Descripsit Rob. Fries. 
In caldario horti publici Gothoburj ensis — ubi non raro pro- 
veniunt notabiles Hymenomycetum forma3 — ad Bambusce truncum 
e Batavia reportatum fungum facie prorsus aliena recedentem 
observavit borti Director G. Lowegren et laete vigentem mecum 
benevole communicavit. Cujus h. 1. liceat descriptionem et icones 
inserere. 
Laschia testudinella. 
Pileus membranaceus, gelatinoso-elasticus, ex orbiculari reni- 
formis, leviter convexus, glaber, e griseo fuscescens, obscurius 
areolato-reticulatus ; stipes lateralis, horizontalis, perbrevis ; pori 
ampli, profundi, regulares, hexagoni, similares et concolores ; 
sporae copiosas, oblongae, albae. 
Habitus exacte Hexagonce diminutas, substantia vero gelatinosa, 
licet subrigidula. Sicca valde contrahitur, formam tamen servans ; 
humectata denuo in pristinum modum intumescit. Pileus ^-1 
unc. latus, juniorum orbicularis subgriseus, adultorum reniformis 
fuscescens, peculiari modo tessellatus, dissepimentis pororum 
membranam tenuem pellucidam subruguloso-translucentibus 1. 
potius obfuscantibus. Inde similitudo, quasdam cum scuto dorsali 
testudinum apparet. 
Pl. 172 B., Fig. I., exemplar junius ; Fig. II., adultum refert, 
utrum que jam pridem pluries alternatim siccatum et aqua redi- 
vivum ; ideo nonnihil diminuta, pavimento pilei minus manifesto ; 
Fig. III., specimen juvenile siccum duplo auctum delineat.
