Cladia blanchonii Parnmen & Lumbsch , sp. nov. ( Fig. 3A ). Mycobank No.: 803448

Characterized by inflated and tapered sterile pseudopodetia, with glossy, pale yellow to greenish brown surface, mostly dichotomously branched toward the apex. Perforations rare to abundant. Fertile pseudopodetia robust and either inflated or not, and racemosely branched. Perforations abundant. Conidiomata on terminal branches of sterile pseudopodetia, conidia 5–7.5 µm long, bacilliform. Apothecia on short terminal branches of fertile pseudopodetia, 0.5–1.0 mm wide, disk concave to plane, brownish black; ascospores ellipsoid, non-septate, hyaline, 6.25–7.50 × 2.5 µm, 8 per ascus. Secondary chemistry: Barbatic acid and 4- O -demethylbarbatic acid.

Type: — NEW ZEALAND. North Island: West Auckland, Mt. Albert , October 2011, Blanchon 4629 (holotype AK!, isotype F!, UNITEC!) .

Phylogenetic notes: —Strongly supported as a monophyletic lineage in concatenated multilocus gene tree ( ML bootstrap = 100%; posterior probability = 1.0). Cladia blanchonii was named clade 2 previously ( Parnmen et al. 2012).

Reference sequence: — GenBank No. KC148367 .

Distribution and habitat: —Widespread in New Zealand and also found in Tasmania and south-eastern continental Australia. Mostly specimens were found on mossy soil and rocky outcrops.

Etymology: —The new species is named after our colleague and friend, the New Zealand lichenologist, Dan Blanchon, who has collected the type material of this species.
