Necrobiosis is the physiological death of a cell, and can be caused by conditions such as basophilia, erythema, or a tumor. It is identified both with[1] and without necrosis.
Necrobiotic disorders are characterized by presence of necrobiotic granuloma on histopathology. Necrobiotic granuloma is described as aggregation of histiocytes around a central area of altered collagen and elastic fibers. Such a granuloma is typically arranged in a palisaded pattern.[2]
It is associated with necrobiosis lipoidica and granuloma annulare.
Necrobiosis differs from apoptosis, which kills a damaged cell to protect the body from harm.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
