Phaeosporobolus alpinus R. Sant., Alstrup & D. Hawksw.
Ascomycota, incertae sedis: forms black, stromatic areas (with hyaline hyphae within) in host thallus and apothecia; conidia of several, smooth, brown subglobose cells surrounding a mother cell. On a number of crustose lichen hosts, including Ochrolechia, Pertusaria and Lecanora, widespread but with few records, undoubtedly much under-recorded.
Refs: to be added, useful generic description by Diederich in Nash et al. (2004), 681.
P. usneae, with more numerous subglobose cells forming the conidia, is a similar species in the thalli of fruticose and some foliose lichens, including Ramalina and Usnea.
