A Phoma sect. Phoma .

Abstract

This chapter describes the morphological characters of Phoma spp. section Phoma. A key to the species and varieties under this section is provided, based on in vitro characteristics. The morphology, host plants and geographical distribution of 68 species of the section are tabulated. The possibility of identifying the species belonging to this section in vivo is briefly discussed.

The Genera of Fungi — G 4: Camarosporium and Dothiora

“…Notes : This isolate was deposited as Phoma sp., and reclassified as Coniothyrium carteri (based on Phoma carteri ; see Boerema et al 2004) by De Gruyter et al (2013). However, as shown here, it clusters separately from Coniothyrium s.str .…”

“…see below in the present study), and thus it is almost impossible to clarify the generic identification without molecular data. Furthermore, the treatment of Phoma by Boerema et al (2004) placed genetically distinct genera into one genus, while the same was true for the treatment of Pleospora by De Gruyter et al . (2013), and the assumption that the reference strains of Camarosporium included in Crous et al .…”

“…Notes : Phoma fallens is associated with leaf spots of Olea europaea in Europe (conidia 7–9 × 3–4 μm), while Phoma glaucispora (conidia 5–8 × 2.5–4.5 μm) is associated with leaf spots on Nerium oleander in Europe (Boerema et al 2004). Phylogenetically, however, De Gruyter et al .…”

“…Within Pyrenochaetopsis , P. poae is closely allied to P. leptospora (conidia 4.5–7 × 1–2 μm; Boerema et al 2004) and is best distinguished based on phylogenetic data.…”

“…Notes — Within Phoma section Peyronellaea species were formerly characterised by having dictyochlamydospores and in some cases epicoccum-like synasexual morphs (Boerema et al 2004). In a subsequent phylogenetic study, Aveskamp et al (2009) showed that chlamydospore formation evolved several times within the Phoma complex.…”
