Question

what are the various vegetative structure met within lichen thallus​

Answer 1

The ‘vegetative’ part of the lichen is the thallus, and this can develop into a morphologically diverse range of structures: multiply branched tufts, flat, leaf-like structures, filamentous structures, aggregations of tiny plates, thin crusts, layers of powdery granules, or hardly any visible thallus at all. Imposing a classification on this variation inevitably results in uncertain distinctions and borderline cases, but several general growth forms can be recognised. The treatment here matches that in Dobson (2011) and generally that in the multi-author accounts in Smith et al. (2009).

foliose, fruticose, squamulose, crustose, placodioid, leprose, filamentous, no visible thallus

Answer 2

The ‘vegetative’ section of the "lichen is known as thallus", and this can mature into a "morphologically diverse range of structures":

Explanation:

• Expanded branched tufts, flat, leaf-like shape, filamentous shape, aggregations of tiny plates, thin crusts, layers of powdery granules, or hardly any evident thallus at all.
• Imposing a distribution on this variation inevitably produced in the uncertain distinctions and borderline cases, but the various general growth that forms can be identified.
