Frisch, Andreas, Ohmura, Yoshihito, Holien, Håkon & Bendiksby, Mika, 2022, A phylogenetic survey of the ascomycete genus Arthrorhaphis (Arthrorhaphidaceae, Lecanoromycetes) including new species in Arthrorhaphis citrinella sensu lato, TAXON 71 (5), pp. 936-962 : 952

Arthrorhaphis catolechioides (Obermayer) Frisch, Y.Ohmura , Holien & Bendiksby, comb. & stat. nov.

≡ Arthrorhaphis citrinella var. catolechioides Obermayer in McCarthy, Fl. Austral. 58A: 226. 2001 – Holotype: AUSTRALIA. Tasmania, Tarn Shelf, Mt Field, 18 Dec 1971, Bratt 71/1696 (HO n.v.).

MycoBank 842544

See Fig. 7A for an image of the species.

Notes. – For a description of this taxon, see Obermayer (2001). Our sequenced specimen agrees well with the protologue ( Obermayer, 2001). The isolated position in the Arthrorhaphis citrinella s.l. clade ( Fig. 4 ) warrants recognition at the species level. Arthrorhaphis catolechioides is currently only known from Australasia.

Specimens examined. – NEW ZEALAND. Canterbury, Arthurs Pass National Park, Temple Basin above the pass near the ski area , 6 Feb 1964, Wetmore 12454 ( MIN 872107 ); Wellington, Tongariro National Park , Taranaki Falls , 7 Apr 1992, Moberg & Owe-Larsson NZ2:5 ( UPS-L-106737 ) .

Fig. 4. Partial representation of the Bayesian 50% majority-rule consensus tree from analysis of MSA-2, showing the Arthrorhaphis citrinella s.l. clade. Branches supported by BPP ≥ 0.95 and ML BS ≥ 70% are indicated by bold black lines; branches supported only by ML BS ≥ 70% are indicated by thin double lines. Numbers in brackets represent clades discussed in the text. Character states: 1 Life form: juvenile parasitism absent (light green), present (reddish brown), missing data (white). 2 Thallus areolae: present (yellow), absent (white); 3 Soredia: citrinella type (turquoise), farinosa type (light green), vulgaris type (dark green), absent (white); 4 Medulla: pale yellow (yellow), cavity (grey), absent (white); 5 Ca-oxalate crystals: absent (white); 6 Ascospores: citrinella type (blue), absent (white). Graphical representation of species delimitations in bGMYC, bPtP, and bP&P: Colours represent delimited species for each species delimitation analysis independently, but have been selected to highlight delimitations congruent across analyses. White represents missing data. The colouring scheme applies only to the current figure.
