The Strigulaceae are constituted in a different manner from Harris (1975). Eriksson (1981) pointed out
the family should be restricted excluding the Monoblastiaceae, Pleurotremataceae and Xanthopyreniaceae, a
proposal supported by more recent studies. The Phyllobatheliaceae are placed in synonymy here as they
have the same ascus type, apically free physes, ellipsoidal microconidia, septate macroconidia with gelatinous
appendages and trentepohlioid photobiont.
1. Ascomata solitary, not surrounded by pseudostromatic wart filled with dark
granular material; pycnidia solitary; macroconidia usually with eccentric attachment
and bipolar gelatinous appendages (except species with muriform ascospores?);
on leaves, bark, wood or rock ........................................................................................................Strigula

granular material; pycnidia aggregated; macroconidia with basal attachment
and an apical gelatinous cap; on leaves ..........................................................................[Phyllobathelium]
PHYLLOBATHELIUM (Müll. Arg.) Müll. Arg.
Phyllobathelium is not known from North America. Following Santesson (1952) and Lücking (1992) I
would recognize three foliicolous and one corticolous species. Mayrhofer (1987) added a corticolous and a
saxicolous species. On this account I initially considered uniting Strigula and Phyllobathelium. However,
examination of the species recognized by Santesson and Lücking revealed a number of characters that
support recognition of both genera, pseudostromatic ascomatal warts, aggregated pycnidia and basally
attached macroconidia (illustrated by V_zda, 1984) with an apical cap (not tapering appendages as in
Strigula). The two non-foliicolous species recognized by Mayrhofer are transferred to Strigula below. Although
Mayrhofer understood their general relationship, I suspect Strigula did not occur to him since in 1987 the
present day plethora of muriform-spored species were as yet unrecognized.

Specific limits in Strigula pose a number of problems. The corticolous and saxicolous taxa have the usual
problem of overlapping ascospore and macroconidia sizes and possible significance of spore arrangement in
the asci. The foliicolous taxa seem to me (a nonspecialist) based more on the aspect or pattern of growth of
