摘要:
The squamulose pyrenocarpous lichen Neocatapyrenium disparatum from Texas is described as new. It is the only species of the genus so far known to occur outside Eurasia. Morphologically it resembles N. cladonioideum from eastern Asia but differs in having a finely scabrid thallus surface and smaller ascospores. A key to the five known species is provided.
