Laboulbeniales are a highly specialized group of fungi living only on arthropods. They have high host specificity and spend their entire life-cycle on an arthropod host. Taxonomic characters of Laboulbeniales are based on the architecture of the cells of the parenchymal thallus, i.e. the visible part of the fungus outside the host. The extent of the fungus spreading inside the host\—the haustorium\—remains largely unknown. The attachment to the arthropod host is fundamental to understand the fungus-animal interaction, but how this truly occurs is unclear. Recent evidences question the strictly parasitic life-style of Laboulbeniales. We used micro-computed tomography (\µCT) and 3D reconstructions to visualize, for the first time, the complete structure of Laboulbeniales species in situ on their hosts. We compared the haustoriate species, Arthrorhynchus nycteribiae on an insect host to the non-haustoriate species, Rickia gigas on a millipede host. Our results confirm that some Laboulbeniales species are ectoparasitic and have a haustorial structure that penetrates the host\’s cuticle, while others are ectobionts and are only firmly attached to the host\’s cuticle without penetrating it. The presence and the morphology of the haustorium are important traits for Laboulbeniales evolution, and key factors for future understanding of host dependence and specificity.

The first eyeless species of the suborder Spirostreptidea, Odontostreptus fadriquei sp. nov., is described from a cave in Morocco. The new species, which exhibits some troglomorphic traits, is compared with the highly variable O. maroccanus (Attems, 1914) of which new material is presented.

Nine new species of the genus Rickia parasitizing Diplopoda are described: R. appendicifera from Iran on Chiraziulus, R. candelabriformis from Australia and New Zealand on several Spirostreptida, R. galatheae from New Zealand on Eumastigonus, R. gigas from Tanzania on \‘Spirostreptus\’ and Archispirostreptus, R. lophophora from Tanzania on some genera of Spirostreptidae, R. obelostrepti from Tanzania on Obelostreptus, R. odontopygiidarum from Tanzania on Odontopygidae, R. platessa from Singapore and Thailand on Pachybolidae, and R. rhynchophora from Australia on Trigoniulus.\  This nearly triples the previously known number of species of Rickia species on millipedes; all 14 species are treated in this study with photomicrographs, additional observations on previously described taxa and comments. A key to these species is also provided. The Laboulbeniales species were found on millipede specimens preserved mostly at the Natural History Museum of Denmark, from samples collected between 1916 to the present.
