Umbilicaria

Belongs within: Lecanoromycetes.Contains: Umbilicaria section Glabrae, Umbilicaria section Polymorphae, Umbilicaria secton Velleae. Umbilicaria, rock tripe, is a cosmopolitan genus of saxicolous lichens that derive their name from their attachment to the substrate by a distinct ‘navel’. Spores are generally relatively large in members of the subgenus Gyrophoropsis and smaller in subgenus Gyrophora. However, the species U. depressa has smaller spores… Continue reading Umbilicaria

Ostropales

Belongs within: Ostropomycetidae.Contains: Trichotheliales, Gyalectales, Gomphillaceae. The Ostropales are an assemblage of lichenised and non-lichenised fungi, the latter being saprobic on stems, bark or wood (Kirk et al. 2001). Characters (Kirk et al. 2001): Stromatic development usually weak, reduced to intramatrical hyphae, or absent, or with usually crustose thalli. Ascomata more or less apothecial, often deeply immersed and appearing perithecial, with rather… Continue reading Ostropales

Agyriales

Belongs within: Ostropomycetidae. The Agyriales are an assemblage of lichenised and non-lichenised fungi united by a weakly amyloid hymenial gel, basically weakly hemiangiocarpous ascoma development, and asci that open by eversion (Lumbsch et al. 2001). Agyriales [Agyriineae] |–Elixia Lumbsch 1997E99 [incl. Leptographa (Fries) Choisy 1950 non Jatta 1892E99; ElixiaceaeEB03] | `–*E. flexella (Acharius) Lumbsch 1997 [=Limboria flexella, Ptychographa… Continue reading Agyriales

Lecanoromycetes

Belongs within: Ascomycota.Contains: Lecanoromycetidae, Ostropomycetidae, Umbilicaria. The Lecanoromycetes are a diverse clade of fungi, including the greater part of lichenised fungi. Characters (Adl et al. 2012): Ascomata apothecial, discoid, perithecial or elongated, sometimes stalked or immersed, occasionally evanescent; interascal tissue of simple or branched paraphyses swollen at apices, often with pigmented or iodine-staining epithecium; hymenial gel often present; asci not fissitunicate,… Continue reading Lecanoromycetes

Gyalectales

The Gyalectales are a clade of lichenised fungi with functionally unitunicate asci and ascohymenial ascoma development. <==Gyalectales |–CoenogoniaceaeEB03N | |–Petractis Fr. 1845ML04, KC01 | | |–P. clausaML04 | | `–P. luetkemuelleriLK04 | `–Coenogonium Ehrenb. 1820KC01 (see below for synonymy) | |–*C. linkiiEB03N | |–C. disjunctumEB03N | |–‘Dimerella’ epiphylla [=*Didymopycnomyces hyalinus]E99 | |–C. leprieuriiLK04… Continue reading Gyalectales

Lecideaceae

Belongs within: Lecanoromycetidae. The Lecideaceae are a family of fungi lichenised with green algae (Kirk et al. 2001). Characters (Kirk et al. 2001): Thallus crustose to squamulose, rarely absent, with poorly developed rhizoids. Ascomata apothecial, sessile, margin absent or weakly developed, usually domed, light or dark; hymenium blueing in iodine. Interascal tissue of branched or anastomosing paraphyses, usually swollen at apices,… Continue reading Lecideaceae

Teloschistales

Belongs within: Lecanoromycetidae.Contains: Physciaceae, Caliciaceae. The Teloschistales are a clade of lichenised fungi associated with green algae. The Teloschistaceae produce brightly coloured ascomata, usually with a well-developed thalline margin (Kirk et al. 2001). <==Teloschistales [Caliciales, Teloschistineae] |–+–PhysciaceaeSS09 | `–CaliciaceaeML04 `–Teloschistaceae [Caloplacaceae]EB03 | i. s.: Cephalophysis (Hertel) Kilias 1985KC01 | Fulgensia Massal. & De Not. 1853 [incl.

Lecanoromycetidae

Belongs within: Lecanoromycetes.Contains: Stereocaulaceae, Sphaerophoraceae, Teloschistales, Lecanorales, Rhizocarpaceae, Lecideaceae, Peltigerineae, Collematineae. The Lecanoromycetidae are a large clade of mostly lichenised fungi. Most subclades form lichens in association with green algae; species that associate with cyanobacteria are found only in the clade Peltigerales (though most species of that clade are cyanobacteria-associates). Historically, the clade has been… Continue reading Lecanoromycetidae

Caliciaceae

Belongs within: Teloschistales. The Caliciaceae are a group of mostly lichen-forming fungi with stalked, mazaediate ascomata (Kirk et al. 2001). Characters (Kirk et al. 2001): Thallus crustose where present. Ascomata stalked, mazaediate. Asci cylindrical, formed from croziers, thin-walled, evanescent. Ascospores 0- to 1-septate, dark brown, with ornamentation formed from rupturing of outer wall layers, forming a dry mass. Caliciaceae [Cypheliaceae, Tholurnaceae]… Continue reading Caliciaceae

Physciaceae

Belongs within: Teloschistales. The Physciaceae are a family of lichenised fungi associated with green algae, often found growing on nitrogen-rich substrates. A pseudoparenchymatous upper cortex is present in species of the genus Physcia. Characters (Cannon & Kirk 2007): Thallus crustose, foliose or fruticose. Ascomata apothecial, sessile, occasionally immersed, usually with a distinct margin. Interascal tissue composed… Continue reading Physciaceae
