Döbbeler, P. 2011. Two new hepaticolous species of the genus Octosporella (Pezizales). — Herzogia 24: 357–365.
The pezizalean genus Octosporella (Pyronemataceae, Ascomycetes) is characterized by having orange-coloured perithecia-like ascomata, thick, colourless, superficial hyphae with elaborate infection structures consisting of appressoria and intracellular haustoria, and biotrophic obligate parasitism of hepatics. Two species are described as new. Both occur on hosts not recorded before for bryophilous fungi. Octosporella epiphylla, with spherical ascospores, infects epiphyllous Lejeuneaceae (Ceratolejeunea sp.) in Costa Rica and French Guiana. Octosporella fortunata grows on terricolous Saccogyna viticulosa on the Canary Islands and forms ascomata hidden within the host mats. Octosporella currently comprises ten species.
