Cladia cryptica Parnmen & Lumbsch , sp. nov. ( Fig. 3B ). Mycobank No.: 803449

Characterized by inflated sterile pseudopodetia, with glossy, yellow to brownish surface, mostly dichotomously branched toward the apex. Perforations abundant. Conidiomata on terminal branches of sterile pseudopodetia, conidia 5–7.5 µm long, bacilliform. The sizes of fertile pseudopodetia are variable, with yellow to brownish yellow surfaces, racemosely branched. Apothecia on terminal branches of fertile pseudopodetia, 0.5–1.0 mm wide, disk concave to plane, brownish black; ascospores ellipsoid, non-septate, hyaline, 7–10 × 2.5 µm, 8 per ascus. Secondary chemistry: two chemical races were found: I) Barbatic acid and 4- O -demethylbarbatic acid, and II) stictic acid chemosyndrome.

Type: — NEW ZEALAND. South Island: Southland, Mistletoe Lake , Te Anau Downs, 45°12’S 167°49’E, 218 m, Knight 61705 (holotype AK!; isotype F!) .

Phylogenetic notes: —Strongly to moderately supported monophyletic lineage in concatenated multilocus gene tree ( ML bootstrap = 83%, posterior probability = 1.0). Cladia cryptica is identical to clade 3 in Parnmen et al. (2012).

Reference sequence: — GenBank No. KC148368 .

Distribution and habitat: —Known from Australia, New Zealand and Malaysia. It is found on soil, grassy soil and rocks. In Tasmania, we found this species in dry sclerophyll forests.

Etymology: —The epithet cryptica refers to the fact that the species has been hidden under the name of the species complex C. aggregata .
