Assessment Notes

Taxonomic notes

Beltraniella portoricensis was first recorded by Piroz. and S.D. Patil (1970) who treated Ellisiella portoricensis F. Stevens as a basionym, and transferred it to the genus Beltraniella Subramanian as B. portoricensis (F. Stevens) Piroz. & S.D. Patil. Beltraniella portoricensis has four synonyms, Ellisiella portoricensis, Ellisiellina portoricensis, Ellisiopsis portoricensis and Ellisiopsis gallesiae. The species B. portoricensis has simple or crowned setae and simple or branched, straight or curved, tappering, septate, thick-walled, smooth to verrucose, brown to dark brown, conidiophores macronematous, mononematous, simple or branched, straight or curved, septate, with denticles, smooth, subhyaline to pale brown, conidiogenous cells denticulate, sympodial and conidia oblageniform or pyriform, truncated at the base, smooth, subhyaline to yellowish brown (Pirozynski; Patil 1970; Chen; Tzean, 2009).


Why suggested for a Global Red List Assessment?

The species Beltraniella portoricensis is viewed cosmopolitan and is asssociation with decaying leaf material in forest ground, where there is a large production of organic matter. Yet, in impacted environmets where there is a reduction of vegetation, this species may declive in way sharply.


Geographic range

The taxon is distributed in tropical, subtropical and temperate climate


Population and Trends

Beltraniella portoricensis is widely distributed, found in tropical, subtropical and temperate regions and is commonly isolated from decaying leaves (Pirozynski; Patil,  1970; Sutton, 1980; Heredia; Mercado-Sierra, 1998; Castañeda-Ruiz et al., 2009; Milagres et al., 2018).

Research needed

Although Beltraniella portoricensis is considered cosmopolitan and pantropical, there are no reports of the occurrence of this species in Europe. In Brazil, there is no record of this taxon in mangroves, sandbanks and coastal tablelands.

Use and Trade

Beltraniella portoricensis was effective to control bacterial spot were of bacterial spot of tomato after inoculation with Xanthomonas euvesicatoria in plants treated with saprobe fungi filtrates (Peitl et al., 2017).
Beltraniella portoricensis showed antifungal properties against Alternaria tagetica, Colletotrichum gloeosporióides and antibacterial against Bacillus subtilis and Staphyloccocus aureus in a study with applications in agriculture and pharmacy, in order to know the activity and type of metabolites they present (Reyes-Estebanez et al., 2008; Gamboa-Angulo et al, 2013).
An enzyme (endo-1,4-β-D-glucanase) produced by Beltraniella portoricensis has been purified and is used in the detergent industry as a surfactant (Baba et al, 2005).
