Helotiales

Lachnaceae

Facesoffungi number: FoF 05904
Taxa are mostly saprobic and sometimes plant parasitic. Ascomata are apothecial and characterized by sessile or stipitate, cupulate or discoid receptacle. The margins and flanks are covered with hairs and hairs are cylindrical, septate and sometimes granulate. The ectal excipulum is composed of cells of textura angularis, textura prismatica or textura oblita and medullary excipulum is composed of cells of textura intricata or textura oblita. Paraphyses are filiform, lanceolate or rarely cylindrical. Asci are 8-spored, cylindric-clavate, amyloid or non-amyloid and sometimes arising from croziers. Ascospores are globose, ellipsoid to filiform or allantoid, septate or aseptate, hyaline and guttulate (Jaklitsch et al. 2016, Guatimosim et al. 2016, Chlebicki 1990, Šandová et al. 2018, Suková 2005, Perić & Baral 2014, Ye et al. 2006, Hosoya et al. 2010, Zhuang & Yu 2001, Han et al. 2014). Asexual morphs are pycnidial and conidia globose and aseptate (Jaklitsch et al. 2016).
Notes – Our phylogeny shows the genera Lasiobelonium, Trichopezizella, Solenopezia and Trichopeziza, which were previously classified under Lachnaceae, are not genetically related to this family. Similar phylogenetic placement of these genera was shown in the phylogenies of Guatimosim et al. (2016) and Pärtel (2016). Therefore, considering previous literature and results from our phylogeny, we remove these genera from Lachnaceae.
