Minutoexcipula Calatayudii
''Minutoexcipula'' is a genus of lichenicolous fungi, lichenicolous (lichen-dwelling) fungi of uncertain family (biology), familial placement in the order Chaetothyriales. It has eight species. The genus was circumscription (taxonomy), circumscribed in 1994 by M. Violeta Atienza Tamarit and David Leslie Hawksworth, with ''Minutoexcipula tuckerae'' assigned as the type species. The genus is characterized both by its black convex -like , as well as the well-differentiated on these structures.

Host (biology)
In biology and medicine, a host is a larger organism that harbours a smaller organism; whether a parasite, parasitic, a mutualism (biology), mutualistic, or a commensalism, commensalist ''guest'' (symbiont). The guest is typically provided with nourishment and shelter. Examples include animals playing host to parasitic worms (e.g. nematodes), cell (biology), cells harbouring pathogenic (disease-causing) viruses, a Fabaceae, bean plant hosting mutualistic (helpful) Rhizobia, nitrogen-fixing bacteria. More specifically in botany, a host plant supplies nutrient, food resources to micropredators, which have an evolutionarily stable strategy, evolutionarily stable relationship with their hosts similar to ectoparasitism. The host range is the collection of hosts that an organism can use as a partner. Symbiosis Symbiosis spans a wide variety of possible relationships between organisms, differing in their permanence and their effects on the two parties. If one of the partners in an ass ...
