Skyttea gregaria Sherwood, D. Hawksw. & Coppins
Trans. Br. mycol. Soc. 75: 486 (1981 ['1980']).—Rhymbocarpus gregarius (Sherwood, D. Hawksw.
& Coppins) Triebel, Bibl. Lichenol 35: 144 (1989); type: Great Britain, NW Yorkshire (V.C. 65),
Swaledale, Downholm Park, on Mycoblastus fucatus, 20 viii 1969, Coppins (E—holotypus, non
vid.).
For a description and illustrations, see Sherwood et al. (1981).
Host. This species seems to be restricted to Mycoblastus fucatus (syn. M.
sterilis). The literature records on Lecanora farinaria (Tonsberg 1992) and on
an unidentified lichen crust (Santesson 1993) almost surely refer to other
species, such as S 1 . lecanorae.
Distribution. Austria, Finland, Germany, Great Britain, Norway, Slovenia,
Spain, Sweden and USA (Muhr 1987; Santesson 1993; Hafellner 1994a;
Wirth 1994; Berger 1996).
Observations. Skyttea gregaria is very similar to S. elachistophora and S 1 .
thelotrematis, and also to specimens of S. mayrhoferi in which the brown, K+
violet pigment is indistinct (for differences, see the identification key).
Specimens on unusual or unidentified hosts resembling S. gregaria can be
identified by careful study of the ascomatal characters with a good quality
dissecting microscope.
