The holotype (Fig. 8) consists of six small fragments in good condition, along with a small and fragile fragment. Isidia are or were present on all specimens; the latter can be identified by the marks that are left where the isidia broke off. A fragment is covering a

|

<paragraph pageId="7" pageNumber="8">There are frequent laminal ciliary bulbs in the holotype. Part of the observed laminal bulbs were first interpreted as poorly developed pycnidia or even parasitic fungi, which has been proven wrong. Besides being generally small in size also in the margins, some of the laminal bulbs are poorly developed.</paragraph>
|
||
<paragraph pageId="7" pageNumber="8">This is one of the species with the narrowest laciniae in the genus, barely exceeding 0.5 mm in width. The cilia are evidently bulbate, with very small bulbs. Bulbs were not seen in the rhizinae, and if they occur, they should be rare and very subtle. The isidia are very small and appear as unornamented, darkened grains. When detached, they can leave strong marks, resembling spilled medulla that comes out through the cortex. They are easily distinguishable from maculae.</paragraph>
