Three resinicolous North American species of Mycocaliciales in Europe with a re-evaluation of Chaenothecopsis oregana Rikkinen

Stuck in time – a new Chaenothecopsis species with proliferating ascomata from Cunninghamia resin and its fossil ancestors in European amber

“…However, in this species the stipes tend to branch lower and hence have longer branches and less confluent apothecial heads than in C. nigripunctata. Also the related C. montana Rikkinen can produce branched ascocarps, but more rarely than the other two species (Tuovila et al 2011b).…”

“…In the Mycocaliciales Tibell & Wedin (Eurotiomycetes, Ascomycota) some 10 % of the approximately 150 known species grow on plant exudates (Tibell and Titov 1995;Rikkinen 1999Rikkinen , 2003aTitov 2006;Tuovila et al 2011aTuovila et al , 2011b. Most of these fungi live on conifers and produce perennial, stipitate ascomata on hardened resin and/or resin-impregnated wood.…”

“…The majority of previously known resinicolous mycocalicioid species grow on resins of Northern Hemisphere conifers, especially different species of Pinaceae (Titov & Tibell 1993, Tibell & Titov 1995, Rikkinen 2003a, Tuovila et al 2011b. Species on conifer resin have been described from both Eurasian and North-American boreal and temperate forests.…”

Nomenclatural corrections in calicioid fungi

“…As noted by Tuovila et al (2011), in the holotype specimen of Chaenothecopsis oregana Rikkinen no ascomata of the named species are preserved, but the type still includes those of another, previously undescribed taxon. In other words, the present "holotype" material does not correspond with the species description of C. oregana (Rikkinen 2003).…”

“…In other words, the present "holotype" material does not correspond with the species description of C. oregana (Rikkinen 2003). For this reason Tuovila et al (2011) proposed to discard the species epithet oregana and described both Chaenothecopsis species in question as new. Accordingly, the species present in the original holotype of C. oregana was described as Chaenothecopsis diabolica Rikkinen & Tuovila, and the species corresponding to the original description as Chaenothecopsis zebrina Rikkinen & Tuovila.…”
