New Additions to the Lichen Flora of Texas and the United States
Abstract
Five lichen taxa are new to Texas including Parmotrema mordenii (Hale) Hale, which is new to the United States. Known North American distributions for several taxa are extended. The known lichen flora of Texas has been compiled by Robert S. Egan (1978) through literature and field work over the past few years; however, on account of the size of the state, many areas have not been adequately collected. As a result, the distribution of many lichens within Texas is not well known. Our recent work, conducted for the past two years in the north-central Texas region, has revealed five taxa new to the state of Texas, of which Parmotrema mordenii (Hale) Hale is new to the United States. The ecological setting at all of the collection sites is basically the same--oak woodland with intermittent grassland and occasional rock outcroppings. Corticolous lichens predominate in the north central Texas region, followed by saxicolous, then terricolous substratepreferring species. All lichens in the following list are new to Texas and the species new to both Texas and the United States is indicated by an asterisk. All specimens are in the private herbarium of the senior author. Cladonia robbinsii Evans. PALO PINTO CO.: 3.4 km S, 2.4 km E of Santo, sandy soil and soil or moss in rock crevices, elev. 275 m, Jackson 109.

Its collection in Texas is, perhaps, not unexpected, but extends the known North American distribution southwestward to north central Texas. Lecanora novomexicana Magn. TARRANT CO.: 0.8 km W, 0.8 km N of the intersection of State Hwy. 360 and the West Fork of the Trinity River, Fort Worth, rock outcrops in well-exposed areas, elev. 160 m, Jackson 14. This species occurs in the western states of North America and extends eastward only as far as the eastern New Mexico border and probably southward into the western tip of Texas. However, this species is new to the state and its collection in north central Texas provides a significant eastward extension to its known distribution. *Parmotrema mordenii (Hale) Hale. PALO PINTO CO.: 3.4 km S, 2.4 km E of Santo, rock in wellexposed areas of open woods, elev. 275 m, Jackson 108. According to Hale (1971), the world distribution of this species includes southern Mexico (Chiapas, Veracruz), the West Indies (Dominica, St. Thomas, Grenada, Puerto Rico). The known distribution of this lichen is significantly extended to the north with its collection in north central Texas. Dr. Robert S. Egan has collected this lichen in the Austin, Texas, area (Hale, pers. comm.) although he has not reported it in the literature. Physcia chloantha Ach. TARRANT CO.: 0.8 km W, 0.8 km N of the intersection of State Hwy. 360 and the West Fork of the Trinity River, Fort Worth, rock in open woods (usually this lichen is found on trees), elev. 160 m, Jackson 131. This collection represents the only documented occurrence of the species in Texas. It appears to be rare even in the collection locality. Psora rubiformis (Wahl.) Hook. TARRANT CO.: 0.8 km W, 0.8 km N of the intersection of State Hwy. 360 and the West Fork of the Trinity River, Fort Worth, rock and on soil in rock crevices in sheltered to moderately exposed areas of open woods, elev. 160 m, Jackson 13. We wish to express our thanks to Dr. Robert S. Egan for identification of several of the species and to Dr. Mason E.
