“…In addition, there is precedent for provisionally treating species as members of historically heterogeneous genera awaiting phylogenetic and taxonomic clarification, recent examples being, e.g. Lecidea coriacea Holien & Palice (Holien et al 2016), Bacidia gullahgeechee Lendemer (Lendemer 2018), Bacidia pruinata Fryday (Fryday 2019) and Lecidea streveleri T.

We discuss the taxonomy of three species of Bacidia occurring in insular Laurimacaronesia. Two of them, B. amylothelia (Vain.) Vain. and B. endoleucoides (Nyl.) Zahlbr., which were previously described from Angola and Madeira, respectively, are found here to belong in Bacidia s. str. (Ramalinaceae). Modern descriptions and illustrations are provided for the first time. Bacidia amylothelia is similar to B. areolata Gerasimova & A. Beck, B. campalea (Tuck.) S. Ekman & Kalb, B. fusconigrescens (Nyl.) Zahlbr., B. heteroloma (Vain.) Zahlbr., B. millegrana (Taylor) Zahlbr. and B. suffusa (Fr.) A. Schneid. and is reported here from the Canary Islands. Bacidia endoleucoides is most likely to be confused with B. absistens (Nyl.) Arnold, B. friesiana (Hepp) Körb., B. salazarensis B. de Lesd. and B. caesiovirens S. Ekman & Holien and was found to be widely distributed in the Canary Islands and Azores in addition to Madeira. The third species, Bacidia deludens S. Ekman, Tønsberg & van den Boom, is described here as new to science. Bacidia deludens is characterised by a greyish, crustose thallus with whitish soralia, pale apothecia with crystals in the hymenium and proper exciple, acicular ascospores with 3–19 septa, and the production of fumarprotocetraric acid as the consistently present major substance. It is described here from the Canary Islands and Madeira. Although conservatively treated here in Bacidia, we argue that it is likely to belong in the Malmideaceae. An identification key to all known species of Bacidia s. str. in insular Macaronesia is provided.

“…Several additional poorly known lecideoid lichens, mainly boreal taxa, which are morphologically close to 'L.' plebeja (e.g., 'Lecidea' malmeana complex or 'Lecidea' consimilis) likely belong here as well (Printzen 1995;Holien et al 2016;Palice et al 2018). It was hypothesized that also an enigmatic sporodochial genus Xyleborus, an Appalachian endemic, is a member of this family (Muggia et al 2017).…”

Lichen-inhabiting fungi are highly specialized mycoparasites, commensals or rarely saprotrophs, that are common components of almost every ecosystem, where they develop obligate associations with lichens. Their relevance, however, contrasts with the relatively small number of these fungi described so far. Recent estimates and ongoing studies indicate that a significant fraction of their diversity remains undiscovered and may be expected in tropical regions, in particular in hyperdiverse fog-exposed montane forests. Here, we introduce the new genus Zhurbenkoa, from South America and Europe, for three lichenicolous fungi growing on thalli of the widespread lichen genus Cladonia (Lecanorales). Phylogenetic analyses based on combined sequence data of mt and nuc rDNA obtained from Andean populations (Bolivia) placed Zhurbenkoa as a member of Malmideaceae, a recently introduced family of lichen-forming fungi in the class Lecanoromycetes. Zhurbenkoa is closely related to the genera Savoronala and Sprucidea. The new genus is characterized by the development of grayish brown to almost black apothecia lacking an evident margin, an epihymenium interspersed with crystals (often seen as pruina), a strongly conglutinated hymenium made of noncapitate and sparsely branched paraphyses, a colorless exciple composed of radially arranged hyphae, a Lecanora/Micarea-like ascus type, and aseptate or 1-septate ellipsoidal colorless ascospores. Zhurbenkoa includes two Neotropical (Z. cladoniarum, Z. latispora) and one widespread (Z. epicladonia) species. The lichenicolous trophic mode is documented for the first time in the Malmideaceae, which until now included only lichen-forming associations between fungi and green algae.

“…New species of lichens and lichenicolous fungi continue to be documented and described from North America at a remarkable rate (Allen & Lendemer 2015, Allen & McMullin 2015, Brodo & Lendemer 2015, Brodo & McCune 2017, Carlberg 2016, Cestaro et al 2016, Cornejo et al 2017, Driscoll et al 2016, Esslinger 2017, Fryday 2017, Gasparyan et al 2017, Guzow-Krzeminska et al 2017, Holien et al 2016, Knudsen et al 2016, Lendemer 2016, Magain et al 2016, McCune & Lumbsch 2017, McCune et al 2018, Morse & Ladd 2016, Muggia et al 2015, Muscavitch et al 2017, Myllys et al 2016, Peterson & Goward 2016, Sanders & Lücking 2015, Seavey et al 2017, Tønsberg & Goward 2016. As a result, the number of taxa reported from North America north of Mexico has steadily increased over time, and now stands at 5561 (Esslinger 2018).…”

Studies in Lichens and Lichenicolous Fungi -No. 22: The identities of Lecidea deminutula, L. olivacea var. inspersa, L. virginiensis and Thelenella humilis JAMES C. LENDEMER!, RICHARD C. HARRIS? AND R. TROY MCMULLIN?ABSTRACT. -Notes on four taxa are presented as part of an effort to resolve the taxonomic status of neglected crustose lichen names based on material from North America. Lecidea deminutula, described from non-calcareous rocks in the Great Smoky Mountains of Tennessee, is placed in synonymy with Lecidella enteroleucella. Lecidea olivacea var. inspersa, described from hardwood bark in the Great Smoky Mountains of Tennessee, is placed in synonymy with Lecidella elaeochroma. Lecidea virginiensis, described from seeping, non-calcareous rocks in West Virginia, is lectotypified and placed in synonymy with Bryobilimbia ahlesii. Thelenella humilis described from non-calcareous rocks in New York is placed in synonymy with Protothelenella corrosa.
