Allographa norvestitoides (Sutjaritt.) Lücking & Kalb , comb. nov.

Mycobank MB 827657

Basionym: Graphis norvestitoides Sutjaritturakan , in: Lücking et al., Lichenologist 44 (3): 391 (2012).

Type:— THAILAND. Nakhon Ratchasima province, Khao Yai National Park , forest behind former heliport, on bark of an unidentified tree in a secondary forest, 700 m, J. Sutjaritturakan 12763 ( RAMK!, holotype) .

Thallus corticolous, whitish grey to pale green-gray, continuous, smooth to uneven, corticate, slightly glossy. Lirellae prominent, with distinct lateral and thin to very thin complete thalline margin, short to elongate, up to 10 mm long, straight or curved, simple or sparsely branched, labia convergent, entire, becoming finely striate, covered by a thin thalline cortex, disc concealed, (acharii- morph). Exciple completely carbonized; hymenium strongly inspersed (type B); ascospores 4–8/ascus, hyaline, terminally muriform, with 15–21 transverse septa and 1–2 longitudinal septa in the terminal segments, 60–100 × 10–15 μm.

Chemistry: norstictic acid (major), ± connorstictic acid (minor).

Distribution and habitat:— Allographa norvestitoides is so far only known from Northeast Thailand (type locality). It is growing on bark of an unidentified tree in a secondary forest at 700 m.

Remarks:—The name (as Graphis norvestitoides ) was first mentioned in Lücking et al. (2009), but no description was provided. Therefore, the name was subsequently validated in Lücking et al. (2012). Unfortunately, the species is misplaced in the world key (group 18, hymenium clear), but it should key out in group 20 (hymenium inspersed). This lapsus was already corrected in Bárcenas Peña et al. (2014).The species is similar to Allographa vestitoides (Fink) Lücking & Kalb (see below), but the latter differs in having a clear hymenium and in lacking secondary lichen products. Great care must be taken when investigating the ascospores, because the longitudinal septa in the terminal segments are not always easy to recognize and not present in all ascospores.
