Fig. 1. Oleoguttula mirabilis (CBS H-23122 CBS 136102=CCFEE 5523; re-drawn from Egidi et al. 2014) a Phialides with wide openings and very short collarettes and conidia aggregating in dense clusters at phialide tips. Scale bars: a–c = 10 μm.


Importance and role

Importance of genus to ecosystem

Species of Oleoguttula are Rock-inhabiting fungi (RIF).  Oleoguttula is one of the very few sporulating rock-inhabiting fungi ecosystem. They possess special characteristics such as cell structure, metabolism, and stress tolerance mechanisms that enable them to survive harsh niches (Ruibal et al. 2009).


Industrial relevance and applications

No industrial application has been reported from Oleoguttula. It is worth however to screen cultures of Oleoguttula as they may produce secondary metabolites.


Quarantine significance

No biocontrol agent has been reported from Oleoguttula.


Biochemical importance of the genus, chemical diversity or applications

No chemical has been yet reported from Oleoguttula. Being rock inhabiting fungi, they may produce important active agents or extracellular polymeric substances (EPS) that enable them to survive harsh environments (Tesei et al. 2012).


Diversity of the genus

Oleoguttula comprises only one species known from rock in Antarctica. Comprehensive studies are needed to discover more species of Oleoguttula.
