Drei parasitische Flechten aufCaloplaca polycarpoides

No less than 3 different parasitical lichens were found on the corticolous lichenCaloplaca polycarpoides in Afghanistan. Partly, they also grow on closely allied species of the sect.Xanthoriella. Lecania triseptata begins and ends as a typical parasite, and does not form a thallus outside of its host.L. diplococca andRinodina afghanica, both described as new species, have a similar appearance; they are parasitic in the beginning, but form their own thalli outside the host later on. The 3 species are members of the small group of parasitical lichens growing on corticolous hosts. Possibly, the slow degeneration of cortices under the arid climatical conditions, has allowed the evolution of parasitic lichens of this rare type in Central Asia.

Omphalotaceae fam. nov. undPaxillaceae,ein chemotaxonomischer Vergleich zweier Pilzfamilien derBoletales

TheOmphalotaceae fam. nov., which include the generaOmphalotus andLampteromyces, are defined on the basis of characteristic sesquiterpenes and of their ability to cause white-rot. Anatomical and morphological features of the representatives of these genera support the creation of this new family. The occurrence of pigments, typical of theBoletales, and of cyanophilous spores, indicate membership of theOmphalotaceae in the orderBoletales. Relationships to the other families of this order — especially to thePaxillaceae — are discussed. The possible functional significance of fungal metabolites is considered.

Chaenothecopsis consociata — kein parasitischer oder parasymbiontischer Pilz,sondern lichenisiert mitDictyochloropsis symbiontica,spec. nova

Chaenothecopsis consociata regularly is lichenized withDictyochloropsis symbiontica, nova spec., a member of theChlorococcales. During early developmentChaenothecopsis consociata possibly parasitizes onChaenotheca chrysocephala.—Dictyochloropsis symbiontica is characterized by its hollow spherical chloroplast which consists of a complex threedimensional network, the absence of a pyrenoid, and the possession of one central nucleus. It reproduces by autospores as well as by zoo- and aplanospores.

Pollen morphology ofSonchus and related genera,and a general discussion

The pollen morphology of the taxa belonging to the generaAetheorhiza Cass.,Launaea Cass.,Reichardia Roth andSonchus L. in the Iberian Peninsula has been studied with light and electron microscopy. The pollen is 3(-4)-zonocolporate and echinolophate (without polar lacunae, but in general with prelacunae), with equatorial ridges and 15–20 lacunae: 3–4 poral, 6–8 abporal and 6–8 paraporal. Small to medium size, P × E = 19–36 × 23–42 µm; sometimes two different sizes have been found. Exine 3–9 µm thick and ornamentation microreticulate and echinate. The results clearly show the relationships between genera. Moreno-Socías, E., Mejías, J. A., Díez, M.
