Efforts for legal protection of lichens in Hungary from 1999 to 2004 were summarised
in a former presentation during the XVIth Symposium of Mycologists and Lichenologists of
the Baltic States, Latvia, September 2005. Due to our activities 5 lichen species (Cetraria
aculeata, Cladonia magyarica, Usnea florida, Xanthoparmelia pseudohungarica and X.
subdiffluens) became protected by law (23/2005(VIII.31) KvVM) in August 2005. Further 3
lichen species of the genus Cladina (C. arbuscula, C. mitis and C. rangiferina) were included
in an additional law (18/2008(VI.19) KvVM) for conserving further rare and endangered
organisms in Hungary. However, recent studies emphasize that Hungarian populations of
these species need taxonomic revision urgently. Our forecast about a better understanding of
the importance of biodiversity seems to be fulfilled. We still hope that even more species will
gain protection in future and our results in taxonomy will support conservation of lichenised
fungi.

The Gyalectaceae and Coenogoniaceae are families of lichenized ascomycetes. The
family Gyalectaceae includes widely distributed species. Coenogoniaceae occur mainly in
tropical regions. Morphology and anatomy of these families is poorly investigated.
The aim of our research is to study the spore ornamentation and apothecia surface in
the lichen families Gyalectaceae and Coenogoniaceae by the method of scanning electron
microscopy. Totally twenty four species were investigated. The spores and apothecia were
examined and photographed in JSM 63 90 LA scanning electron microscope (SEM).
The lichens from families Gyalectaceae and Coenogoniaceae can be divided into five
groups on the basis of spore ornamentation: 1) smooth, without ornamentation – Belonia
herculina, B. russula, Coenogonium luteum, C. pineti, Gyalecta derivata, G. friesii, G.
jenensis, G. kukriensis, G. leucaspis, G. liguriensis, G. schisticola, G. subclausa, G. titovii, G.
truncigena, G. ulmi, Pachyphiale carneola, P. fagicola, P. ophiospora, Ramonia luteola; 2)
with poorly developed ornamentation – Gyalecta flotovii; 3) slightly verrucose – Gyalecta
foveolaris, G. peziza; 4) verrucose – Gyalecta geoica; 5) areolate – Gyalecta nigricans.
Some information concerning apothecia surface has been obtained. Margin surface is
similar for all studied species. According to the disc surface, species were divided into three
main groups:
