Life habit: saprophytic or parasitic, non-lichenized Ascomata and conidiomata: unknown mycelium: immersed to superficial conidiophores: superficial, semi-macronematous, brown, occasionally branched at the base conidiogenous cells: brown, integrated, terminal, monoblastic, determinate, cylindrical, smooth or verrucose conidia: pale to dark brown, (0-)1- to transversely multi-septate, ellipsoid to doliiform or cylindrical, catenate, rarely solitary, generally straight, often truncate at both ends, smooth or verrucose, often separating with difficulty Geography: cosmopolitan Substrate: on plants, wood and lichens. Notes: Taeniolella is variable, and it is possible that some of the included taxa are not related with the type species. Most saprophytic species have multi-septate conidia, whilst the lichenicolous ones have (0-)1(-2)-septate conidia. Conidia are catenate in most species, but solitary in some. The conidial ornamentation is also variable. Most lichenicolous species are strictly host specific, which represents an invaluable aid in their identification. Often, lichen thalli are overgrown by hyphomycetes similar to Taeniolella species, but appearing not to be host specific, and representing most probably bark saprophytes fortuitously overgrowing weakened thalli; such species are more difficult to identify by lichenologists, as the entire literature on hyphomycetes is needed. Several additional lichenicolous Taeniolella species are known from North America and are likely to be discovered in the Sonoran area.
