Die 8 bisher in der Gattung Dichodontium eingeschlossenen Arten werden auf 3 reduziert. Dichodontium verrucosum Card. ist synonym mit D. pellucidum (Hedw.) Schimp. Dichodontium opacifolium Dix. ist synonym mit D. brasiliense Broth., wobei die Zugehörigkeit dieser Art zur Gattung Dichodontium nicht vollkommen geklärt ist. Dichodontium nelsonii Kindb. stellte sich als Bartramia pomiformis Hedw. heraus. Dichodontium debile Broth. und D. integrum Sak. bleiben aufgrund von fehlendem Typusmaterial unrevidiert. Dichodontium pellucidum (Hedw.) Schimp. wird lektotypifiziert.
The caatinga is a deciduous and xerophilous vegetation that covers large areas in Brazil. An irregular rainfall with a marked dry period is a characteristic feature. This paper represents the first contribution to the knowledge of the bryoflora from caatinga vegetation in the State of Bahia. The survey was carried out in several areas from Bahia in which eigthteen species of bryophytes were found (15 mosses and 3 liverworts). The bryoflora from caatinga is composed mainly of generalists and xerophilous taxa, but even some hygrophilous species can be found. A number of species including Hyophiladelphus agrarius, Hyophila involuta, Calymperes palisotii ssp. richardii, Bryum argenteum, Entodontopsis leucostega, Octoblepharum albidum, Frullania ericoides also occur in other vegetation types. However, there are a number of species restricted to this type of vegetation, such as Helicophyllum torquatum and Riccia vitalii, at least in Bahia. Most moss species were acrocarpous with erect and short (short-turf) growth-form, whereas the foliose hepaticae were of incubous, and thallose forms.
Several lichen species are reported from the first time from New Guinea, based on material collected by the author in 1995. The following new taxa are described: Crustospathula cartilaginea gen. et spec. nov., Pseudopyrenula serusiauxii spec. nov. and Trypethelium galligenum spec. nov. Psoroma papuana Aptroot & Diederich nom. nov. is proposed as new name for Psoroma pannarioides Aptroot & Diederich.
