Paracamarosporium
Paracamarosporium Wijayaw. & K.D. Hyde, Cryptog. Mycol. 35(2): 183 (2014)
Index Fungorum number: IF 550563; Facesoffungi number: FoF 08240, 7 morphological species (Species Fungorum 2021), 7 species with molecular data.
Saprobic on dead branches and stems of Fabaceae (Dicotyledons). Sexual morph: Unknown. Asexual morph: Conidiomata immersed to erumpent, solitary, globose, ostiolate. Ostiole central, single. Conidiomata wall composed of brown-walled cells of textura angularis. Paraphyses hyaline, hyphae-like, smooth, intermingled among conidiogenous cells, sub cylindrical, with bulbous base, tapering to obtuse apex, 1–4-septate, unbranched or branched at base, and anastomosing. Conidiophores reduced to conidiogenous cells. Conidiogenous cells lining the inner cavity, globose to doliiform, hyaline, smooth, phialidic with prominent periclinal thickening and thick channel (at times also with percurrent proliferation). Conidia ellipsoid to ovoid, with obtuse ends, brown, finely roughened, 1–3 transversely septate, developing 1–6 oblique to transverse septa, at times becoming constricted at primary septa. Microconidiogenous cells intermingled among macro conidiogenous cells, hyaline, smooth, ampulliform to doliiform to irregular, mono to polyphialidic, proliferating percurrently, or with periclinal thickening. Microconidia hyaline, smooth, guttulate, bacilliform to sub cylindrical, apex obtuse, base truncate (Adapted from Crous et al. 2013)
Type species: Paracamarosporium psoraleae (Crous & M.J. Wingf.) Wijayaw. & K.D. Hyde
Notes: Paracamarosporium was introduced by Wijayawardene and Hyde (2014) with P. psoraleae as type species. P. psoraleae was previously known as Camarosporium psoraleae Crous & M.J. Wingf and was reported as not congeneric with Camarosporium sensu stricto by Wijayawardene et al. (2014d). Paracamarosporium differs from Camarosporium sensu stricto in that it produces microconidiogenous cells while Camarosporium sensu stricto does not have microconidia stage. Paracamarosporium also resembles Pseudocamarosporium in having pycnidial conidiomata, enteroblastic and phialidic conidiogenesis with percurrent proliferation and muriform conidia (Wijayawardene et al. 2014c). Paracamarosporium differs from Pseudocamarosporium in having hyaline, smooth-walled, guttulate, bacilliform to subcylindrical microconidia (Wijayawardene et al. 2014c). Paracamarosporium is phylogenetically a distinct and well-supported lineage grouped in Didymosphaeriaceae.
