (which the picture depict) its very difficult to find reproductive organs. So only thallus is sufficient to confirm.

all specimens are Cyathodium. 

*The genus Cyathodium is represented by nine taxa in India. They are C. indicum, C. tuberosum, C. mehranum, C. aureonitens, C. tuberculatum, C. cavernarum, C. smaragdinum, C. denticulatum and C. acrotrichum. The genus
is mainly characterized by thin, delicate, hyaline, spongy, dichotomously branched thallus. The female involucre is present on the ventral surface of the thallus towards the apex. The involucre is characteristic, being globose
with a wide, rimmed mouth inhabiting usually one sporophyte. Rarely there may be two sporophytes in one involucre, although C. mehranum usually possesses two sporophytes per involucres. Out of the 9 species of Cyathodium found in India, C. aureonitens, C. cavernarum, C. smaragdinum is having south Indian distribution.* 

Cyathodium caveernarum, Cyathodium denticulatum, Cyathodium smaragdinum are with smooth involucres and C. aureonitens, C. tuberosum, C. mehranum, C. indicum, C. tuberculatum and C. acrotrichum are having hairy
involucre. Cyathodium foetidissimum doses not form distinct rosettes. This plant has an aromatic smell when fresh.

Your plant may be out of the two

If it is a glossy plant then its Cyathodium caveernarum

If it is not a glossy plant then its Cyathodium smaragdinum
