Both are in good condition, only slightly damaged, and not glued to cards, which made the investigation of the lower cortex possible. Inside the packet are small envelopes, containing very small fragments and loose/detached apothecia.</paragraph>

(1984) also described the upper cortex as "not maculate on young lobes, becoming more or less maculate elsewhere". I found that distal parts of the younger lobes show no signs of maculae, but in most of the thallus, especially the older parts, the maculae are punctiform and dense, like those observed in species such as

<paragraph pageId="5" pageNumber="6">Most of the cilia present typical inflated bases, but it is not uncommon that cilia without inflated bases are occasionally found among groups of cilia with inflated bases. Interestingly, in some cilia the bulb is displaced from the base. However, it is hardly found above the first third of the cilia length. It is uncertain why some cilia have no bulbs; maybe they were aborted or maybe they are not formed until a later stage of development.</paragraph>

The lower cortex is almost entirely brown, and in a few small spots more restricted to the central portions of the thallus it becomes a little darker.

the cortex could become almost whitish in some parts, but due to colour change after longer stay in the herbarium it is difficult to confirm this assertion. Most of the rhizinae have basal or displaced bulbs.

(1984) commented on the presence of black dots he supposed to be pycnidia, but he did not found sterigmata or conidia. In fact, conidia are difficult to find in the type material, but when they are found the size and shape is typical for the genus. At the first sight the pycnidia were taken for laminal ciliary bulbs or parasitic fungi, but this was proven to be incorrect.
