Nephromopsis morrisonicola M. J. Lai
Nomenclatural data
Quart. J. Taiwan Mus. 33: 223, 1981. – Type: [China], Taiwan, Nanton Co., Mt. Morrison, alt. 3500–3900 m, 1978, M. J. Lai 10 438 (TAIM! – holotype)
Morphology
Description see Randlane et al. (1995).
Typical characters. Thallus dorsiventral, upper surface yellow, lower surface black (only the margins may be brown to pale brown). Lobes rather wide (8–15 mm). Medulla white. Pseudocyphellae on the lower surface only.
Chemistry
Contains usnic acid (±) in the cortex; lichesterinic, protolichesterinic and caperatic (±) acids in the medulla.
Remarks
The most conspicuous characters for separating N. morrisonicola from other Nephromopsis species is black underside and white medulla. N. ornata, another taxon with black lower surface, has pale yellow medulla. Some Cetreliopsis species which may also appear similar to N. morrisonicola (e.g. C. asahinae) are readily separated by the presence of pseudocyphellae also on the upper surface and the positive Pd reaction of the medulla.
Ecology and distribution
Distributed in China, Indonesia, Nepal, Papua New Guinea and the Philippines (see Fig. 4 in Randlane & Saag 1998). In China it has been found in Taiwan, Yunnan, now also in Xizang provinces. Corticolous on coniferous (Abies) and deciduous (Betula) trees or shrubs (Vaccinium) in mountainous forests at rather high altitude (2400–4000 m).
