  −
* Produces chronic ongoing granulomatous rumenitis. 
  −
* Difficult to diagnose in life.
  −

=====Gross=====
  −
  −
* Thickening and ulceration of mucosal surface of [[The Rumen - Anatomy & Physiology|rumen]].
  −
** Feels like thick leather. 
  −
*[[The Rumen - Anatomy & Physiology|Rumen]] wall becomes fibrosed.

  −
=====Histological=====
  −
  −
* Classical granulomatous inflammation
  −
** May have giant cells in addition to sheets of [[Macrophages - WikiBlood|macrophages]].
  −
* Can visualise fungal hyphae in tissue using special stains (PAS),
  −
** Often grow along blood vessels.
