Herteliana is a genus of lichen-forming fungi. It contains four species of crustose lichens.

Taxonomy

[edit]

The genus was circumscribed by the lichenologist Peter Wilfred James in 1980.[1] The genus name honours the German teacher and lichenologist Hannes Hertel.[2]

James originally classified the genus in the family Lecideaceae,[2] but it has since been included in the Ramalinaceae (2017),[3][4] and, more recently (2022), in the Cladoniaceae.[5] This is because in 2014, it was shown using molecular phylogenetics that Herteliana taylorii grouped together in a clade with Squamarina, and should thus be excluded from the Ramalinaceae and transferred elsewhere in the Lecanorales; the authors concomitantly recommended resurrecting the family Squamarinaceae (originally proposed by Josef Hafellner in 1984[6]) to contain Herteliana and Squamarina.[7] In 2018, Kraichuk and colleagues proposed to fold the Squamarinaceae into the Cladoniaceae,[8] a taxonomic suggestion that had been accepted by later authors.[3]

The original type species assigned by James, H. taylorii, is now considered synonymous with H. gagei.[9]

Description

[edit]

The thallus (the body of the lichen) of Herteliana is crust-like. The apothecia (fruiting bodies) can be either embedded within the thallus or sit directly on its surface, are spherical (globose), and have a distinct margin. The excipulum (the outer layer of the apothecium) is made up of tightly packed cells that resemble plant tissue (pseudoparenchymatous). The hypothecium(the layer below the spore-producing area) extends significantly and forms a root-like structure, and is nearly colourless.[1]

The paraphyses (sterile filaments within the apothecia) have swollen tips, are mostly unbranched, but sometimes they branch and reconnect. The asci (spore-producing sacs) resemble those in the genus Lecanora and typically contain eight spores. The ascospores are broadly spindle-shaped, simple (not divided by septa), and colourless.[1]

The pycnidia (structures that produce asexual spores) are embedded in the thallus, and the conidia (asexual spores) are formed at the tips, are sickle-shaped, simple, and colourless.[1]
