“…Comments This species was fully described and illustrated in Samuels et al (2000). Bezerra et al (2003) described Hypocrea stromatica Bezerra et al as the teleomorph of T. stromaticum. We have observed perithecia in Clade B and C (Fig 1e) but not in unresolved Clade A, which includes the ex-type culture (TVC=G.J.S.…”

“…de Souza et al (2006) found that a large collection of strains of T. stromaticum from Brazil, Ecuador and Colombia could be divided between two amplified fragment length polymorphism (AFLP) groups that correlated with a number of biological differences (de Souza et al 2006;2008;Loguercio et al 2009a, b) and the fact that a Hypocrea teleomorph, H. stromatica JL Bezerra et al (Bezerra et al 2003) is known for Group 2. These differences suggest that T. stromaticum as it is currently understood is composed of at least two cryptic species.…”

Trichoderma stromaticum, T. rossicum and newly discovered species form a unique lineage in Trichoderma. Phylogenetic and phenotypic diversity in Trichoderma stromaticum are examined in the light of reported differences in ecological parameters and AFLP patterns. Multilocus phylogenetic analysis using 4 genes (tef1, rbp2, cal, chi18-5) did not reveal phylogenetic basis for the two reported divergent AFLP patterns or for ecological parameters; however, this analysis does indicate incomplete speciation with one supported clade derived from within T. stromaticum that corresponds to AFLP Group 2 of de Souza et al. (2006, Phytopathology 96:61-67). Trichoderma stromaticum is known only from tropical America and is typically found in association with Theobroma cacao infected with Moniliophthora perniciosa. It is reported here for the first time on pseudostromata of M. roreri in Peru. Strains of T. stromaticum also have been isolated as endophytes from stems of Theo. cacao. There are no recognized close relatives of T.stromaticum in tropical America. The closest relatives of T. stromaticum are collected in Africa and Thailand; somewhat more distantly related are T. rossicum and T. barbatum, both found in north temperate regions.

A chronology is presented that charts the development of a genus and species concept in Trichoderma. Eighty-nine species of Trichoderma have been named, and several species of Hypocrea have been linked to unnamed Trichoderma anamorphs. Eighty-three taxa of Trichoderma and their teleomorphs, Hypocrea spp., have been included in phylogenetic analyses, including 11 species of Hypocrea with unnamed Trichoderma anamorphs. Phylogenetic analyses show that Trichoderma and Hypocrea are congeneric. Trichoderma species not linked to Hypocrea teleomorphs are derived from among species that are linked to teleomorphs, indicating sexual and asexual lineages are not independent of each other. Many more species remain to be discovered and described. Molecular phylogenetic analyses have revealed the existence of more species than have been recognized on the basis of morphology alone. A suggestion is made to modify the International Code of Botanical Nomenclature to enable adoption of a single generic name for Trichoderma/Hypocrea, with Trichoderma being the older and more utilitarian name. As increasing numbers of species are studied, the few morphological characters of anamorph and teleomorph have reached their limit for defining species. DNA-based characters have assumed an indispensable role. Exploration of new niches, such as within tree trunks and new geographic locations, have resulted in a substantial increase in the number of species of Trichoderma. Trichoderma is usually considered a genus of free-living soil fungi but evidence suggests that Trichoderma species may be opportunistic, avirulent plant symbionts as well as parasites of other fungi. Members of the genus Trichoderma are universally present in soils, although individual species may be either cosmopolitan (e.g., T. harzianum) or limited (e.g., T. viride) in their geographic distribution. To facilitate identification of species, a list of correctly identified strains of Trichoderma and their GenBank numbers for sequences of translation-elongation factor EF-1alpha and internal transcribed spacer rDNA is provided.

“…For instance, trichostromaticins A -E [14] may contribute to the potent bioactivity of Trichoderma stromaticum [68] (teleomorph: Hypocrea stromatica [69]). Hyperparasitic strains of this species that is known as a biologically active cacao endophyte have successfully been introduced in field control of the causal agent of Witches Broom Disease of cacao (Theobroma cacao) in South America.…”

To date, 18 genera of imperfect and ascomycetous fungi have been recognized to produce ca. 700 individual sequences of peptaibiotics. These are linear polypeptide antibiotics which i) have a molecular weight between 500 and 2,200 Dalton, thus containing 5-21 residues; ii) show a high content of alpha-aminoisobutyric acid; iii) are characterized by the presence of other nonproteinogenic amino acids and/or lipoamino acids; iv) possess an acylated N-terminus, and v) have a C-terminal residue that, in most of them, consists of a free or acetylated amide-bonded 1,2-amino alcohol, but might also be an amine, amide, free amino acid, 2,5-dioxopiperazine, or sugar alcohol. From April 2003 until present, ca. 300 new individual sequences of peptaibiotics have been published in the literature, but most of them have not yet been included in databases. To summarize these new sequences and novel constituents, as well as to introduce fungal species hitherto unknown as producers of peptaibiotics, the relevant literature is reviewed. Furthermore, ecophysiological and taxonomic aspects of the producing fungi are discussed.
