41. Lulworthia opaca (Linder) Cribb et J.W. Cribb, Pap. Dept. Bot. (formerly Biol.) Univ. Qd. 3: 79 (1955)

Substrate and distribution: Marine wood. Bohuslän.

Notes: First reported by Gustafsson and Fries (1956) as Halophiobolus opacus Linder. Also recorded by Eriksson (2014) as Lulworthia opaca from Bohuslän. Since this study was mostly based on material collected by Rolf Santesson at Kristineberg, it probably originates from Bohuslän. Eriksson (2014) also from Bohuslän. See also comment in Tibell (2016), who included this material in Lulworthia medusa .
